CDOT’s maintenance program establishes a target letter grade it expects to achieve for snow and ice control each year. During the winter, CDOT maintenance workers complete surveys to grade their performance using established criteria based on the year’s budget. Higher grades are typically achieved during lower-cost, milder winters.

Traffic counts on highways and various calculations, from Colorado Department of Transportation (CDOT), for 2016

Mileposts (or mile markers) along highways and their locations collection during GPS mapping efforts in the early 2000s from the Colorado Department of Transportation (CDOT).

Bridges in good condition typically have a rating from 80 to 100 and generally meet all safety and geometry standards. Good structures typically only require preservation-focused maintenance. Bridges in fair condition have a sufficiency rating from 50 to 80 and are qualified as structurally deficient or functionally obsolete. They marginally satisfy safety and geometry standards and require preservation-focused maintenance or occasional corrective rehabilitation work. Any bridge with a sufficiency rating of less than 50 and a status of structurally deficient or functionally obsolete is considered to be in poor condition. Bridges rated poor have exceeded their viable service life and require replacement or major rehabilitation.

Features in this dataset represent traffic counts on public roads under local jurisdiction that are functionally classified as arterials or collectors. Features are represented by polyline (linear) geographic shapes from the Colorado Department of Transportation (CDOT), for 2014
