SR 522 Bothell Crossroads

Summary

The heart of Bothell, northeast of Seattle, is two intersecting highways which carry 44,000 vehicles each day. It has a charming downtown and a lovely nearby riverside park. But the grid simply didn’t work for anyone – not drivers, not residents, and certainly not the city. The City of Bothell partnered with WSDOT, Perteet and Greenroads to take it down to the studs and start over.

Description

The SR 522 Bothell Crossroads Project realigns SR 522 through the historic center of Bothell to the south of the previous alignment, extending from Hall Road at the western end of the project area to 102nd Avenue NE on the eastern end. The project includes intersection upgrades and small block-length extensions at SR 527 (Bothell Way NE), 180th Street, and 98th Avenue. This project reduces regional and local congestion, improves safety, improves downtown circulation and enhances livability and walkability of the area. Additionally, the project will stimulate economic redevelopment along the SR 522 corridor.
