Tacoma Area Construction

Relocating I-5 in Tacoma a major effort that requires significant lane reduction

Trying to accommodate 197,000 vehicles a day while building the most substantial overhaul of Interstate 5 in Tacoma since the highway was first opened in the 1960s is, to put it mildly, a challenge. We've asked for a lot of patience from drivers this summer. We've had overnight closures, full weekend lane closures, and many ramp closures and detours. Your cooperation during those temporary lane restrictions have helped construction move forward. We need your help once again as we move into a new phase of building HOV lanes through Tacoma on I-5.

Crews are building a new path for northbound I-5 in Tacoma

Work continues for I-5 HOV projects in Tacoma

Lane closures
Drivers may encounter single- and double-lane closures in both directions of I-5 between Port of Tacoma Road and M Street.

Ramp closure through September
Southbound I-5 exit to southbound State Route 7 is closed around the clock to all vehicles through the end of September. The closure is associated with the continued demolition of the East McKinley Way overpass.

New Pacific Avenue overpass opens in Tacoma,  East McKinley Way overpass closed

A key route into and out of downtown Tacoma is now open. The new Pacific Avenue bridge at Interstate 5 has opened to one lane of traffic in each direction. The overpass is also open for use by bicyclists and pedestrians. Crews will continue work to complete the overpass. The bridge ultimately will have a four-lane configuration, a 6-foot-wide sidewalk and a 14-foot-wide shared-use path. 

At the same time, East McKinley Way at I-5 is closed to all traffic. The closure will allow crews to demolish and rebuild the overpass. The closure will be in effect around the clock and is expected to last up to 18 months. During that time, drivers, bicyclists and pedestrians will detour to Pacific Avenue.

Rebuilding the overpass is part of the effort to expand I-5 HOV lanes into Tacoma.
