Project alert

Westbound Main Street Bridge closure starts early 2026

Heads up Springfield – our schedule has changed

We originally planned to start the full closure of the OR 126B Westbound Main Street Bridge on December 1, 2025, but our schedule has changed.

We heard you – any delays caused by weather could impact holiday travel, so instead of starting work this year we're now planning for the full closure to start in early January 2026.

This temporary full bridge closure next year will allow us to make repairs, replace bridge joints and install a new bike ramp. We'll also repave a section on the east side of the bridge. Temporarily closing the bridge helps us complete this work faster in a safer work zone.

During the closure early next year, 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.

Businesses to remain open during construction.
A three-week-long full bridge closure with detours.
