SAN DIEGO (NEWS 8) - Major road repairs are underway on South Twin Oaks Valley Road between Craven road and Barham in San Marcos after a sinkhole formed in the middle of the road.
Crews say a water main break is to blame for the sinkhole. Repair workers have been on scene all night and expect to be there at least until mid-Friday morning.
One lane is open each way on Twin Oaks Valley road and authorities say the break is not affecting water supply for nearby residents and businesses.
