Construction this week on the new Tacoma Narrows bridge:
Heavy rain last week made a mess in several parts of Tacoma Narrows Constructors’ work area, especially at the new Jackson Avenue on-ramp, where a part of the pavement was undercut.
Also, TNC had to pump excess runoff into the Tacoma Narrows on the Tacoma side, meaning environmental citations from the state Department of Ecology.
This week the bridge builder will be mopping up and getting ready for the next storm.
From 7 p.m. Wednesday through 5 a.m. Thursday, road crews will shut down the left lane on eastbound Highway 16 for erosion-control activities.
Despite the bad weather, bridge crews managed to get deck section No. 44 pinned to No. 45 on the Tacoma side. This week they’ll start trapezing No. 43 in toward the east shore.
They’ll also be setting one of their mobile temporary access gantries – “M-tag,” for short – beneath deck sections on the east-side span, and they plan to start permanent welding on deck sections on the west-side span.
Road crews will be putting down crushed base-course rock in the median area of Highway 16 on the Gig Harbor side near the 36th Street ramp.
The transport vessel Swan, carrying the last 15 of 46 deck sections from South Korea, is more than a third of the way to Tacoma. It should be here by Thanksgiving, weather depending.
