Lanes will close as workers finish new Nalley Valley viaduct

Staff writerJanuary 4, 2014 

Work continues Friday on ramps over the Nalley Valley, as the Washington Department of Transportation warned commuters of lane closures on state Route 16 Saturday and Sunday.


Work crews will continue putting the final touches on the new Nalley Valley viaduct in Tacoma this weekend, which means lane restrictions on state Route 16 Saturday through Monday.

Workers were to close all lanes of eastbound state Route 16 where it crosses Nalley Valley at 10 p.m. Friday. They also were closing the southbound Interstate 5 exit to South 38th Street.

Two lanes of eastbound state Route 16 and the exit were to reopen at 7:30 a.m. Saturday and stay that way until 10 p.m. when they would be closed again.

One eastbound lane should reopen at 11:30 a.m. Sunday, with traffic then detoured onto southbound I-5. Drivers wishing to go north on I-5 will be funneled to the South 56th Street interchange to change directions.

At 10 p.m. Sunday, it will all close again, with all lanes scheduled reopen at 4 a.m. Monday.

That’s when drivers will begin using the new, permanent eastbound viaduct for the first time. Drivers have been using a temporary span during the project to revamp the Nalley Valley structures.

Drivers can check for information and updates.

This weekend’s work includes painting lines on the new viaduct and moving concrete barriers, the state Department of Transportation reported. Next up for the viaduct-replacement project is finishing the ramps that will connect Sprague Avenue to both directions of I-5.

When the new eastbound bridge is in place, crews will knock down the temporary viaduct and keep building those ramps, which should be open to traffic in May or June.
