 There is a fuel spill. This sounds like it could be worse before it gets better. So if in Montgomery County and Bethesda do not commit to the outer loop past Old Georgetown Road, you could rejoin from River Road plan ahead. Nothing currently slowing the spur. They seem to be getting by, but watch for any direction as you're going underneath a fully engulfed tractor trailer. Also on the beltway in Montgomery County, slippery when wet. A new crash is on the inner loop. It's near Georgia Avenue. Response was just landing to the scene.
