RUTHER GLEN, Va. (AP) — Hundreds of motorists were stranded all night in snow and freezing temperatures along a 50-mile stretch of Interstate 95 after a crash involving six tractor-trailers in Virginia, where authorities were struggling Tuesday to reach them.

Both directions of traffic on I-95 came to a standstill Monday between Ruther Glen, Virginia, in Caroline County and exit 152 in Dumfries, Prince William County, the Virginia Department of Transportation said. “Crews will start taking people off at any available interchange to get them,” the agency tweeted at 5:20 a.m. Tuesday.

Gov. Ralph Northam tweeted that his team responded through the night alongside state police, transportation and emergency management officials. “An emergency message is going to all stranded drivers connecting them to support, and the state is working with localities to open warming shelters as needed. While sunlight is expected to help @VaDOT clear the road, all Virginians should continue to avoid 1-95,” he added.

Crews were working to remove stopped trucks, plow snow, de-ice the roadway and guide stranded motorists to the nearest exits along the U.S. East Coast’s main north-south highway, the transportation agency said.

“We know many travelers have been stuck on Interstate 95 in our region for extraordinary periods of time over the past 24 hours, in some cases since Monday morning. This is unprecedented, and we continue to steadily move stopped trucks to make progress toward restoring lanes. In addition to clearing the trucks, we are treating for snow and several inches of ice that has accumulated around them to ensure that when the lanes reopen, motorists can safely proceed to their destination,” said Marcie Parker, the agency’s Fredericksburg District engineer.

The tractor-trailer collision Monday afternoon caused no injuries but brought traffic to a standstill, and it became impossible to move as the snow accumulated. Hours passed with hundreds of motorists posting increasingly desperate messages on social media about running out of fuel, food and water.

Between 7 to 11 inches of snow accumulated in the area during Monday’s blizzard, according to the National Weather Service, and thousands of accidents and stranded vehicles were reported throughout central and northern Virginia. As of 3:30 p.m. Monday, Virginia State Police had responded to more than 2,000 calls for service due to treacherous road conditions, The Free Lance-Star in Fredericksburg reported.

Compounding the challenges, traffic cameras went offline as much of central Virginia lost power in the storm, VDOT said. More than 281,000 customers remained without electricity on Tuesday, according to poweroutage.us.

“I’ve never seen anything like it,” Emily Clementson, a truck driver, told NBC Washington. She urged stuck motorists to ask truck drivers if they have food or water to share since many carry extra supplies in case they get stranded.

The agency tweeted to the stranded drivers on Monday that reinforcements were arriving from other states to help get them moving again.

“We wish we had a timetable, ETA, or an educated guess on when travel will resume on I-95. It’s at a standstill in our area with multiple incidents,” the tweet read. “It’s frustrating & scary. Please know our crews don’t stop. Crews will work 24/7 until ALL state-maintained roads are safe for travel.”

State police had warned people to avoid driving unless absolutely necessary, especially as evening and freezing temperatures set in.

“Due to the heavy snowfall concentrated in that area, road conditions rapidly turned treacherous for commercial and passenger vehicles,” state police reported in a press release. “VSP troopers, wreckers, and VDOT crews continue to work as quickly as the weather and roads will safely permit to get stuck vehicles cleared and traffic moving again on I-95.”

The stranded motorists included NBC News correspondent Josh Lederman, who spoke on NBC’s “Today” show on Tuesday via video feed from his car, with a dog in the back seat. He said he’d been stuck about 30 miles (48 kilometers) south of Washington, D.C., since 8 p.m. Monday.

“I don’t have any food or water. I have gas, but how long is that going to last?” Lederman said.

All night, it turned out. At around daybreak, VDOT announced that it was beginning to try to reach the stranded motorists.

“I think the word is dystopian,” Lederman said. “We started to see a lot of drivers turning their cars off to conserve gas, people running out of food and water, kids and pets holed up for so many hours, people letting their pets out of the car to try to walk them on the street. And in the meantime, no signs of any emergency vehicles that we could see. Now, you don’t know if that’s because they can’t get to where you are, but you really start to think if there was a medical emergency, someone that was out of gas and out of heat — you know it’s 26 degrees and there’s no way that anybody can get to you in this situation.”
