Birch Bay-Lynden Road repairs begin

Crews have begun repairs to the Birch Bay-Lynden Road I-5 overpass.

The overpass was damaged last May  when a transporter loaded with an excavator clipped the underside of the overpass. One support girder was seriously damaged while another suffered minor damage. The overpass has been operating with reduced lanes since the accident.

Washington State Department of Transportation (WSDOT) crews will be replacing the 60-foot girder on the underside of the bridge.

“The crews will cut out a piece of the existing bridge with the damaged girder,” said Jason Koreski, project engineer for WSDOT. “We’ll then replace the old girder with a new one before pouring a new concrete deck to connect the bridge again.”

Traffic on the overpass has been reduced to one lane of alternating traffic. Flaggers will direct traffic during peak travel hours, and a temporary signal will be used outside of peak hours.

Some of the work will require occasional nighttime closures of both southbound lanes of I-5 near exit 270. At those times, southbound drivers will be instructed to exit at Birch Bay-Lynden Road and immediately access the south entrance to I-5.

WSDOT representatives expect construction will be complete by April, barring any delays for severe weather conditions. Follow up on the project’s progress at wsdot.wa.gov.
