A new stage of construction on the I-5/SR 16 Realignment and Connections HOV project this spring will bring temporary ramp closures and traffic switches for Tacoma commuters.
As early as April 6, Washington State Department of Transportation contractor Skanska will close the South Sprague Avenue ramp to southbound Interstate 5 through the end of May. Crews will also close the eastbound ramp to South 38thStreet for approximately one week. The closures allow crews to rebuild the southbound collector/distributor lane that runs between eastbound State Route 16 and southbound I-5, and the South 38thStreet ramps.
South Sprague Avenue ramp closure and SR 16 HOV lane shift
In order to rebuild the connecting ramps between eastbound SR 16 and southbound I-5, crews will shift eastbound SR 16 drivers headed to southbound I-5 onto newly-built SR 16 HOV lanes. The work also requires closing the South Sprague Avenue on-ramp to southbound I-5. During the approximate two-month closure, South Sprague Avenue drivers will use the following detour:
- South Sprague Avenue to southbound I-5 drivers will detour to westbound SR 16, exit at South Union Avenue and merge on to eastbound SR 16, where drivers will merge into the left lanes and continue to southbound I-5.
This ramp closure, detour and the traffic shift for eastbound SR 16 travelers will remain in place until work on the eastbound SR 16 to southbound I-5 collector/distributor lanes is complete.
Southbound I-5/South 38thStreet east interchange
For seven days, crews will close the eastbound South 38th Street ramp to traffic so it can be modified for a future phase of construction. Currently this ramp allows drivers from southbound I-5 and State Route 16 to exit to eastbound South 38th Street towards Tacoma’s South End and Eastside neighborhoods.
During the closure, travelers intending to exit at eastbound South 38thStreet will be detoured as follows:
- Eastbound SR 16 drivers will follow southbound I-5 and exit to South 56th Street, merge onto northbound I-5 and use exit #132 to South 38th Street.
- Southbound I-5 drivers will exit to South 56thStreet, merge back onto northbound I-5 and take exit #132 to South 38th
Southbound I-5 drivers coming from Fife who normally use the eastbound South 38thStreet exit can avoid detouring to South 56thStreet by taking the exit to SR 7 to reach South 38th Street.
During this seven-day closure, the southbound I-5 exit 132A to westbound South 38th Street will remain open, but as an exit only.
Once the eastbound South 38thStreet ramp reopens, southbound I-5 and eastbound SR 16 drivers exiting to South 38thStreet may turn right or left at the top of the ramp. Traffic will be controlled by a temporary traffic signal. This gives drivers full access to South 38th Street while crews rebuild the westbound ramp.
The South 38thStreet on-ramp to southbound I-5 will remain open during construction.
Poor weather conditions could delay the timing of the closures.
