Drivers can expect at least two months of lengthy backups near the Marvin Road (State Route 510) overpass in Lacey, especially during morning and afternoon commutes. A detour also will affect drivers using the southbound Interstate 5 exit to Marvin Road.
The temporary reduced lanes and detour allow crews to convert the overpass into a more efficient diverging diamond interchange.
The below roadway changes are expected to begin 9:00 p.m. Tuesday, April 9 and be in place around the clock until to mid-June.
I-5 – Southbound I-5 drivers exiting at Marvin Road and turning left onto southbound Marvin Road will instead turn right and detour via Hogum Bay Road Northeast, Willamette Drive Northeast and Marvin Road.
Marvin Road (SR 510) overpass – Marvin Road itself will be reduced to one through lane in each direction at I-5. Northbound Marvin Road drivers will not be able to turn right onto Hogum Bay Road and will be detoured via Willamette Drive Northeast.
WSDOT needs help from drivers
- Check backups from the WSDOT mobile app.
- Allow extra time to account for congestion.
- Travel during non-peak hours whenever possible.
- Take alternate routes and defer discretionary trips.
Additional information about this project is available at I5exit111.com. All users of this overpass are also encouraged to sign up for project updates and check for advance notification of ramp and lane closures.
