Edgar Maddison Welch traveled from North Carolina to Washington, D.C., in 2016 and fired shots in Comet Ping Pong restaurant, acting on a conspiracy theory that had spread online. A homeless man suspected of attempting to start a fire with a “flamethrower” was bundled to the ground and zip-tied by Angelenos as wildfires continued to spread.

TDOT wants to assure motorists that it’s ready to clear roadways of ice and snow. Crews across the Midstate are readied with snowplows and brine trucks.

The best advice from officials this weekend is to travel only if necessary. Crews are focusing on bridges, overpasses and high-elevation areas, which tend to freeze first.

Our main focus will be on high-traffic spots like the I-55 and I-40 bridges, as well as the I-40 flyover,” a TDOT spokesperson said.

NDOT is gearing up for Friday's winter storm, pre-treating roads all across Nashville.
