Cleaning up after the historic snowstorm that dumped more than two feet of snow on parts of the Mid-Atlantic states will keep a handful of National Park System units closed Tuesday.

National Park Service staff say many Greater Washington Area national parks, facilities, and roads will remain closed Tuesday as crews continue to dig out from the blizzard.

"Employee and public safety is our top priority as we work to reopen parks and roads as soon as possible. Decisions on operating status are still pending for many parks," said NPS spokeswoman Jenny Anzelmo-Sarles.

Crews continue to clear and treat major roadways, sidewalks, and Metro station entrances located on National Park Service lands. Efforts to reopen parks, assess facilities, and clear roads, trails, and sidewalks will continue at least through the week, she wrote in a release. 

Roads and other park areas will continue to be closed on an as-needed basis to allow crews to move snow and to protect visitors. The public is asked to respect barricades and unanticipated road closures, and check with individual parks for specific road updates. Snow and moisture coupled with freeze-thaw cycles can damage roads and sidewalks, the release said, adding that drivers should expect to find potholes in the coming days and weeks. 

Closure Notes:

* Beach Drive is closed in both directions between Broad Branch Road and Joyce Road.

* A decision is still pending on the reversible lane changes on Rock Creek Parkway. Drivers should stay alert and check their local news.

* Crews will not begin clearing the Capital Crescent Trail until Wednesday.

Specific parks that planned to be closed Tuesday include park offices and visitors centers at Chesapeake and Ohio Canal National Historical Park and the Hampton National Historic Site in Maryland. Morristown National Historical Park in New Jersey planned to reopen by mid-day Tuesday.
