DDOT hasn't sent out a reminder, but I'll post it anyway: the M Street/Washington Navy Yard exit off of I-295 North, along with portions of M and 12th streets,
are supposed to be closed this weekend to continue work on the demolition of the ramps to RFK. The closure times are listed as being from
6:30 pm on July 24 through 6:30 am July 27; access to the boathouses and ramps along Water Street will be open, and the 8th Street SE exit off of I-295 North can still be used.
They've posted three maps showing the detours that will be in effect.
