TheA4 motorway (Croatian:Autocesta A4) is amotorway inCroatia spanning 97.0 kilometres (60.3 mi).^[1] It connects the nation's capital,Zagreb, to the city ofVaraždin and toBudapest,Hungary via theGoričanborder crossing.^[2] The motorway represents a major north–south transportation corridor in Croatia and is a part ofEuropean routesE65 andE71.^[3] The A4 motorway route also followsPan-European corridor Vb.^[4]

Apart from Zagreb and Varaždin, the A4 motorway runs near a number ofCroatian cities, and connects to the rest of the Croatian motorway network east of Zagreb. The motorway route was completed in 2008. The motorway's national significance is reflected in the positiveeconomic impact on the cities and towns it connects, as well as its importance totourism in Croatia.^[5] The genuine importance of the motorway as a transit route will be demonstrated upon completion of proposed expansion ofPort of Rijeka and Rijeka transport node, since the A4 represents an integral part of theRijeka–Zagreb–Budapest transport route.^[6][7][8]

As the route traverses hilly terrain, it requires a substantial number ofviaducts andtunnels, as well as two majorbridges to span theDrava andMura rivers. The motorway consists of twotraffic lanes and anemergency lane in each driving direction separated by acentral reservation. There are no emergency lanes in the tunnels. All intersections of the A4 motorway aregrade separated. As of October 2010, there are 12 exits and 3 rest areas operating along the route.^[9] As the motorway istolled using aticket system, each exit includes a toll plaza. Exits south of the Sveta Helena mainline toll plaza have no toll plazas, as that part of the A4 route is not tolled. The same applies to the northernmost section between the Goričan exit and the Hungarianborder.^[10]

A motorway connecting Zagreb to Varaždin and Budapest was proposed in the early 1970s, but unlike the Zagreb–Rijeka or Zagreb–Belgrade motorways, no construction was actually carried out.^[11] The first section of the road, later designated as the A4 motorway, was developed as a 6-kilometre (3.7 mi) two-lane road to serve as an interchange ramp inIvanja Reka. The majority of the entire motorway was built between 1997 and 2003, leaving only a 1.6-kilometre (0.99 mi) section between the Goričan interchange and the Goričan–Letenye border crossing left to build. The section was fully completed on October 22, 2008. In 1998, construction costs were estimated at 850 millionGerman marks (€434.5 million).^[12] Although a 32-yearconcession for development of the motorway was awarded to Transeuropska Autocesta d.d. (TEA) in 1997,Hrvatske autoceste took over development, maintenance and management of the route in 2000 when the concession was cancelled, leading to a dispute withAstaldi, the majority owner of TEA.^[13][14]

The A4 motorway is a significant north–south motorway in the northernCroatia connecting the nation's capital,Zagreb, to theHungarianM7 motorway at theGoričan border crossing^[15] The southern terminus of the A4 motorway at theinterchange in Ivanja Reka represents its junction with the rest of theCroatian motorway network via theA3 motorway.^[16] As a part of theroad network of Croatia, the motorway is a part ofEuropean route E65 andEuropean route E71.^[3] The motorway is of major importance to Croatia in terms of the development of itseconomy, notablytourism, as it represents the shortest and the most comfortable route betweenBudapest, Hungary and theAdriatic Sea. This particularly applies to tourist resorts on theIstria andKvarner Gulf islands and to thePort of Rijeka, but it is also true for resorts in theDalmatia region, served via theA1 motorway. The genuine importance of the motorway as a transit route will be demonstrated upon completion of the proposed expansion of the Port of Rijeka and Rijeka transport node. This expansion is planned to encompass the growth of the Port of Rijeka's cargo handling capacity,^[6][7] improved railroad links and a new Rijeka bypass motorway linking theA6, via a new interchange, to the present routes of theA7 andA8 motorways. The project is, among other goals, aimed to increase traffic along the Croatian part ofPan-European corridor Vb, of which the A4 motorway is a part.^[4][8][17]

The motorway spans 97.0 kilometres (60.3 mi) between the Goričan border crossing to Hungary and Zagreb–Ivanja Reka interchange on the A3 motorway. Among other cities and towns, it connects toČakovec via theD20,Ludbreg andKoprivnica via theD530 andD2,Varaždin via theD528,Novi Marof via theD22,Vrbovec andKriževci via theD10 state roads andDugo Selo via the Ž3034 county road. Future development of the motorway will include additional rest areas and a possible expansion of interchanges.^[2] The A4 motorway consists of twotraffic lanes and anemergency lane in each driving direction along its entire length, except in tunnels where there are emergency bays instead. All existing interchanges aretrumpet interchanges, except in Ivanja Reka, which is a modifiedcloverleaf. There is a number ofrest areas along the motorway, providing various types of services ranging from parking spaces and restrooms tofilling stations and restaurants.^[9][18] As of October 2010, the motorway has 12 interchanges, providing access to numerous towns and cities and theCroatian state road network. The A4 motorway isconcurrent with theD3 state road between the Komin and Ivanja Reka interchanges, although the D3 is not signposted along that section.^[1] The motorway is operated byHrvatske autoceste.^[13][19]

An automatic traffic monitoring and guidance system is in place along the motorway. It consists of measuring, control and signaling devices, located in zones where driving conditions may vary—at interchanges, near viaducts, bridges, tunnels and in zones where fog and strong winds are known to occur. The system consists ofvariable traffic signs used to communicate changing driving conditions, possible restrictions and other information to motorway users.^[20]

The A4 motorway runs through hills and plains crossed by a number of watercourses, requiring a number of bridges, viaducts and tunnels along the route. Particular attention to the environment is also required, due to the several water supply andnatural heritage zones.^[9]

The A4 is atolled motorway based on thevehicle classification in Croatia using aclosed toll system. As of October 2010, toll charged along the A4 route between theSveta Helena and Goričan mainline toll plazas varies depending on the length of route travelled and ranges from 7.00kuna (€0.96) to 36.00 kuna (€4.93) for passenger cars and 22.00 kuna (€3.01) to 120.00 kuna (€16.44) forsemi-trailer trucks.^[21] The toll is payable in either Croatian kuna or euros using major credit cards, debit cards and a number of prepaid toll collection systems. The latter includes various types of smart cards issued by the motorway operator andENC, anelectronic toll collection (ETC) system which is shared at most motorways in Croatia and provides drivers with discounted toll rates for dedicated lanes at toll plazas.^[22] The northernmost section of the motorway, between the border and Goričan interchange (inclusive) is not tolled. Similarly, the southernmost part of the A4 motorway route, located between Sveta Helena and Ivanja Reka interchanges (inclusive) is also toll-free, as it is a part of theZagreb bypass, which services a significant volume of traffic.^[10][21][23]

The A4 motorway Varaždin–Breznički Hum section route runs through hilly landscape requiring a number of viaducts and tunnels, especially along the Breznički Hum–Novi Marof section and around theVaraždinske Toplice exit. Each comprises four traffic lanes, while the viaducts have emergency lanes. Two most notable structures are theHrastovec andVrtlinovec tunnels, located to the south and north of the exit, respectively. Both of the tunnels consist of two tubes each, and each of them carry two traffic lanes. The Hrastovec Tunnel tubes are unequal in length, as the southbound tube is 498 metres (1,634 ft) long, while the northbound tube is 523 metres (1,716 ft) long.^[24] The Vrtlinovec Tunnel southbound tube is 628 metres (2,060 ft) long and its northbound tube is 522 metres (1,713 ft) long, earning the distinction of being the longest tunnel on the A4 route.^[25] There are two major bridges on the A4 motorway, both of them located north of Varaždin. The longest one is theDrava Bridge, carrying the motorway across theDrava River, measuring 507.7 metres (1,666 ft) long. There is also theZrinski Bridge, carrying the A4 motorway acrossMur River and across the Croatia–Hungary border, thus representing the northern terminus of the motorway, where northbound A4 traffic defaults to the Hungarian M7 motorway towardsNagykanizsa and Budapest. The 216-metre (709 ft) Zrinski Bridge was the final structure completed on the route. Both the Drava and Mura bridges carry six motorway lanes.^[26]

A motorway connecting Zagreb to Varaždin and Budapest was proposed in the early 1970s, but unlike the Zagreb–Rijeka and Zagreb–Belgrade motorways, no construction was carried out.^[11] Although the first section of the route, now designated as the A4 motorway, was completed in 1980, development for the motorway was proposed once again in 1991 to facilitate links between the Varaždin area, Zagreb and the remainder of the Croatian motorway network.^[27] The route was added to the network of Pan-European transport corridors in June 1997, during the thirdPan-European Transport Conference inHelsinki,^[28] and on August 7, 1997, the government of the Republic of Croatia decided to establish the Autocesta Rijeka–Zagreb–Goričan company and award it a 28-yearconcession to develop, operate and maintain the route as a six-lane motorway. The route consisted of the entire Croatian section of the Pan-European corridor Vb except for 20.8-kilometre (12.9 mi) of theLučko–Ivanja Reka section of the A3 motorway, which was already in use as a part of Zagreb bypass.^[29]

Later that same year, on May 14, 1998, the government signed an agreement withAstaldi, regulating construction of the Zagreb Goričan motorway by 2000.^[30] On December 11, 1997, pursuant to the agreement, the government established theAutocesta Rijeka–Zagreb company to take the place of the Autocesta Rijeka–Zagreb–Goričan company, and awarded it the 28-year concession to develop, maintain and operate the Zagreb–Rijeka motorway, effectively excluding the Zagreb–Goričan motorway from the original concession.^[31] At the same time, the Transeuropska autocesta d.o.o. (TEA) company was established by the government and awarded concession for development, operation and maintenance of the Zagreb–Goričan motorway.^[32] Astaldi owned 51% of TEA, with the remainder owned by the Republic of Croatia. TEA was to secure financing of the project in 1998.^[30][33] Construction began as scheduled; however, financial and legal problems ensued, and by 1999, the press speculated that Astaldi had given up the project, but Astaldi repeatedly denied these claims.^[34][35] Ultimately, the government cancelled the contract and ceded the motorway to Croatian Roads Administration (ancestor ofHrvatske autoceste andHrvatske ceste), leading Astaldi to turn to the commercial arbitration court in Vienna, which ruled in its favour. The Republic of Croatia was subsequently required to pay Astaldi 44.3 million euro in damages.^[36]

In 1980, the 6-kilometre (3.7 mi)Popovec–Ivanja Reka section was the first part of the A4 motorway to be built, as asemi-motorway, for the new Ivanja Reka interchange on the motorway, later designated A3.^[37] The first section completed was the 16-kilometre (9.9 mi) Goričan–Čakovec section, opened to traffic in 1997, followed by the 22.4-kilometre (13.9 mi)Komin–Popovec and the 15.58-kilometre (9.68 mi) Čakovec–Varaždin sections, completed in 1998.^[38][39] In 2000, the 12.3-kilometre (7.6 mi) Breznički Hum–Komin section was finished,^[27][40] and in 2003, the motorway route was nearly completed as the 23.25-kilometre (14.45 mi) Varaždin–Breznički Hum section and the second carriageway in the Popovec–Ivanja Reka section were built.^[41][42] The final 1.6-kilometre (0.99 mi) section between the Goričan exit and the Hungarian border opened on October 22, 2008, the same day the final section of the A6 motorway was finalised, marking completion of the Budapest–Zagreb–Rijeka motorway.^[43][44]

Traffic is regularly counted and reported by Hrvatske autoceste, operator of the motorway, and results are published by Hrvatske ceste. The largestannual average daily traffic (AADT) volume is often recorded in the Sveta Helena–Komin section, although all sections between Sveta Helena and Varaždin display similar AADT. AADT data for sections north of Varaždin show considerable drops in traffic volume. As the motorway traffic volume is measured through analysis of toll ticket sales, the southernmost section of the motorway, Ivanja Reka–Sveta Helena, is not included in the report. However, since the section is a part of theZagreb bypass, it carries significantly heavier traffic than any other sections of the A4 motorway—in 2004, traffic volume along the toll-free section of the A4 motorway was approximately 24,000 vehicles per day (AADT) between theKraljevečki Novaki and Sveta Helena interchanges and nearly 41,000 vehicles per day between the Kraljevečki Novaki and Ivanja Reka interchanges. Traffic volume measured on the Ivanja Reka–Ivanić Grad section of the A3 motorway increased by 30%, hinting at a similar increase in traffic volume on the A4 route south of Sveta Helena.^[46]

Variations between AADT andaverage summer daily traffic (ASDT) traffic volumes are attributed to the fact that the motorway carries substantial tourist traffic to the Adriatic Sea resorts.^[47]

As of October 2010, there are three rest areas along the A4 motorway. Legislation identifies four types of rest areas designated as types A through D: A-type rest areas comprise a full range of amenities, including a filling station, a restaurant and a hotel or motel; B-type rest areas have no lodging; C-type rest areas are very common and include a filling station and a café, but no restaurants or accommodations; D-type rest areas only offer parking spaces, possibly picnicking tables and benches, and restrooms. Even though rest areas found along the A4 motorway generally follow this ranking system, there are considerable variations, as some of them offer extra services. The filling stations regularly have smallconvenience stores, and some of them may offerLPG fuel.^[48]

The primary motorway operator, Hrvatske autoceste (HAC), leases the A, B and C type rest areas to various operators through public tenders. As of October 2010, there are two such rest area operators on the A4 motorway:INA andCrodux. The rest area operators are not permitted to sub-lease the fuel operations. The A4 motorway rest areas are accessible from both directions of the motorway and operate 24 hours a day, 7 days a week.^[18]
