Project Alert

Westbound Main Street Bridge closure starts December 1

Progress of building the detour road for the OR 126B bridge closure gif

Plan ahead – full bridge closure starts December 1

We're closing the westbound OR 126B Main Street Bridge so we can 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, 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.

During construction, you can expect:

Crews mostly working during the day.
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 full bridge closure with detours.
