Marshalls Creek Bridge replacement

Major work starts this month to deliver the new Marshalls Creek Bridge, improving journeys for the 20,000 vehicles travelling the Sturt Highway through Wagga Wagga every day. 

When complete, the project will deliver improved traffic flow by eliminating the bottleneck created at the existing bridge, while also providing safer pedestrian and cyclist access with a shared path on the southern side and a footpath on the northern side of the new bridge. 

Work will start with preparing the site, including site fencing and setting up heavy machinery.

The first stage of work will involve closing access to the Wiradjuri Walking Track under the bridge and establishing a pedestrian crossing on the Sturt Highway, managed with temporary traffic lights. 

Pedestrians and cyclists will be diverted to temporary traffic lights on the western side of the bridge that will stop traffic when activated to allow safe crossing of the highway. 

A pedestrian creek crossing will also be built to allow safe crossings over Marshalls Creek and will be situated on the northern side of the bridge.

Once the pedestrian diversions have been set-up, work will start to shift traffic onto the southern side of the bridge to allow the first section of the bridge to be demolished. 

During this work, a one-day closure of the highway will be required to set up the bridge for the next stage. 

Further information about the highway closure will be shared with the community in coming weeks.

Marshalls Creek Bridge is an existing two-way, two-lane access route for vehicles travelling on the Sturt Highway in Wagga Wagga. The bridge limits traffic flow, forcing vehicles to slow down through this section of the highway.

Transport for NSW is replacing the crossing with a wider, longer bridge to ease congestion and improve safety in the area. The Marshalls Creek Bridge replacement will:

• improve safety for all road users
• improve traffic flow and efficiency, reducing the bottleneck that occurs during peak times
• improve safety for pedestrians and cyclists.

The replacement bridge will be 30 metres long and 25.3 metres wide including:

• four 3.5-metre-wide traffic lanes
• two 2.5-metre-wide shoulders
• a 3-metre-wide shared path on the southern side of the bridge and a 1.8-metre-wide footpath on the northern side of the bridge
• upgraded bridge approaches and widened section of the Sturt Highway to four lanes

A $30 million roads package was announced by the former NSW Government in August 2018. The intent was to fund the widening of Marshalls Creek Bridge and upgrade two intersections on the Olympic Highway in Wagga Wagga.

Due to the rising costs of construction both projects cannot be funded under this commitment. The NSW Government has listened to the Wagga Wagga community and reprioritised Marshalls Creek Bridge replacement. The Olympic Highway intersection upgrades project will be put on hold until more funding is available.

The detailed design for the replacement bridge is now complete. 

The replacement bridge will be 30 metres long and 23.8 metres wide including:

• four 3.5-metre-wide traffic lanes
• two 2.5-metre-wide shoulders
• a 3-metre-wide shared path on the southern side of the bridge and a 1.8-metre-wide footpath on the northern side of the bridge
• upgraded bridge approaches and widened section of the Sturt Highway to four lanes

Work on water and electrical relocations is expected to be completed in July 2025. 

Major construction work on the bridge is expected to start in September 2025 and take about two years to complete, weather permitting.
