UPDATE (March 2, 6:10 a.m.): According to Caltrans, both directions of state Route 78 from Bandy Canyon Road to Haverford Road have been reopened.

RAMONA, Calif. - A stretch of state Route 78 in the Ramona area where boulders fell from rain-soaked hillsides is expected to remain closed through the Wednesday evening commute.

The highway was closed in both directions between Academy and Haverford roads Tuesday "due to the threat of boulders falling from the slope," according to Caltrans.

Currently, crews are working to clear the boulders. Just before 3:30 p.m., crews detonated the boulders to help clear the road. 10News' Jon Horn was at the scene when the explosion went off:

Caltrans San Diego said they hope to get SR-78 at Brady Canyon open by later tonight, now that the boulders were now in smaller pieces, following the blast.

State transportation officials said the only way into Ramona would be via state Route 67. Eastbound motorists on state Route 78 will be detoured off at Bandy Canyon Road, then will take Highland Valley Road to state Route 67.
