Weekend work to close downtown ramps and reduce lanes near I-90

SEATTLE – Work to replace two dozen worn and aging bridge expansion joints ramps up again this weekend.

Beginning at 10 p.m., Friday, March 15, contractor crews working for the Washington State Department of Transportation will close all but a single lane of the southbound Interstate 5 collector-distributor, which runs parallel to the mainline between the Washington State Convention Center and I-90.

The on-ramps from Spring and James streets along with the South Dearborn Street off-ramp will also be closed during that time while crews complete the replacement of 10 bridge expansion joints that began Feb. 21 – 24.

All lanes and ramps will reopen to traffic by 5 a.m. on Monday, March 17, in time for the morning commute.

“It’s a balancing act to keep traffic moving while crews are working to replace these bridge joints that are at risk for failure, but when drivers plan ahead and use alternate routes or carpool it really tips the scales in everyone’s favor,” said WSDOT project engineer Aleta Borschowa.

Closure details:

10 p.m. Friday, March 14 until 5 a.m. Monday, March 17

  • The southbound I-5 collector-distributor will be reduced to a single lane between the Washington State Convention Center and I-90. 
  • The on-ramps from Spring and James streets along with the South Dearborn Street off-ramp will be closed.

WSDOT needs help from drivers to keep traffic moving
Drivers who need to travel south through Seattle next weekend should plan ahead for construction and create a commuting strategy:

  • Allow extra time to travel through the work zone.
  • Consider alternate routes such as I-405 or State Route 99.
  • Ride transit, carpool or use other alternate forms of transportation.
  • Travel early in the morning or later in the evening, or reschedule discretionary trips.

Expansion joints help maintain a smooth driving surface by allowing a highway to expand and contract with changing weather. Not only does replacing old expansion joints help preserve I-5 well into the future, it also saves drivers hours of unexpected delays caused by emergency highway repairs.

The is the sixth of nine weekend closures to replace 26 bridge expansion joints on I-5 near the I-90 interchange.

This $2.8 million project will wrap up in spring 2014. For more information, please visit the project website.
