SE Monroe Street in downtown Milwaukie to be closed 3 weeks for light rail construction


August 5-25 construction requires detours; weekend McLoughlin closure in mid-August

The Portland-Milwaukie Light Rail Transit Project construction will require a temporary three-week road closure of SE Monroe Street between SE 21st and 25th avenues in downtown Milwaukie. Beginning at 7 a.m. on Monday, Aug. 5 through 7 p.m. Sunday, Aug. 25, construction crews will install a new storm water line and light rail tracks, as well as heavy rail tracks for the Portland & Western Railroad.

When all light rail construction at crossings in downtown Milwaukie is complete, the crossings will have safety features that make them eligible for quiet zone implementation. In a quiet zone, freight and light rail trains will only sound their horns at crossings if there is an immediate safety issue.

Construction hours
Throughout all phases of construction, retaining local access to businesses and residences is a top priority for TriMet. Construction work hours will be Monday through Friday, 7 a.m. to 7 p.m., and Saturday and Sunday, 8 a.m. to 5 p.m. However, the closure does remain in effect around the clock.

Detour Information
Local access for businesses and residences within the closure area will be maintained at all times. For detour information and maps, visit
