Designated Snow Routes

When a snow or ice event hits Columbia, snow plows must treat and plow the equivalent lane miles of the distance from Columbia to Miami. The Public Works Department, Boone County and the Missouri Department of Transportation share responsibility for treating and plowing streets in and around Columbia. Columbia has more than 1,300 lane miles of streets and more than 1,100 cul-de-sacs. The sheer volume of cul-de-sacs and lane miles makes it necessary to prioritize roads during ice and snow events.                                     

Over one-third of Columbia’s roads, almost 500 lane miles, are priority routes that create a network of major roads and residential streets that extend throughout the City towards as many neighborhoods as possible. They include such residential streets as Battle Avenue, Worley Street, Thornbrook Terrace and more. Their primary purpose is to ensure safe passageways to and from major highways, hospitals, schools, fire stations and commercial areas.

 Street or Area Description Examples
First Priority Streets Major residential and arterial streets for public safety needs e.g., Broadway, Green Meadows Road, Vandiver Drive
Second Priority Streets Heavily traveled collector and residential streets for
Public Safety and City/school bus routes
as well as streets connecting to schools,
hospitals and other critical areas
e.g., Derby Ridge Drive, Fairview, Parkade
Optimization Routes
(Third Priority – Pilot Phase )
This year some new optimization routes are being piloted to facilitate vehicle access to first/second priority routes as well as residential neighborhoods.  e.g., Steeple Chase, Dunbar, Keystone
