The section of the N17 fromJohannesburg toSprings is a dual carriageway and is a national toll route. It was the first urbantoll road inGauteng. It runs from theM11 Wemmer Pan Road in Johannesburg toTonk Meter Road in Springs. The first part of the N17 used to be the old R77 which ran from the M46 Rand Airport Road to the R23. As part of the Gauteng Freeway Improvement Scheme, two slip roads have been made linking the N17 to theN12. It is now possible to travel from the N17 West to the N12 West and from the N12 East to the N17 East, both at the Elands Interchange (previously only possible via theN3).[2] From Tonk Meter Road the N17 is a single carriageway freeway. The section fromSprings toLeandra, ending at the interchange with the R50, was constructed by the then Transvaal Provincial Administration (TPA) in 1990 as a single carriageway road. (The R29 ran alongside the N17 from Springs to Leandra).
From Leandra, the N17 then followed the alignment of the R29 to Ermelo, and thereafter the R65 to Oshoek. However, the N17 at that time traversed through four towns (Leandra, Kinross, Trichardt and Bethal) causing delays to the traveling public, and safety risks to the local public, especially pedestrians. The R29 was also badly potholed, and without passing lanes or even shoulders, making the section fromLeandra toErmelo dangerous.
SANRAL commenced with toll feasibility investigations in 2001 for the N17 after which consultants were appointed for the rehabilitation, upgrading as well as design of new sections for the N17 fromSprings toErmelo. In order to enable SANRAL to refund loans for the funding of the rehabilitation project, it was inevitable that the N17 fromSprings toOshoek in theMpumalanga Province would also be declared a continuous toll road and toll plazas would be erected.
The existing single lane carriageway between Springs and Leandra has been rehabilitated with improvements to the vertical and horizontal alignment, paved shoulders, grade separated interchanges at the R548 (Devon/Balfour) and R42 (Delmas/Nigel), and climbing/passing lanes. The new section betweenLeandra andTrichardt (21 km) has been completed, and the first toll plaza at the interchange with the R50 is now open. As of October 2011, the N17 rejoins the old alignment just east of Kinross. Other improvements include a new section pastTrichardt (3 km) and inBethal (1,5 km).
The N17 East Toll Road comprises Section 2, 3, 4 and 5 of the proclaimed N17 route. In general terms the route can be described as the existing N17 betweenSprings andOshoek, with approximately 26 km of newly constructed sections. The total length of the route is 290 km. (330 km with section 1 included)
The N17 begins in the southern suburbs ofJohannesburg, north ofRosettenville, at a t-junction with Wemmer Pan Road (Johannesburg'sM11 road), heading eastwards. It starts by heading for ten kilometres (with two westbound-only off-ramps at theM19 andM31 roads), passing under theN12 highway (Johannesburg Ring Road), to form an interchange with theN3 highway just south ofRand Airport. As part of the Gauteng Freeway Improvement Project, there are now two slip roads linking the N17 to the N12; one linking the N17 West to the N12 West and one linking the N12 East to the N17 East (previously only possible via the N3 freeway).[2] At the N3 interchange is the Gosforth Toll Plaza (the first N17 toll plaza).[1]
From the N3 interchange, the N17 goes eastwards through theCity of Ekurhuleni for thirty kilometres, bypassingGermiston,Boksburg,Benoni andBrakpan, meeting theR21 andR23, toSprings, where there are off-ramp junctions with Tonk Meter Road (M63 road) and Wit Road (R51 road). This marks the end of section 1 of the proclaimed N17 route. On this section, just after the R23 junction in the suburb of Dalpark in Brakpan, is a tollgate (Dalpark Toll Plaza).[1]
The N17 national route continues for 50 kilometres eastwards from the R51 Springs junction, meeting theR42 and bypassingDevon, to cross intoMpumalanga province and reach the town ofLeandra. This marks the end of section 2 of the proclaimed N17 route.[1]
FromJohannesburg, the N17 is followed by theR29 road (parallel fromSprings).[1] This road may be used as an alternative in times when the N17 Section 2 is experiencing issues.[3]
In Leandra, the N17 reaches an intersection with theR50 road, which is the end of section 2. At this interchange, there is a tollgate (Leandra Toll Plaza).[1]
The N17 used to form a Z-shape in Leandra, beingconcurrent with the R50 from this junction north-westwards for 3 kilometers up to the junction with the R29, where the N17 would continue eastwards. But Today, the N17 is a continuous eastwards highway from its primary junction with the R50. (Avoiding the Leandra Town Centre and the upcomingKinross Town Centre by bypassing to the south)
So, as the R29 used to end at the junction with the R50, it now also continues eastwards on that old section of the N17 route through Leandra Central and Kinross Central, remaining an alternative route to the current N17.[1]
From the R50 junction, the N17 continues eastwards for twenty kilometres, bypassingKinross, to meet theR580 road at a point north-east ofEvander and north-west ofSecunda. This junction, known as the Leven Station Junction, also marks the eastern end of theR29 route (the N17 highway no longer has a parallel route following it for the remainder of its length) (the N17 continues eastwards on its old alignment from here).[1]
From the R29/R580 junction, the N17 continues eastwards for another ten kilometres to reach the town ofTrichardt. As the N17 used to pass through the Trichardt town centre, it has now been realigned to bypass it to the north, remaining one continuous main road.[1]
From Trichardt, the N17 continues eastwards for 25 kilometres, through the Trichardt Toll Plaza, to reach the town ofBethal, which marks the end of section 3 of the proclaimed N17 route. North of Bethal town centre, the N17 meets theR35 andR38 routes and they become one road southwards through the town centre (Moses Kotane Street) for a few kilometres. At Bethal Police Station, the R38 becomes its own road south-west and in the southern suburbs, the R35 becomes its own road southwards.[1]
From the R35 split in Bethal, the N17 goes eastwards for fifty kilometres to the city ofErmelo, which marks the end of section 4 of the proclaimed N17 route. Approximately 13 kilometres before Ermelo is the last N17 toll plaza (Ermelo Toll Plaza).[1] As of 2015, plans are underway to find a route for construction in order for traffic to skip the town centre.[4][5][6][7]
In Ermelo Central, the N17 enters as Joubert Street and meets the north-eastern terminus of theR39 road before it reaches an intersection with theN11 national route (Kerk Street), just one kilometre north of the N11's intersection with theN2 national route terminus. The N17 joins the N11 northwards up to the junction with Fourie Street, where the N17 turns eastwards. The route continues towards the north-east, meeting the western terminus of theR65 road just after Ermelo Central. At the junction with the southern terminus of theR36 road approximately 7 kilometres from Ermelo Central, the N17 continues eastwards by way of a right turn.[1]
3 kilometers before the town ofWarburton, the N11 is joined by theR33 route eastwards and they are one road for 10 kilometers, bypassing Warburton, before the R33 becomes its own road southwards.[1]
The N17 continues eastwards to reach theOshoek border post withEswatini, marking its end. It becomes theMR3 road on the other side and proceeds throughNgwenya to the city ofMbabane (Eswatini's Capital City).[1]
The 5th and last section of the proclaimed N17 route, from Ermelo throughChrissiesmeer, Warburton andHartebeeskop to Oshoek is 123 kilometers. The total distance of the N17 national route fromJohannesburg is 330 kilometres (290 kilometers fromSprings).[1]
There were plans to extend the N17 (Section 1) westwards from its present terminus with theM11 at Wemmer Pan Road inJohannesburg toKrugersdorp.[8] This would have made it a much needed second link between theEast Rand andWest Rand (presently the main link is via theN12/N3/M2 andR41 Main Reef Road orR24 Albertina Sisulu Road).
As part of the infrastructure built for the Soccer World Cup in 2010, a small portion of the N17, Section 1 has been built, including an interchange with theN1 highway (Johannesburg Western Bypass) (north off-ramp and south on-ramp only). However, the N17 remains a dual carriageway road, and not freeway for this section. It runs for approximately 8 km from theM5 Baragwanath Road (Nasrec Road) north ofFNB Stadium and then sharply veers off its alignment to end at theKlipsruit Valley Road (M10) andSoweto Highway (M70) junction north ofSoweto.[9][8] Even though this short stretch of road is labelled as the N17 on road signage and on maps, there are no plans to build the remainder of the N17 in either direction.
