OR 126B: Westbound Main Street Bridge Repairs

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Springfield, Lane)

We're repairing this historic bridge to keep it in good working order and give you a smoother ride.

Banner: Slow down, in the work zone it could save lives. Building a modern transportation system to help Oregon’s communities and economy thrive. During construction, Give yourself more time, try a new way or mode to get there or take a different route.

Impacts

Traffic Impact

Expect construction noise and delays. Please use caution and watch for workers.

Construction Impacts

You can expect:

Crews working mostly during the day, 7 a.m. to 5 p.m.
Lane and shoulder closures as needed.
Flaggers directing traffic when crews are setting up cones and barrels.
Construction noise and delays.
Businesses to remain open during construction.
A three-week-long 24/7 full bridge closure with detours in early January 2026.

During the closure, you can expect:

Both directions of traffic to use the South A Street Bridge.
A new temporary connection from South A Street Bridge to the roundabout for westbound traffic.
A new temporary traffic pattern in the roundabout with lane closures to ensure that traffic can use it safely.
Pedestrians and bicyclists to use South A Street Bridge.

Local freight and passenger vehicles can use South A Street Bridge or detour around the work zone using Pioneer Parkway and OR 126. Larger freight and oversized vehicles can use OR 126 / Bob Straub Parkway to get around the Main Street Bridge closure.

Construction Activities

Crews are prepping for the early 2026 detour.

Visit TripCheck for the most current traffic information.

Pedestrians, including those with disabilities, will have access through or around work zones.

Pay attention in the work zone, slow down and move over – imagine this is where you work!

Always drive safely, watch for construction signs and workers.

Remember: fines double in all Oregon work zones, whether workers and signs are present or not.

About

The historic westbound OR 126B Main Street Bridge over the Willamette River was built in 1929. The surface has cracks and is in need of repairs.

To improve the bridge's lifespan, we're:

Removing and replacing the bridge surface.
Replacing the bridge joints.
Repaving the road on the east approach.
Adding a bike ramp at the east approach.

During construction, we're considering a full bridge closure and would detour both directions of traffic to share the South A Street eastbound bridge.

We're planning to build and will have a better idea about construction schedule and cost as we get further into design.
