D.C. transportation, and Virginia and Maryland highway officials say many roadways are likely to remain treacherous during the Monday morning commute, as black ice is expected with the freezing of moisture left by the blizzard.
D.C. Mayor Adrian Fenty, along with District Department of Transportation (DDOT) Director Gabe Klein and Department of Public Works (DPW) Director, William O. Howland, Jr., said efforts are underway to clean up the roadways in time for Monday's commute, but drivers are reminded to keep their speeds down.
District officials are also asking that drivers stay off the roadways as much as possible so crews can plow the streets.
State Highway Administration spokeswoman Lora Rakowski says interstate highways are down to bare pavement, and crews are making good progress on primary and some secondary roads.
But Rakowski says drivers shouldn't become "complacent'' just because many roads are clear. She says exit ramps could still pose
difficulties, and drivers could have trouble at intersections where some lanes remain blocked or where plows have left snow in spots.
Rakowski says highway officials are expecting "close to normal traffic flow'' on Monday, with both commuters and holiday travelers
taking to their cars.
The State Highway Administration maintains 17,000 lane miles of road.
