As we prepare for winter weather this weekend, crews are filling trucks to treat roads.
About 5,000 tons of salt is stored on site. Public works crews mix it with sand to treat roads as they become slushy or icy in Chattanooga. The city has 18 trucks prepared.
"It basically just adds a little bit of traction mixed with sand and the salt helps dissolve the frozen portion," Chattanooga Public Works Deputy Director of City Services Rusty Blevins said.
The city will start with primary routes, streets that provide access to fire stations, hospitals, police stations, and schools. Secondary routes or residential areas are next.
The Tennessee Department of Transportation has already started brining the major interstates and state routes.
"Specifically target areas that are vulnerable to freezing like hills, curves, ramps, bridges, interchanges, things of that nature," Tennessee Department of Transportation Community Relations Officer Rae Anne Bradley said.
When the winter weather is over, the public works crews may have more work to do.
"When the moisture gets in an already cracked surface, it expands and contracts like ice in your freezer," Blevins said.
He said it could pop the asphalt portions out, causing potholes, and adding to the list of things that need to be fixed.
Officials encourage the community to stay off the roads this weekend, but if you must travel somewhere, be cautious.
"Be careful, don't get in a hurry, and please give our staff room to do their jobs when they do have to treat the roads," Blevins said.
