SR 520 148th Ave NE interchange - Overlake Access Ramp

Project overview

With this Connecting Washington project, we will relocate the existing eastbound SR 520 ramp to south 148th Avenue Northeast in Redmond and add a new eastbound ramp to the Overlake Village area.

Summer 2021-Fall 2023
Project status
$68 million

What to expect

During construction, people traveling in the area should expect closures and lane reductions on the off-ramp from eastbound SR 520 to 148th Avenue Northeast. There will be lane reductions on 148th Avenue as our contractor builds a tunnel under the roadway to improve access to the Overlake Village area. 

On eastbound SR 520 exit to 148th Avenue Northeast, we will realign the existing ramp and add a ramp underneath 148th  to the Overlake Village area.
