Buck said the state will urge motorists to use restrooms at nearby hotels, restaurants and gas stations while the rest area is closed.
"For the purpose of a bathroom, you only have to go five minutes on either side (of Sideling Hill)," Buck said. "Will the amenities be the same? Probably not. But a bathroom is a bathroom."
The state will post signs to let motorists know about establishments with restrooms, Buck said. If everything goes well, business at those places will increase.
"Hopefully, people will eat their food and stay at their hotels," Buck said.
The closure at Sideling Hill will not affect truck drivers because trucks were not permitted on the premises, Buck said.
The nearest public welcome center to Sideling Hill on Interstate 68 is about 75 miles to the west at Friendsville, Md., according to a list of Maryland rest areas. The hours at that welcome center are 8 a.m. to 5 p.m.
Tom Riford, president and CEO of the Hagerstown-Washington County Convention and Visitors Bureau, said in an e-mail that the restroom closing at Sideling Hill would hurt tourism in Washington County because people will drive straight through without stopping.
"Sideling Hill still has travel information," Riford said. "But after the rest area is closed, with no restroom hours, there'll be no chance to tell travelers what's here."
