Despite the I-90 bridge remaining open during the Seafair Weekend Festival, travelers may still have some traffic headaches with Revive I-5 work resuming in Seattle this weekend.

The Washington State Department of Transportation (WSDOT) said it is only about halfway through its weekend lane closures for Revive I-5 and that the work must continue.

WSDOT is focusing on expansion joints on the right side south of the collector/distributor near the I-90 interchange.

The three right lanes of southbound I-5 will be closed where the collector/distributor rejoins the interstate from 7:30 p.m. Friday through 5 a.m. Monday.

Drivers entering the collector/distributor will have to exit to I-90, Dearborn Street, Fourth Avenue South or Airport Way. The ramp from the collector/distributor to southbound I-5 will be closed. 

Those using the southbound I-5 James Street on-ramp will need to use a collector/distributor exit. The Spring Street on-ramp and the South Forest Street off-ramp also will be closed.

WSDOT is asking drivers to plan ahead this weekend and take alternate routes, including I-405.

WSDOT said eastbound and westbound I-90 off-ramps to southbound I-5 will remain open all weekend to help keep traffic flowing.
