TACOMA – State and local officials gathered to commemorate the near completion of a three-year highway construction project in the heart of Tacoma. The Eastbound Nalley Valley project is the second of three projects that will help reduce collisions and congestion near the Interstate 5/State Route 16 interchange.
“Today’s ceremony highlighted the hard work and dedication of the many skilled workers who built several new bridges and demolished an aging 44-year-old viaduct,” said Washington State Department of Transportation Administrator Kevin Dayton.
Recently, crews opened a new ramp from eastbound SR 16 to the northbound collector/distributor leading to downtown Tacoma and northbound I-5. In about three weeks, crews will open the final two ramps in the project that lead from South Sprague Avenue to northbound and southbound I-5. In total, crews built five bridges with more than 50,000 cubic yards of concrete and about 8.4 million pounds of steel.
The first project in the three-project I-5/SR 16 interchange improvement plan was a new westbound viaduct that opened to traffic in June 2011. With the completion of the second project, the eastbound viaduct, the stage is now set for the third and final phase of construction in which crews will build a separate bridge to carry HOV traffic and HOV ramps between I-5 and SR 16.
This $114 million project is a piece of the overall effort to build HOV lanes on I-5, SR 16 and State Route 167 in Pierce County.
