SEATAC – For the second weekend in a row Tri-State Construction crews working for the Washington State Department of Transportation will close southbound I-5 between the I-405 interchange and S. 188th Street. The closure will allow crews to install a new girder in place of the damaged bridge girder they removed last weekend.
“Last weekend’s work went smoothly,” said WSDOT Project Engineer, Mike Askarian. “We were able to open lanes about a half an hour early and traffic moved through the detour route with minimal delays. We hope to have similar success this weekend.”
Crews will start closing lanes at 7 p.m. Saturday night, March 1 with all lanes of southbound I-5 closed by 11:59 p.m. Traffic will follow the same detour as last weekend, taking southbound I-5 onto northbound I-405 to southbound SR 167 to westbound SR 516 and then back onto southbound I-5. Crews will swing the new girder into place during the total closure of I-5. They will start reopening lanes to traffic once the girder is secured in place around 6 a.m. Sunday, March 2. All lanes will reopen to traffic by noon on Sunday.
Drivers should expect delays on southbound I-5 approaching the closure and also on southbound SR 167. Travelers heading south from SeaTac Airport should use SR 99. Travelers on southbound I-405 and southbound I-5 will still be able to access the airport using SR 518.
Crews will also close S. 178th Street over I-5 from 10 p.m. Saturday to 8 a.m. Sunday morning. Drivers wishing to travel over I-5 should look for and follow detour signs.
The S. 178th Street overpass was damaged when a vehicle exceeding the height limit on I-5 struck the overpass on Dec. 13, 2006. Since then bridge engineers have narrowed traffic lanes across the overpass to prevent further damage and keep drivers safe while they planned repairs. Repair work will continue on the S. 178th Street bridge deck through May 2008.
