Construction this week on the new Tacoma Narrows bridge:
Crews will embark on an “aggressive” deck-lifting schedule this week, said Claudia Cornish, a state Department of Transportation spokeswoman.
They will try to move three deck sections from the transport ship Teal into place in the suspender cables before the week is through, she said.
The process entails moving the sections from the Teal to a barge. The barge then will motor under the proper part of the bridge, where powerful cranes mounted on the span will lift the sections into place.
Crews also will use a complicated technique called “trapezing” to swing two sections into place on the extreme eastern and western ends of the bridge, Cornish said.
Workers will be busy on the approaches to the bridge as well, Cornish said. They will be paving ramps at the new 24th Street interchange as well as future eastbound lanes on the Tacoma side.
Excavation crews also will be working on an embankment on the Gig Harbor side, and other workers will continue the seismic retrofitting upgrades on the east end of the existing bridge, Cornish said.
