Section of Marin County highway reduced to single lane for construction of retaining wall

Starting Monday, a 750-foot stretch of Panoramic Highway will be reduced to one lane for construction of a retaining wall. A temporary traffic signal will be in operation to allow alternating two-way access. A Mount Tamalpais State Park trail downhill of the work zone will also be closed during construction work hours.  

People traveling between the Mount Tamalpais area and Stinson Beach areas should expect traffic delays of up to 10 minutes, according to a Marin County press release published on Thursday.
