166th Avenue E/SR 410 Interchange


The Challenge

The State Route 410/166th Avenue interchange is a congested mess. Originally built in the early 1970s, this interchange serves regional commuters cutting through Sumner to avoid the SR 167 congestion and thousands of vehicles trying to access busy commercial areas. Beyond the usual congestion found at so many regional interchanges/routes, the issue here is a completely unsafe intersection control situation for drivers, as well as a complete lack of pedestrian facilities and a small, buried culvert that prevents fish from continuing to access habitat in Salmon Creek.

Solutions

  • Widen the remaining two-lane stretch of 166th Avenue to eliminate the bottleneck just north of the existing SR410 interchange.
  • Design and construct a signal at the existing stop-controlled SR410 Westbound on/off ramp.
  • Replace an existing undersized culvert with a new fish-passage culvert to carry Salmon Creek across the existing intersection at 166th Avenue and 64th Street. Daylight a portion of stream channel to improve salmon habitat.
  • Interconnect existing traffic signals together and with new signal to reduce congestion and improve safety.
