TheA47 is a major trunk road inEngland linkingBirmingham toLowestoft,Suffolk, maintained and operated byNational Highways. Most of the section between Birmingham andNuneaton is now classified as theB4114. FromPeterborough eastwards, it is atrunk road. (Sections west of theA1 road have been downgraded as alternative roads have been built.)

The original (1923) route of the A47 was Birmingham toGreat Yarmouth, but some changes were made to its route in the early years.At its eastern end, the A47 originally ran throughFilby andCaister-on-Sea, with theAcle Straight bearing the number B1140.
A change took place in 1925. The original route of the A47 betweenGuyhirn andWisbech in theIsle of Ely was viaWisbech St Mary, with the direct route being part of the A141. That was because there was no road bridge over theRiver Nene at Guyhirn and hence no junction between the A47 and the A141. In April 1925 a steel road bridge was opened, and the A47 and the A141 swapped routes between Guyhirn and Wisbech.[citation needed]
The A47 was rerouted along the Acle Straight in 1935, with the old route being renumbered as the A1064 (Acle to Caister-on-Sea) and part of the A149 (Caister to Great Yarmouth). Another change also dates from 1935. The A47 originally ran viaDownham Market, not King's Lynn. In 1935,[citation needed] it was rerouted via King's Lynn, replacing part of the A141 (Wisbech to King's Lynn) and part of the A17 (King's Lynn toSwaffham). The old route via Downham Market was renumbered as the A1122 (Outwell to Swaffham) and part of the A1101 (Wisbech to Outwell).
Major improvements were made from the late 1970s until early in the 1990s. The seven-mile (11.3 km) £5 million part-dual-carriagewayEast Dereham Bypass built on part of the disused railway line was opened in spring 1978 followed by a five-mile (8 km) part-dual-carriageway Swaffham Bypass, costing £5 million, which was opened in June 1981. Bypasses for Uppingham (£1.4 million) and Blofield (£4 million) were opened in 1982 and 1983 respectively. The southern section of the Great Yarmouth Western Bypass was opened in May 1985 and the northern section in March 1986 at a cost of £19 million, followed by improvements to the one-mile (1.6 km)Postwick-Blofield section (£1.2 million), which was opened in November 1987. In 1989 Acle Bypass was completed at a cost of £7.1 million and the £1.2 million East Norton Bypass was opened in December 1990. The three-mile (4.8 km) £9 million East Dereham-North Tuddenham Improvement opened in August 1992 and the £62 million Norwich southern Bypass in September 1992.
Escalatingroad protests starting withTwyford Down in 1992 and culminating with theNewbury bypass in 1996 (at which more than 1,000 people were arrested)[4] led to more than 300 road schemes being cancelled in November 1995[5] and to the cancellation of further schemes, including the Thorney bypass,[6] by the newLabour government in 1997.[7][8]
In 2002 the government announced a new road-building programme,[9] which included the three-mile (4.8 km) dual-carriageway Thorney bypass, which opened on 14 December 2005.
In February 2017Highways England (nowNational Highways) redesignated the stretch of theA12 road between Great Yarmouth and Lowestoft as the A47.[10]

A study on the A47 which concluded in 2001 looked at improving New Road, i.e. the section of the A47 between Acle and Great Yarmouth known as the Acle Straight.[11] The improvement of the Acle Straight has become a point of contention between interested parties due to its passage throughthe Norfolk Broads, an area of important ecological and conservation significance that limits development. The study which recommended widening rather than dualling of the Acle Straight was opposed by theBroadland District Council,Great Yarmouth Borough Council,Norfolk Police Authority and the majority of local respondents who believed that dualling of the road is necessary to improve road safety, decrease journey time and support the economic development of Great Yarmouth. Dualling was however strongly opposed by theEnvironment Agency, theCouncil for National Parks (CNP) and theBroads Authority due to its impact on biodiversity and internationally important wildlife sites. These parties did cautiously support further investigation into the option for widening following further investigation of its environmental impact.[12]
In 2006 a programme of safety improvement for the Acle Straight were announced. This would include road resurfacing, better road markings, improved visibility and the installation of safety cameras at an estimated total cost of £1.6 million. The result would then be monitored while long-term improvements, such as widening, are considered.[13]
A £117 million road scheme to the north ofNorwich, linking theA1067 andNorwich International Airport to the A47, sponsored and managed byNorfolk County Council. It was priority scheme for Norfolk County Council and it attracted strong opposition both locally and from environmental groups.[14] On 2 June 2015 the scheme was given the go ahead, in 2017 parts of the road were opened with the complete road opened in early 2018.
A scheme to connect the A47 atEaston with the A1067 atAttlebridge at the end of the Norwich Northern Distributor Road.[15]
The two stretches of dual carriageway west and east of Norwich respectively are planned to be dualled by 2027.[16] Although aDevelopment Consent Order (DCO) was granted in 2022,[17][18] both schemes were subject to legal challenge which have since been dismissed.[19] This caused the overall scheme to be delayed by 20 months.[20] Work began on theNorth Tuddenham toEaston leg in 19 August 2024 and is due to be finished in 2027.[21]
In addition to the two dualling schemes, National Highways also proposed to improve theThickthorn Junction, where the A47 meets theA11. This will involve the construction of two new free-flow link roads between the A47 and the A11. this project was also the subject of a legal dispute which was since dismissed. In July 2024, the £153 million contract was awarded toSkanska with construction to begin later in the year, which will last for four years.[22]
In 2012 Norfolk County Council launched the strategic route prospectus which detailed improvement schemes along the A47 between Peterborough and King's Lynn.[23] The list of improvements, costing a total £526 million, included dualling sections of the road and other junction improvements. The sections of the road to be dualled were the Acle straight, Blofield toBurlingham, North Tuddenham to Easton and theEast Winch/Middleton bypass. Other improvements detailed were four schemes at Great Yarmouth, including a £112 million third river crossing, four junction improvements along the Norwich Southern Bypass and improvements to the three junctions at King's Lynn.
On 8 October 2012 it was the announced that improvements to the A1/A47 junction at Wansford and the roundabout at Honingham would be approved for pinch point funding.[24] On 1 December 2014 it was announced that a package of improvements to the A47 worth a total of £300 million would be funded during the 2015–20 parliament.[25]
Plans to dual the A47 west of Peterborough betweenWansford andSutton were cancelled by the government in August 2025.[26]

The Birmingham end of the A47 starts one mile from the centre of Birmingham at the junction with theA4540 Middleway. The traffic light controlled junction was laid out in 2018–19 following the infilling of the Ashted Circus roundabout.[27][28] The road runs north-east through Vauxhall as Nechells Parkway and then Saltley Road. (Historically it started in the City Centre on High Street.) The road continues north east following theCross Country Route andRiver Rea as first Heartlands Parkway and then Fort Parkway. The Birmingham section of the road terminates atSpitfire Island, aroundabout on theA452 halfway between the M6 Junction 5 and A38 Tyburn Island.
The route between Birmingham and Nuneaton was known as the A47 until 1986, when it was renumbered, mainly as the B4114, following the completion of the M42.[citation needed]

AtNuneaton the road re-emerges as Hinckley Road from a junction with theA444, near therailway station. Leaving Nuneaton, it passes theNorth Warwickshire and South Leicestershire College, meets the A4254 at a roundabout and theA5Watling Street near the Longshoot Hotel. It follows the A5 for a half-mile enteringLeicestershire and the district ofHinckley and Bosworth, then leaves at a roundabout to bypass Hinckley to the north as Dodwells Road then Normandy Way which was completed in the summer of 1994.[citation needed] This section passes through a large industrial estate and close to aTesco distribution centre, crossing theAshby-de-la-Zouch Canal. It meets a roundabout near theTriumph motorbike factory. It bypassesEarl Shilton on its southern side as a single carriageway road. It then runs throughLeicester Forest on a line parallel with theM69. It entersLeicester Forest East crossing theM1 near theservice station and continues on into the City of Leicester at the B5380 junction. The road continues into the city centre crossing theA563 outer ring-road before becoming part of the inner ring road.


Leaving Leicester the road becomesHumberstone Road, thenUppingham Road. It passes under theMidland Main Line and meets the B6146St Barnabas Road to the south, then passes over the formerLeicester Belgrave Road toPeterborough North section of theGreat Northern Railway which follows the road as far asHoughton on the Hill. At theA6030 crossroads, it becomes part of the Leicester outer ring road inNorth Evington. AtHumberstone, beyond theA563 (outer ring road) andGoodwood Road (projected extension of the outer ring road) crossroads, the road meets the B667Spencefield Lane to the south, forEvington. Between theDowning Drive junction and Thurnby Hill it enters Leicestershire and the district ofHarborough. AtThurnby it meetsStation Road to the north, forScraptoft. LeavingBushby it climbs Winkadale Hill into the countryside.

The road travels throughHoughton on the Hill, with crossroads forLeicester Airport (to the south) andOld Ingarsby (to the north) next to theRose and Crown andJETHoughton Garage, and heads down Palace Hill with a right turn forGaulby, a left turn for Tilton on the Hill, then crosses theRiver Sence. The two-mile £2.5 million three-laneBillesdon Bypass opened in October 1986, passing north of the village, with staggered crossroads. It meets theB6047 north-southMarket Harborough toMelton Mowbray road (forTilton on the Hill) at staggered crossroads at the highest point of the A47, at around 670 feet. It passes throughSkeffington with a right turn forRolleston then heads throughTugby, which is traversed by theMidshires Way andNational Cycle Route 63. It winds its way towards the one-kilometre £1.2 millionEast Norton Bypass, which opened in December 1990, passing south of the village, with a left turn forLoddington and right turn forHallaton. Leaving the village, after rejoining the former route, it passes the formerrailway station. It heads down a hill as three lanes and crosses theEye Brook and from here the next ten miles are inRutland, and three lanes become two.

There is a left turn forBelton-in-Rutland and a right turn forAllexton (in Leicestershire) where the road is crossed by the Leicestershire Round andMacmillan Way. The two-mile £1.9 millionWardley Hill Improvement opened in October 1987, and there is a right turn (only) for Wardley, where the road is crossed by the Rutland Round. The road improvement took a less-crooked route closer to the village, with a less steep incline avoiding the top of Wardley Hill. The one-and-a-half-mile £1.4 millionUppingham Bypass opened in June 1982, taking a shorter route north of the town, which is the home ofUppingham School. It meets theA6003 (forOakham) at a roundabout, and meets the formerGlaston Road route and crossroads forBisbrooke, to the south. It passes throughGlaston, with crossroads forWing (to the north) andSeaton (to the south) near theOld Pheasant. It passes over the tunnel of theOakham to Kettering Line. EnteringMorcott it passes Redwings Lodge, a formerTravelodge, and a new cafe restaurant, the Country Lounge originally aLittle Chef, on the left and there is a left turn for Morcott, where the road is crossed by the Rutland Round. It meets theA6121 (forStamford) and B672 (forCaldecott) where it crosses a tunnel of a former railway. At a right turn forBarrowden there is Morcott Windmill, and the road is again crossed by the Rutland Round. There is a crossroads forSouth Luffenham andBarrowden.

From Shire Oaks (Coppice Leys) throughTixover, the road has been straightened, and to the right is the Welland Valley (Rutland – Northamptonshire boundary). At Tixover there is a crossroads, where the Rutland Round follows the road to the east. The road crosses theRiver Welland, where theJurassic Way crosses the road. TheDuddington Bypass, where the road enters the district ofNorth Northamptonshire, opened in 1975. This section has a busy roundabout where it meets the south-west/north-east corridorA43. On the northern edge of Collyweston Great Wood, it meetsKingscliffe Road forCollyweston, at the west gate ofRAF Wittering. It follows the perimeter fence of the airfield toCollyweston Cross Roads (now no longer crossroads due to the airfield), where there is a right turn forKings Cliffe. The woodland here is the northern edge of the historicRockingham Forest. The road towards Wittering Lodge has been straightened, and crosses theCity of Peterborough boundary (former Northamptonshire, thenCambridgeshire). At Toll Bar Cottage, there is a left turn forWittering, oppositeBedford Purlieus National Nature Reserve. The road meets theA1.
The road formerly went through Wansford, further to the south. The £250,000 dual-carriagewayWansford North Bypass opened in January 1965. There is a right-turn forSutton. It is crossed by theRoman roadErmine Street. The dual-carriageway £9 millionAilsworth-Castor Bypass opened in September 1991. Around Peterborough, the Peterborough LongthorpeGrade separated junction (GSJ) opened in December 1987 where it meets the A1260. There is a GSJ forBretton and aSainsbury's, and it passes thePeterborough City Hospital. The £1.2 million PeterboroughWestwood GSJ opened in January 1987 nearRavensthorpe. This section of road is called theSoke Parkway (named after theSoke of Peterborough). When this was first built, in the mid-1970s, the A47 followed what is now the A15Paston Parkway.
It crosses theEast Coast Main Line and meets theA15 atNew England near to aMorrisons (formerSafeway), and Boulevard and Brotherhood retail parks atWalton to the north andNew England to the south. There is another GSJ nearPaston to the north and it meets the other strand of the A15 at a GSJ nearGunthorpe. It meets the southern terminus of the newA16 alignment before meeting the A1139 at a roundabout and crossing theCar Dyke. The 3-mile (4.8 km) £7.2 millionEye Bypass opened asEye Road in October 1991, diverting traffic from thePaston Parkway, and partly built on the formerPeterborough to Wisbech railway. There is a local access roundabout atEye Green near theEssoEye Green Service Station, aTravelodge and the Peterborough Eye formerLittle Chef on the right, where it becomesThorney Road,The Causeway. The landscape becomes very flat known asThe Fens. A 3-mile (4.8 km) dual-carriageway bypass ofThorney opened on 14 December 2005. The road meets the B1040 and B1167 at roundabouts. NearThorney Toll, the road entersCambridgeshire and the district ofFenland near theNew Toll Service Station. The straight road finishes at Guyhirn, meeting the B1187 and crossing on theTiddy Mun bridge and following theRiver Nene and the Nene Way. The1⁄2-mile (0.80 km) £3.7 millionGuyhirn Diversion opened in October 1990. The road heads north-east, following the east bank of the River Nene. The 5-mile (8.0 km) £6 millionWisbech/West Walton Bypass opened in autumn 1984. The former route leaves as the B198 at a roundabout. It meets alevel crossing, and it entersNorfolk and the district ofKing's Lynn and West Norfolk just before a roundabout with the A1101 forElm andEmneth at the Elme Hall Hotel. It passes theTotalWisbech Services and then meets the old route (B198) at a roundabout and becomes the 6-mile (9.7 km) £23 million dual-carriagewayWalpole Highway/Tilney High End Bypass which opened in summer 1996. There is an exit for Walpole Highway, and another forTerrington St John. It passes near Tilney High End. NearTilney All Saints, it meets the old route at a roundabout, becoming the single carriagewayMain Road, thenPullover Road. It meets the end of theA17 at the "Pullover Roundabout" where theWest Lynn Little Chef is located.

Nearing King's Lynn, the dual carriageway crosses over theRiver Great Ouse andFen Rivers Way footpath. Construction of the King's Lynn southern bypass, built byW. & C. French[29] at a cost of £3,733,000, began on 5 April 1972[30] and was completed in 1975.[31] It meets theA148 road at agrade-separated junction known as the Saddlebow interchange.[32] TheA10 and theA149 terminate at the Hardwick Flyover (opened on 30 October 2003[33]) near the Hardwick Industrial Estate (formerly home ofCampbell's Soup). After this junction it becomes Constitution Hill until the turn off forNorth Runcton; then Lynn Road, where inMiddleton it passes the Grade II listed former lodge to Middleton Hall, 'The Old Lodge',[34] the former Crown public house and St Mary's church.
Next isEast Winch, where it passes All Saints's church, thenWest Bilney where it passes St Cecilia's church. Soon after, the formerLynn and Dereham Railway line is crossed, followed by a right-turn forPentney, and the B1153 forEast Walton. The half-mileNarborough Bypass, opened in November 1992, where the road crosses theRiver Nar and enters the district ofBreckland. There is a straight section to where it meets the A1122 (forRAF Marham) at a roundabout at the start of the five-mile part-dual-carriagewaySwaffham Bypass, which opened in June 1981. There is an exit for Swaffham, and a grade-separated junction with theA1065 (forFakenham).
It passes some wind turbines and there is a roundabout where it joins the former route just before it is crossed by thePeddars Way. There is a left turn forSporle and it passesNecton then heads north-west throughLittle Fransham, passing theCanary and Linnet, with a left turn forCrane's Corner. The seven-mile £5 million part-dual-carriageway East Dereham Bypass opened in spring 1978, which was built on part of the disused railway line. It passes nearWendling and St Peter and St Paul church then meets the B1146 (for Dereham) and A1075 (forShipdham) near aTesco supermarket and B1135. The B1147 leaves forSwanton Morley. The three-mile £9 million East Dereham-North Tuddenham Improvement opened in August 1992, which passes North Tuddenham. It bypassesHockering. It enters the district ofBroadland at the start of the bypass ofHoningham, where it crosses theRiver Tud. Just before the roundabout atEaston, it enters the district ofSouth Norfolk.
The dual-carriageway £62 million Norwich Bypass opened in September 1992. At theLongwater Intersection, the A1074 follows the former route through Norwich near the Longwater Retail Park andSainsbury's. NearBawburgh, it crosses theRiver Yare. There is a GSJ with the B1108, forLittle Melton andColney. AtCringleford, it meets theA11 at the Thickthorn Interchange andThickthorn Services and crosses theBreckland Line. Near Keswick Hall, it meets theA140 at a GSJ at Harford Bridge, south ofNorwich, near a Tesco, then crosses theGreat Eastern Main Line. It is crossed byBoudica's Way, then meets theA146 at a GSJ. It crosses the River Yare again at thePostwick Viaduct and enters the district of Broadland.
It crosses theWherry Line and meets the A1042 at a GSJ. The section from the end of this bypass toBlofield, the one-mile £1.2 millionPostwick-Blofield Dualling, was opened in November 1987. There is a left turn toGreat Plumstead. The one-mile £4 million dual-carriageway Blofield Bypass opened in February 1983, which starts at a roundabout forBrundall. It becomes single carriageway and passesNorth Burlingham near the staggeredWhite House crossroads with the B1140. The three-mile £7.1 million dual-carriageway Acle Bypass opened in March 1989, which ends at a roundabout with the A1048 near aTravelodge, becoming the single carriagewayNew Road. From Acle, the road enters the Acle Straight which is nearly seven miles of straight and level single carriageway to Great Yarmouth, with just one curve at Road House Diner. The road is notorious for congestion, especially during the holiday season, and also for the number of accidents, which due to the drainage ditches on either side of the road are often fatal, and demands for dualling have been heard for many years, although there are no current plans to go ahead with this. It enters the district of Great Yarmouth, then passes close toBreydon Water. The northern section of the two-mile £19 million Great Yarmouth Western Bypass (A47) opened in March 1986, and the southern section opened in May 1995.


From theAcle Straight, the A47 meets the Vauxhall Roundabout inGreat Yarmouth where it intersects with theA149. The A47 follows a route south acrossBreydon Bridge which spans the estuary where the RiversYare andBure meetBreydon Water. It meets at the Gapton Hall Roundabout, which intersects with the A1243. The route continues South, meeting with the Harfrey's Roundabout, which connects the A47 to Great Yarmouth's Herring Bridge. From there the A47 is formed of theGorleston Bypass, a 2.6KM stretch of dual carriageway with a single slip-road connecting it toGorleston via theA143. After this, a small section of the A47 runs south past the regions main A&E, theJames Paget University Hospital. Approx 5.5 KM of dual carriageway then takes the A47 to NorthLowestoft, which connects the A47 to the coastal villages ofHopton andCorton via 3 roundabouts. The A47 entersSuffolk as its route heads south intoLowestoft, along restricted 30MPH roads. As the A47 intersects with theA1144 in the centre of Lowestoft, it branches off into two routes. The main A47 branches past thetowns docks, where it enters a section of 3 lanes controlled bylane tidal flow lights, which predetermine which of the three lanes is open for north or southbound travel over thebascule bridge. The secondary A47 branches through the centre of the town, passingLowestoft Railway Station and meeting the main A47 by the docks just before the bridge. The A47 then terminates at the Bascule Bridge, where theA12 begins.[35][36]
First Eastern Counties run an 'Excel' service, with four branded routes – A, B, C and D, which primarily serve population centres along the A47, with some routes going as far as Peterborough.[37]
