Highway 116 south of Sebastopol opened early Wednesday after being closed for about 10 hours following a crash into a power pole by a suspected drunken driver.

The roadway, a major route connecting the west county with Highway 101 in Cotati, was opened just after 6:30 a.m., according to the CHP.

The closure occurred after a Mazda Miata smashed the pole at about 8:45 p.m. near Lone Pine Road, said the CHP.

Driver Brenda Jane Kyne, 52, of Cotati was headed east when her car drove onto the shoulder and hit the pole, according to the CHP.

The impact sheared the pole off and live power lines dropped to the ground, according to PG&E.

Firefighters and CHP closed the highway, turning drivers around or directing them to somewhat lengthy detours.

A PG&E repair crew arrived after midnight, according to CHP dispatch logs.

Kyne, who had minor injuries, was arrested on suspicion of drunken driving and booked into the Sonoma County Jail, the CHP said.

This was the second time this week Highway 116 was closed for an extended period of time due to fallen power poles and lines.

Early Monday a large tree fell onto lines in the Guerneville area, pulling down five poles and more power lines.

The highway was closed just west of Guerneville and was shut down all of Monday for the lengthy repairs.
