Updated to include details about the sewer replacement work at Montgomery Drive and Farmers Lane in Santa Rosa. 

Life slows down in Sonoma County after the weekend excitement of the bicycle race and Rose Parade in Santa Rosa, and American Graffiti cruise in Petaluma. Similarly, road projects continue with little change, a lull before the June 3 start of another Highway 101 improvement project north of Santa Rosa.

Santa Rosa police identify their targeted intersection of the week, and Rob Silva, Sonoma County’s road department operations manager, tells us where paving, tree trimming and roadside brush removal crews will cause traffic delays.

Santa Rosa

This week, Santa Rosa police are monitoring one of the city’s most collision-prone intersections, Cleveland at College avenues, which  last year was tied for sixth place with 7 collisions. As part of a weekly Monday through Friday special enforcement program, Officer Jeff Adams says officers particularly will be looking for drivers not wearing seat belts, who are illegally using cellphones, are speeding, running red lights or committing lane violations.

Each week, the officers pick one of the city’s top 25 collision-troubled intersections to monitor. To read about the city’s other top intersections for collisions, CLICK HERE.

Work also continues on the city’s Petaluma Boulevard South “Road Diet,”  which will reduce the number of lanes from four to two and add a middle turn lane between East Washington Street and D Street. City sources predict the project will take another four weeks to complete, and warn drivers to expect occasional lane closures.


SMART will close the railroad crossing at Adobe Road for 12 hours beginning at 6 a.m. Saturday, June 1, to smooth out the conforms at the rail crossing.
