River Road seems to have turned into a river this morning. A huge water main broke, flooding the road with four feet of water and trapping more than a dozen people in their cars. They had to use boats and helicopters to rescue some of them. More info including pictures and video at channel 7. The break seems to be on River Rd between Bradley Blvd and Seven Locks Rd, just outside the beltway.
Parts of Bethesda (including my house) are currently experiencing low water pressure. I'd expect it to get worse before it gets better, prepare for a bit of time without water and the inevitable boil water advisory, keep an eye on the WSSC homepage.
