VANCOUVER, Wash. (KOIN) — This weekend, Washington Department of Transportation crews will install 12 girders in the last phase of the Salmon Creek Interchange Project, totally closing a section of Interstate 5 for days.
Southbound I-5 will be closed between I-205 and NE 134th Street, and northbound I-5 will be closed between SR-500 and I-205.
The primary detour will be I-205.
Moving the girders is risky and it takes time.
“One of the reasons we have to do the closure is because we will have a crane sitting in the middle of the freeway,” said WSDOT project manager Allen Hendy. “This particular geometry here of the project requires three cranes in order to set the girders.”
Each girder weighs 175,000 pounds, is 165 feet long and about six feet tall.
That section of I-5 will be closed beginning at 11 p.m. Friday and will re-open at 5 a.m. Monday.
