HWY 37 closure causes big delays

Caltrans is reminding motorists that state Highway 37 in Solano and Sonoma counties is closed this weekend for scheduled roadwork.

Vehicles will not be able to access Highway 37 due to major maintenance and paving projects on Highway 37 between state Highway 29 in Solano County and state Highway 121 in Sonoma County, Caltrans spokesman Vince Jacala said.

Jacala said there was significant traffic reported in American Canyon this morning as a result of the detour, which cuts through the city.

The full closure began Friday night and is expected to continue until 5 a.m. on Monday, Jacala said.

The highway will close again at 10 p.m. on Friday, Sept. 26 until 5 a.m. on Monday, Sept. 29, according to Caltrans.

Additionally, five weeknight closures will occur from 10 p.m. to 5 a.m. each night between Monday, Sept. 29 and Friday, Oct. 3, Caltrans officials said.

Jacala said motorists should follow detour signs and expect delays.
