Ice & Snow Alerts

Nov. 12, 2018:

Overnight temperatures may lead to refreeze potential. So crews will remain focused on first and second priority routes until 7 p.m. when an overnight 8-person crew will report.


Nov. 11, 2018:

Columbia Public Works plans to have an 8-person crew in at 4 a.m. Monday, Nov. 12 focusing on first and second priority routes.

Some precipitation is expected Sunday evening and overnight. At this point it is not known how much precipitation will occur. Temperatures are anticipated to be above freezing until early Monday morning, but will likely fall below freezing at some point. Crews will focus on first and second priorities as wet pavement may refreeze early in the morning. Spotty slick conditions may occur.

Snow 1/2″ to 1″ is expected Monday during the day.

Winter Weather Policies and Procedures

It is our goal that all streets in Columbia are passable by a front-wheel drive vehicle as soon as possible. 

The City of Columbia has more than 1,350 lane miles of streets including 1,100 cul-de-sacs maintained by Public Works. The sheer volume of cul-de-sacs and lane miles makes it necessary to prioritize roads during ice and snow events.         

There are 470 lane miles of designated snow routes, or priority routes, in Columbia. These priority routes create a network of major roads and residential streets extending throughout the city. Their primary purpose is to ensure safe passageway to highways, hospitals, schools, fire stations and commercial areas.  Every event is not exactly the same, but generally speaking a typical response occurs in phases:          

  • Pretreat bridges, curves, hills and intersections as needed;
  • Clear priority routes to “near normal” condition.
  • Make sure all other City streets are “passable” by a front-wheel-drive vehicle to facilitate access to priority routes.
  • Respond to any reports received by the City Contact Center (573.874.2489) that a street or intersection is not “passable” and needs additional attention.               

Priority routes are plowed and treated 24 hours per day as needed during a winter weather event; other routes are plowed and treated to a passable condition during normal business hours. When snow reaches 4 inches, all of the City’s 1,350 lane miles are plowed and treated to a passable condition 24/7 after priority routes are near normal.  

There is no parking allowed on priority routes when snow accumulates 2 inches or more. Parking Utility staff do their best to warn drivers, but vehicles will be ticketed and towed at the owner’s expense if they are not moved. To be reminded of when it’s time to move cars off of priority routes, sign up for alerts at or by texting the phrase COLUMBIAPW to 888777.
