Construction this week on the new Tacoma Narrows Bridge:
Anchors: Crews are nearly finished placing the anchors that will hold the bridge caissons in place. As of Friday, they had placed 58 of the 64 anchors. They expect to finish them June 24.
Caissons: At the Port of Tacoma, crews have two more concrete pours to go before the Tacoma-side caisson is ready to tow to the bridge site. That should happen July 21. The Gig Harbor-side caisson will follow about a month later.
Roadwork: In response to requests from Gig Harbor residents, Tacoma Narrows Constructors, the bridge builder, has pushed the schedule forward on the westbound on-ramp to Highway 16 at 24th Street Northwest. The on-ramp now is to be finished at the same time as the rest of the 24th Street project - in late September.
Q: When is the second half of the new overpass at 24th Street going up?
A. TNC says it will start hoisting the six girders for the western side of the 24th Street overpass on Friday. These girders are smaller - 114 feet long and 119,000 tons each, compared with 140 feet and 150,000 pounds on the eastern side. So, lifting them into place won't be as big a production as were the girders for the eastern side. TNC crews will use just one crane instead of two, and, because the span doesn't cross traffic, Highway 16 won't be shut down.
Look for lane closures Wednesday, Thursday and Friday nights between the Gig Harbor end of the bridge and 36th Street Northwest. Crews will be restriping the roadway and extending a concrete barrier 3,000 feet so they can start building a westbound on-ramp from the 24th Street interchange. Work hours will be 11 p.m. to 7 a.m.
