Niles Canyon Road to remain closed until at least Feb. 23
Niles Canyon Road between Sunol and Fremont will reopen Friday at the earliest as crews work to shore up a portion of the roadway that collapsed earlier this week.
The road - State Route 84 - has been closed in both directions between Old Canyon Road and Main Street in Sunol after the slip-out of a chunk of roadway into Alameda Creek.
Caltrans crews have been shoring up the roadway ahead of another storm system arriving in the region by Sunday.
