Needs & benefits

Travelers who use the interchange of SR 161 and SR 512 in Puyallup experience regular congestion during peak commute hours. This project adds a new signal and an additional right turn lane to the eastbound SR 512 exit to SR 161. It will also restripe the SR 161/31st Avenue Southwest overpass to extend the right turn lane to westbound SR 512. This will allow more vehicles to use the turn lane. This project is implementing some of the short term improvement strategies identified in the SR 161 - 31st Avenue SW Corridor Study, conducted by the city of Puyallup and WSDOT.

The study used a practical solutions approach to help identify ways to reduce congestion and improve traffic operations at this interchange.
