Construction this week on the new Tacoma Narrows bridge:
Old War Memorial Park used to be under the Tacoma end of the Tacoma Narrows Bridge.
Work on the park’s replacement begins this week along Interstate 5 near the eastbound Jackson Avenue on-ramp. Watch for brush cleaning and grading. (The old park now lies beneath the east anchorage for the new bridge.)
Work on the bridge towers is proceeding more slowly now that crews are so close to the top.
The final two sections of the tower legs are complex and labor-intensive because they contain so many connections for the top strut and cable-spinning equipment, all of which must be precisely aligned.
Tacoma Narrows Constructors schedule calls for topping out the towers by the end of this month.
The forms are off the middle strut on the Gig Harbor tower. The post-tensioning crew will finish up there this week. The middle strut on the Tacoma tower is nearly finished. Crews will pour the top slab and the parapet walls this week.
A heavy-duty crane is coming to the Gig Harbor anchorage early in the week to lift the main cable saddles into place on top of the anchorage. The Tacoma anchorage saddles are already in place.
What is that big steel frame that stretches across the all the new lanes in front of the toll plaza?
That’s called a gantry, and it will be used for signs directing drivers into the proper lanes as they approach the toll booths.
