More Highway 101 closures are on tap this week in Petaluma for continuing construction on the highway.
Caltrans will close as many as two lanes of northbound and southbound Highway 101 at the Old Redwood Highway interchange tonight through Friday.
At least one lane will remain open in each direction at all times during the 10 p.m. to 5 a.m. work.
Also, the northbound off- and on-ramps at Old Redwood Highway will close overnight tonight and Wednesday. During the ramp closures, motorists may detour to the East Washington Street interchange.
Other closures will be announced as the work is scheduled.
