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.

Temporary ramp closures and detours

South Sprague Avenue on-ramp to southbound I-5

In 2019, eastbound SR 16 drivers headed to southbound I-5 will temporarily relocate to the newly-built SR 16 HOV lanes. This change will affect South Sprague Avenue travelers going to southbound I-5.

South Sprague Avenue drivers will use the following detour:

  • South Sprague Avenue to southbound I-5 will detour to westbound SR 16, South Union Avenue and back to eastbound SR 16 to continue on southbound I-5.

The South Sprague Avenue to southbound I-5 detour will be in place until the South 38th Street east loop ramp reconfiguration is complete.

Southbound I-5 to South 38th Street east loop ramp

In early 2019 design-builder Skanska will modify the existing Interstate 5/South 38th Street interchange to allow right- and left-turns at the top of the loop ramp. To enable this change, the South 38th Street east ramp will close to all traffic for 30 days. During the closure, the following detours will be in place:

  • Eastbound SR 16 drivers going to South 38th Street east or west will detour to South 56th Street to northbound I-5 to exit 132.
  • Southbound I-5 drivers going to South 38th Street east will detour to South 56th Street to northbound I-5 to exit 132.

The southbound I-5 exit 132A to South 38th Street west will not be affected.

Once work is complete, South 38th Street will have a new traffic signal that allows eastbound and westbound access to all drivers. This temporary configuration will remain in place through the end of the project.

South Tacoma Way Detour
Contractor crews have built a new SR 16 HOV overpass spanning South Tacoma Way that will connect to I-5 HOV lanes. Work to finish this overpass requires closing South Tacoma Way between S. Pine Street and S. Wilkeson Street during overnight hours. 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
