Highway 12 commuters will encounter single-lane closures in both direction and a closed median at Schouweiler Road near Elma from 7 a.m. through the afternoon hours Friday.

The temporary restrictions will allow Washington State Department of Transportation crews to take advantage of expected favorable weather as they add new deceleration and acceleration lanes and other related improvements.

Drivers on on Schouweiler Road will not be able to turn left to and from US 12, but instead will be limited to making right turns only at the intersection.
