I-5 - SR 16 Realignment - HOV Structure and Connections - Project map

To increase safety, improve mobility and reduce congestion, WSDOT is rebuilding the entire I-5/SR 16 Nalley Valley interchange. The HOV Connector project will build new bridge structures and direct-access ramps to connect I-5 HOV lanes to SR 16 HOV lanes.

Eastbound SR 16 to S. 38th Street West Detour

In May, crews will move southbound I-5 into a temporary configuration. Eastbound SR 16 travelers will not be able to exit to South 38th Street west. Drivers will be directed via southbound I-5 and exit at South 56th Street, and will be routed back north to westbound South 38th Street. See detour map below:

Detour map for eastbound SR 16 drivers going to South 38th Street west.


During this temporary lane configuration, drivers heading to southbound I-5 from I-705, SR 7 and Pacific Avenue will be directed onto the South 38th Street exit, and will rejoin southbound I-5 near South 48th Street via the collector/distributor.

South Tacoma Way Detour
In March, contractor crews installed 9 girders, safety deck and overhangs on the new SR 16 HOV structure that will connect with I-5 HOV lanes. This work required closing South Tacoma Way between S. Pine Street and S. Wilkeson Street during overnight hours. Additional overnight closures of South Tacoma Way will be scheduled as work progresses. During the closures, local access will be allowed on South Tacoma Way between S. Sprague Avenue and S. Pine Street. South Tacoma Way will reopen during daytime hours. 

Closure hours:

  • Sunday - Thursday from 9 p.m. to 4 a.m. each following day
  • 11 p.m. Friday to 7 a.m. Saturday
  • 11 p.m. Saturday to 9 a.m. Sunday
