To reduce chronic congestion around Northup Way and 124th Avenue Northeast, which can make it take longer to get on or off State Route 520, Bellevue will add lanes to both streets.
The project is set to begin on Monday, March 30, and conclude in December. Over that time, lane closures will be required at various times on both Northup Way and 124th Avenue, as well as the 520 on- and off-ramps.
Construction will be 7 a.m. to 6 p.m. Monday through Friday, with lane closures from 8 a.m. to 3:30 p.m.
The $3.6 million Northup Way Corridor project will add:
- an eastbound lane on Northup Way, between 120th and 124th avenues Northeast;
- a left-turn lane from eastbound Northup Way to the SR 520 on-ramp; and
- a right-turn lane on northbound 124th Avenue;
In addition, new curbs, gutters and sidewalks will be installed, traffic signal modifications and storm drainage improvements will be made, and retaining walls and landscaping will be added.
In August, crews close 124th Avenue Northeast to through traffic in both directions for two weeks to regrade the roadway.
Travelers should be prepared for delays in that area. Those who must pass through the construction zone should watch for flaggers and obey posted construction signs.
After the Northup Way Corridor project is completed, the state Department of Transportation will improve the transition from northbound I-405 to eastbound SR 520, and the exit from SR 520 to 124th Avenue Northeast.
