Summer light rail construction requires detours in Milwaukie


Crossing construction begins June 24 and includes new sidewalks, rail and roadway improvements; an important step towards establishing a quiet zone for train operations in the area

Over the summer, Portland-Milwaukie Light Rail Transit Project construction will require temporary road closures and detours at a series of rail crossings in downtown Milwaukie. The construction includes installing wider/new sidewalks and roadways, installation of light rail tracks and upgrading underground utilities. It will also result in safety improvements to the rail crossings that will allow the City of Milwaukie to apply for a quiet zone where train horns will only sound if there is an immediate safety issue.

Further safety improvements at each rail crossing will be installed by the light rail project as the project progresses; these improvements are necessary for the City to acquire approval of their Quiet Zone application. Once approved and all safety measures are in place, the quiet zone operation would go into effect prior to the start of light rail train service in September of 2015.
