SR 520 - 148th Ave NE Interchange - Overlake Access Ramp - Project map

SR 520-148th interchange map

To improve traffic on SR 520 and 148th Avenue Northeast in Redmond, WSDOT will reconfigure the interchange, adding a new eastbound SR 520 ramp to southbound 148th Avenue Northeast and extending the existing eastbound ramp underneath 148th into the planned Overlake Village area. The extended ramp also will serve the new Sound Transit light rail station that will be built nearby, just south of SR 520 between 148th and 152nd avenues. Interchange design work begins in 2019; construction is scheduled to start in 2021.
