A long-awaited, $48 million project to replace the I-5 overpass in Lacey at Marvin Road began in October. The diverging diamond interchange is expected to improve traffic flow and reduce collisions.

The overpass over Interstate 5 at Marvin Road will be closed this weekend as crews continue work to install the state’s first diverging diamond interchange.

The overpass will be closed from 10 p.m. Friday, May 31, until 5 a.m. Monday, June 3, to all vehicles, pedestrians and bicyclists.

The northbound exit to Marvin Road also will be closed, but the exit to Quinault Drive will remain open.

Drivers will be detoured via Martin Way (Exit 109) or Nisqually (Exit 114 on I-5).

However, work set to happen during the closure is weather dependent and could be rescheduled. So far, the weekend weather is expected to be partly to mostly sunny with highs in the 70s.

Following the weekend closure, crews will remove a temporary detour to Hogum Bay Road and reopen all lanes on the overpass.

The project is on schedule to be completed in 2020, according to the state Department of Transportation.
