Project overview
With this Connecting Washington project, we made multiple improvements to the State Route 520/148th Avenue Northeast interchange within the cities of Bellevue and Redmond.
Our contractor, Granite Construction, built a direct-access off-ramp from eastbound SR 520 to the Overlake Village area in Redmond through a tunnel running beneath 148th Avenue Northeast. The project also built two roundabouts and the new Redmond city streets of Northeast Hopper and Northeast Shen streets and Lumiere Avenue.
The direct-access ramp bypasses the busy 148th Avenue Northeast/Northeast 24th Street intersection, where traffic routinely backed up during peak travel times, and establishes a direct route to destinations along 152nd Avenue Northeast and beyond.
What to expect
Construction finished in early December 2023. Intermittent closures at the SR 520/148th Avenue Northeast interchange are possible into spring 2024 for final landscaping.
On eastbound SR 520 exit to 148th Avenue Northeast, we realigned the existing ramp and added a ramp underneath 148th to the Overlake Village area.
The eastbound SR 520 off-ramp to 148th Avenue Northeast in Redmond's Overlake area regularly had heavy congestion and drivers weaving across 148th to reach Northeast 24th Street and other left turns.
With the arrival of Sound Transit light rail, traffic will likely increase in the Overlake area. The city of Redmond has infrastructure improvements planned for the Overlake Village area. The new ramp under 148th to the Overlake Village area will provide another option to reach that area and reduce congestion on the SR 520 off-ramp.
When work is complete, people will have direct access to Overlake Village from SR 520. We also worked with the city of Redmond on new city street connections and Sound Transit's new Overlake Village Light Rail Station.
