This is the final weekend of six weekend closures for the state Route 520 bridge approach panel repair work.

Once the work is complete, crews will shift to nighttime closures as they repave four miles of SR 520 between I-405 and West Lake Sammamish Parkway. It is hoped this work will extend the life of the roadway and make the ride much smoother.

This weekend contractor crews in Bellevue will replace worn-out bridge approach panels just east of I-405.

• From 11 p.m., Friday, April 24, through 5 a.m. Monday, April 27, crews will close two of four lanes of westbound SR 520 from 124th Avenue Northeast to I-405.

• The right lane is dedicated to the westbound SR 520 ramp that goes to I-405. The left lane is dedicated to through traffic.

• The 124th Avenue Northeast on-ramp to westbound SR 520 will be closed all weekend.

• WSDOT is working with the city of Bellevue to maximize signal timing on city streets to keep traffic moving.

This $9 million project involves 16 Washington companies.
