Springfield Main Street Bridge Partial Closure Begins for Repairs

Oregon Department of Transportation crews began work Jan. 5 on the westbound Main Street (Highway 126-B) bridge over the Willamette River in Springfield, initiating a closure that will last about three weeks. The project packages repaving, bridge repairs and installation of a new bike ramp; a full closure for the westbound span will let crews work more quickly and safely.

Because the closure requires rerouting traffic, both directions of vehicle traffic will be diverted to the South A Street bridge using a temporary connection to the Franklin Boulevard roundabout. Motorists should expect daytime lane and shoulder closures and travel delays while crews are on site, with traffic controls in place to manage flows across the alternate crossing.

The work affects commuters, school runs and commercial traffic that use Main Street as a primary east-west route through Springfield. Drivers who cross the Willamette River near downtown are likely to encounter longer travel times and should allow additional time for trips or consider alternate routes. Cyclists and pedestrians will see short-term inconvenience while the bike ramp is built, but the project aims to improve access and safety for nonmotorized users once complete.

Local businesses near the bridge and along detour routes may experience changes in customer traffic patterns during the work. Emergency service routing and public transit schedules can be affected by lane restrictions and detours; agencies and drivers will need to coordinate around the temporary traffic pattern as crews progress. Daytime work means primary impacts will occur during peak travel hours, though night work was not indicated.

The project highlights the balance between short-term disruption and longer-term infrastructure benefits. Repaving and structural repairs extend the service life of a critical crossing of the Willamette River, while the new bike ramp supports local efforts to expand active transportation options in Springfield.

Residents and regular users of Main Street should follow posted detour signs and plan for delays through the three-week work window. Traffic control will remain in place while crews complete the repairs and the new bike ramp, after which the bridge will return to normal operations.
