The Triangle Project at State Route 18 and Interstate 5 will reach a milestone this weekend as crews begin the first of three major weekend-long closures to set girders across I-5.

Crews must close all lanes of southbound I-5 on Friday and Saturday nights, Feb. 10 and 11. Crews will begin closing lanes at 9 p.m. with all lanes closed by 11 p.m. Lanes will reopen by 7 a.m. the following day. The closure will affect thousands of southbound I-5 and westbound SR 18 drivers.

Overnight travelers should add an extra 30 minutes to their trip. The five-mile signed detour will direct drivers onto South 348th Street to Highway 99, then to 54th Avenue East in Fife to rejoin southbound I-5.

This work is part of the $112 million Triangle Project to build two new flyover ramps: one between westbound SR 18 and southbound I-5, and the other between eastbound SR18 and northbound I-5. The ramps are expected to open this summer.
