The state Department of Transportation announced today that it awarded a $74.7 million contract for work on the eastbound section of the Nalley Valley viaduct.
Mowat Construction Company of Woodinville is expected to begin work this fall on a new eastbound state Route 16 viaduct; the project also will include new ramps from Sprague Avenue to northbound and southbound Interstate 5.
Construction is scheduled to continue through spring 2014. The eastbound work follows the June opening of new approaches from I-5 to westbound Route 16, a westbound viaduct over Nalley Valley and off ramps to Sprague Avenue.
In this next phase, the remaining sections of the original 1971 Nalley Valley viaduct will be demolished. State officials say drivers can expect lane and ramp closures on I-5 and Route 16, two extended closures of I-5 ramps near the Tacoma city center, and some total highway closures for demolition and bridge building.
