Description: The City of Sumner is proposing to add general purpose lanes and non-motorized facilities on Traffic Avenue between the five lane, E. Main Street Bridge, over the Puyallup River and the five lane section of Traffic Avenue extending north towards downtown Sumner. The most significant section of work will include adding a lane in each direction to the existing two lanes bridge crossing over SR410. This would be done by building a separate parallel structure to carry new general purpose lanes and non-motorized facilities. The project will reconfigure intersections at each end of the existing SR410 overpass that connect to the SR 410 access ramps and Thompson Street. The south end of the project will connect to Puyallup’s Riverwalk Trail, the Sumner Link Trail, and Pierce County’s Foothills Trail system. Non-motorized facilities will be installed through the length of the project to provide an ADA accessible pathway connecting to the Sound Transit Sounder Rail Station.
