WSDOT has announced another round of expansion-joint work on and along I-5, similar to what was done earlier this year on parts of the Spokane Street interchange:

South of Interstate 90
There will be five weekend-long closures of the northbound and southbound I-5 Corson Avenue South off-ramps, followed by four weekend closures of the northbound off-ramp to West Seattle and South Spokane Street.

North of Mercer Street
Bridge joint replacement will require two weekends of multiple-lane closures on mainline northbound I-5 just north of Mercer Street starting in late August.

The work starts this weekend, closing the northbound and southbound off-ramps to Corson from noon Friday to 5 am Monday. According to this project page, the dates for closing the ramp to the West Seattle Bridge have not yet been set; we’ll track this project and let you know when they are.
