As road conditions started deteriorating after noon on Friday, police in Sherman and Denison were called to numerous wrecks and to assist stranded motorists.

Sherman Police Sgt. D.M. Hampton said between midnight and 4 p.m. Friday, police responded to 36 calls of wrecks on city streets with three of those involving minor injuries. Police also responded to four calls of motorist assists, which Hampton said involved vehicles getting stuck from the icy road conditions. Through Saturday afternoon, Sherman officials said the number of wrecks increased to about 55.

“It’s still dangerous and will continue to be dangerous,” Hampton said of road conditions Friday afternoon.

Denison Police Lt. Mike Eppler said between 10 a.m. and 4 p.m. on Friday, police responded to 12 wrecks and motorist assists. Most of these wrecks were fender benders, he said, but one wreck did cause a minor injury. By 10 p.m., Eppler said the number of wrecks increased to 20.

“Some of them had substantial damage, but most of them were minor because there weren’t any injuries,” Eppler said Friday afternoon.

Texas Department of Public Safety Trooper Mark Tackett said at about 4:30 p.m. troopers had responded to only one wreck in Grayson County. A trooper investigated a one-vehicle rollover at about 12:45 p.m. on U.S. Highway 69 south of Savage Road. 

A Ford SUV was traveling southbound on U.S. Highway 69, south of Savage Road and, at about 12:45 p.m., the driver lost control of the vehicle and it veered off the roadway to the east side, first responders on scene said.

The vehicle rolled to its side and came to a stop with its front facing north. The vehicle’s two occupants were not injured in the wreck, Bells medics said. A Texas Department of Public Safety trooper responded and investigated the crash.

Shortly after this crash occurred, another wreck was reported on Highway 69 in Whitewright. Three vehicles collided near Bois D Arc Street, and no one was injured. Whitewright Police investigated the second wreck.

Several wrecks were also reported on U.S. Highway 75 in Sherman, which Hampton said led to wrecks on top of other wrecks. A multiple vehicle wreck occurred on northbound Highway 75 near Lamar Street and resulted in a road closure. The northbound traffic was diverted onto the service road for over an hour.

Sherman Police reported the 1200 block of West Washington Street and the Grand Street overpass were closed due to the icy conditions. Eppler said he wasn’t aware of any Friday road closures in Denison.

The roads continued to be hazardous into Saturday morning as water on the roadways froze after sundown. Eppler advised residents to be particularly cautious in hilly areas and to give plenty of time for travel.

“Try to know where you’re going ahead of time — know a good route to go,” Eppler said. “If you see cars that are backed-up somewhere, try to go a different direction if you can.”

Hampton recommended that residents not go out during the icy conditions, and if they must, to slow down. He said the best way to avoid a wreck is to not get out on the roadway.

While many roads were covered in snow and ice Saturday morning, by the afternoon, much of it had melted away. Shaded roadways had patches of snow and ice that did not melt and were likely to refreeze overnight as the temperature was expected to dip down to 19 degrees.
