Bridge Update

Construction this week on the new Tacoma Narrows bridge:

Barring unforeseen problems, crews should finish removing the false bottoms from the Gig Harbor caisson by the middle of the week.

They'll then begin slow, deliberate dredging of material from the bottoms of the 15 shafts, easing the caisson 57 feet into the sea floor.

On the Tacoma caisson, there will be one concrete pour Tuesday, then crews will begin removing form work so the false bottoms on that side can be cut out.

One concrete pour - a huge one, 2,100 cubic yards - is scheduled on the Gig Harbor anchorage this week, on Wednesday.

No pours on the Tacoma anchorage this week. Tacoma Narrows Constructors is getting ready to install large steel anchor plates that will be delivered to the site by truck on March 11 and 12.

Roadways: Expect nightly single-lane closures on both sides of the bridge so crews can work on drainage facilities near the concrete plant.

Eastbound closures will occur between 7 p.m. and 5 a.m.; westbound closures will be between 9 p.m. and 7 a.m.

Look for lots of work and heavy equipment in the median of Highway 16 near the bridge on the Gig Harbor side.

Crews are grinding down old pavement, getting ready to build a retaining wall that will support the elevation change between eastbound and westbound lanes.



Q&A



Q: When is 22nd Street Northwest in Gig Harbor going to reopen? It's my favorite shortcut.



A: April 3, the Department of Transportation says. Road crews will be forming curbs and doing more paving there this week. You still won't be able to get on and off the bridge there, though.

Connections to the 36th Avenue Northwest ramps probably won't open until May.
