Night Lane Closure, One-Way Traffic Control for Eastbound State Route 37 (SR-37) Paving Project in Sonoma County
Work scheduled to start Monday, Oct. 27 from 9 p.m. to 5 a.m. each night
SOLANO COUNTY – Caltrans has scheduled paving work that will require a lane reduction and one-way traffic control on Eastbound State Route 37 (SR-37) just west of the Sonoma Creek Bridge.
One-way traffic control, with a pilot vehicle, will be using the eastbound lane of travel to lead traffic. Work is scheduled to begin the night of Monday, Oct. 27. Working hours are between 9 p.m. and 5 a.m. the next mornings.
There is tentative work scheduled the week of Monday, Nov. 3 during the same hours.
Work is expected to last about five days. All construction is limited to overnight hours in the area.
Construction includes grinding and paving the existing area near between Nobel Road and Skaggs Island Road. No on- or off-ramps on SR-37 are expected to be closed during construction.
A separate paving project on Westbound SR-37 began on Wednesday, Oct. 15 and will continue into the week of Monday, Oct. 20. Hours also are 9 p.m. to 5 a.m. the next mornings for that work.
Please drive with caution. Slow for the Cone Zone and Be Work Zone Alert. Caltrans thanks motorists for their patience while we work to maintain our state’s highways, bridges, and tunnels.
