Drivers should anticipate detours beginning next week as crews close a section of D Street.
The closure is scheduled for 50 days and will allow work crews to begin construction of two roundabouts on Peace Portal Drive and D Street near the I-5 overpass.
Washington state Department of Transportation spokesperson Dustin Terpening said downtown businesses will remain open and detour routes will be clearly marked to help drivers around the construction.
Specifically, crews will close the northbound and southbound I-5 on-ramps as well as D Street between the northbound on-ramp and southbound off-ramps.
The 50-day closure will speed up construction and reduce impacts to drivers and local businesses by allowing crews to build the roundabouts quickly and efficiently.
“We’re ready to get in and out of here as quickly as possible," project engineer Chris Damitio said. “Road construction can be an inconvenience, but we believe we have planned this closure to minimize the disruption to drivers and local businesses.”
Terpening added that DOT has included incentives and penalties in the contract to encourage the contractor to complete the 50-day closure early.
In addition to the roundabouts, WSDOT will make modifications to I-5 to help slow drivers down as they approach the border. This work will be completed after the 50-day closure.

The project is fully funded by the federal government in an effort to complement the General Service Administration improvements at the Peace Arch border crossing.
