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.
The tunnel maintenance program tracks CDOT progress in maintaining tunnels on the State Highway System. A letter grade is given every year on maintenance activities at the Eisenhower-Johnson and Hanging Lake tunnels on I-70. Maintenance on these aging tunnels includes tunnel washing and sweeping, ventilation maintenance, snow removal, emergency response and round-the-clock television surveillance.
A letter grade is used to rate traffic services. This maintenance program ensures that stripes on traffic lanes are clearly marked, highway signs are visible, traffic signals are functioning properly and guardrails are intact and functioning.
All public road locations that are not in local roads, from the Colorado Department of Transportation (CDOT). The location of all major roads, does not contain local roads or highways. Contains data on size of road, type, length, etc.
Description This dataset is an attempt to best represent the boundaries of maintenance responsibilities of each region. It is a combination of our Engineering Region boundaries and Maintenance Section boundaries.
