Werrington Arterial Road Upgrade, Australia


Werrington Arterial

The Werrington Arterial road upgrade project is intended to create a new link between the Great Western Highway and the M4 Motorway in Australia. The project will improve access to the M4 Motorway and the road capacity, in addition to safety for motorists. It will also reduce the travel times, and provide access and safety for pedestrians and cyclists through an off-road shared path.

The project aims to increase the speed limits between the Great Western Highway and Caddens Road to 80km/h, and between Caddens Road and Lansdowne Road to 70km/h, from the existing 60km/h.

Australia's Federal Government and New South Wales Government are jointly sponsoring the project, while Roads and Maritime Services will be the operator.

Details of the Werrington Arterial road upgrade project

The Werrington Arterial road upgrade project involves widening Gipps Street and Kent Road to four lanes between M4 Motorway and the Great Western Highway. It includes upgrading new eastbound entry and westbound exit ramps, as well as traffic lights for the M4 Motorway. The project includes upgrading the traffic lights of three intersections, namely Caddens Road, Fowler Street and Sunflower Drive.

The project also involves construction of a 3m-wide off-road shared path, which can be used by pedestrians and cyclists. The shared path also includes a new bridge on M4 Motorway. Each concrete bridge span used for the new shared pedestrian and 32m-long cycle path, and will weigh approximately 120t each. A 500t crane is required to lift the bridge spans into place. It also involves construction of 2m-wide shoulders, and noise wall on the western side of Gipps Street between Caddens Road and the Great Western Highway.

Bicycle and pedestrian crossings will be created at traffic lights, and provision will be made for six bus bays on both sides of Gipps Street and Kent Road as part of the project. The barrier on the Kent Road bridge will be upgraded and one extra lane will be built for two northbound and one southbound lane.
