Highway system

The Port River Expressway is a 5.5-kilometre (3.4 mi) freeway-grade road. The expressway links Port Adelaide and the LeFevre Peninsula to the northern suburbs of Adelaide and major interstate routes via Salisbury Highway (A9) to Port Wakefield Road (A1) and the Max Fatchen Northern Expressway (M2) to Perth, Darwin and Sydney.

The expressway is only grade-separated at the North-South Motorway, Hanson Road and Eastern Parade interchanges; the following two intersections are at grade with traffic signals installed. This has led to the route being labelled as the A9, instead of the more common M label associated with freeways and expressways in South Australia.

Construction[edit]

The Port River Expressway was built in three stages:

  • Stage 1 - Was opened for traffic on 19 July 2005. It consists of a 5.5-kilometre (3.4 mi) four-lane expressway link between Francis Street and the then South Road, Adelaide, now North-South Motorway; with an overpass at each of the junctions of the North-South Motorway, Hanson Road and Eastern Parade.[1]
  • Stage 2 - Consists of a four lane high-level, opening road bridge across the Port River between Docks 1 and 2, linking Stage 1 at Francis Street to Victoria Road on Le Fevre Peninsula. This section opened on 3 August 2008[2]
  • Stage 3 - Consists of a single track, dual gauge, high-level, opening rail bridge across the Port River, north of the road bridge, with connections to the existing rail system. Opened in June 2008.[3]

Stage 1 connected at what had previously been a bend between extensions of South Road and Salisbury Highway both of which had been extended in the early 1990s to meet each other. The original plan had been to install traffic lights at that intersection. Instead, an overpass was constructed with a loop through the Barker Inlet wetlands to provide a non-stop interchange. The bridge (for traffic travelling north on South Road to east on Salisbury Highway and east on Port River Expressway to south on South Road) was named the Craig Gilbert Bridge. Craig Gilbert had been the lead designer of the overpass, but died of cancer before it opened. The bridge was opened and named in his honour on 19 July 2005.[4] It was closed and demolished in May 2019 as part of the construction of the Northern Connector which included new wider bridges on a slightly more westerly alignment.[5]

The Port River Expressway is now a major thoroughfare for freight and passenger road traffic travelling from the northern suburbs to the major port facilities of South Australia in Port Adelaide and Outer Harbor. The construction of Stages 2 and 3 was carried out by Abigroup.[6]

During 2018 and 2019, construction workers were putting up new elements on the expressway, as part of the Northern Connector project.

Cycling[edit]

As there is no parallel shared path near most of the Expressway and Salisbury Highway west of Port Wakefield Road, cycling is permitted on the road, except for restrictions due to closed road shoulders during construction of the Northern Connector from 2017 to 2019.[7][8] Parts of the detour route were new shared paths constructed or upgraded in anticipation of this detour.[9] The bridge over the Port River includes a shared path on the southern side of the road as part of the construction.[10]

At the time of designing Stage 1 of the Expressway, the developers did not imagine that there would be much requirement for people to cycle along it, as Mawson Lakes had not been developed for housing yet, so the Port River Expressway was seen as only connecting industries to other industries.[11]

A new path parallel to the Port River Expressway will be built as part of the Northern Connector works. This will complete a shared cycling and walking track between Gawler and Port Adelaide by the end of 2019. As a result, cycling will then be banned on the Port River Expressway itself.[12]

Exits and interchanges[edit]

The entire road is in the City of Port Adelaide Enfield local government area.

The Port River Expressway lies in a corridor that links predominantly industrial areas to industries in the Outer Harbor area (its principal purpose being to link national roads with the industrial areas of Wingfield, Enfield and Gillman). This means that bicycle paths provided in the shoulders of the Port River Expressway are not likely to be used primarily for commuting.
