Construction this week on the new Tacoma Narrows bridge:
Both bridge towers will pass the 310-foot mark this week, with pours scheduled for Monday, Thursday, Friday and Saturday.
The top will go on the Gig Harbor anchorage this week. Wednesday, crews will set a dozen 66-foot-long girders on top of the side walls. Thursday, they’ll set two box girders on either end. The girders are made of prestressed concrete and will be lifted into place with a crane.
On the Tacoma anchorage, the girders are already in and crews will work on stiffening diaphragms in preparation for pouring the top layer of concrete.
Watch for nighttime lane closures on Highway 16 throughout the construction area.
Crews will be cleaning dirt off the roadway and installing reflectors on barriers. From midnight to 7 a.m. Tuesday, one westbound lane will be closed from the weigh station in Gig Harbor across the bridge to Tacoma’s Jackson Avenue.
Thursday, one eastbound lane will be closed on the same stretch for about four hours beginning at 9 p.m.
A section of the new toll plaza, near 36th Street Northwest, will be paved Friday, weather permitting.
The public is invited to an open house from 6 to 9 p.m. Tuesday at Tacoma Alliance Church, 2401 S. Orchard St. Representatives of the state Department of Transportation and Tacoma Narrows Constructors will show displays and computer simulations and answer questions. Rob Carson, The News Tribune
