Road and Bridge

La Plata County's Road & Bridge Division is responsible for maintenance and construction on 653 miles of county-owned roads serving nearly 56,000 county residents. Of these roads, 222 miles are paved, and 431 miles are gravel. Across the Road & Bridge Division's four districts - Marvel, Durango, Ignacio & Bayfield - county crews ensure that this vital infrastructure system serves residents and visitors year-round.

In addition to construction and paving projects, the Road & Bridge Division performs continual maintenance and projects for safety and accessibility. This work includes:
  • Snow plowing
  • Grading
  • Dust suppression
  • Roadside mowing
  • Street sweeping
  • Gravel application
  • Striping

Grading and applying Mag Chloride to County Roads:

Please be aware that grading can change daily depending on weather, priorities, flooding, fire, water, equipment & personnel availability.  This schedule is tentative and is updated weekly.  Under normal conditions grading usually takes 1 day per 2 miles of gravel road. We are now attempting to grade roads for the second time this season and will be done in order of highest priority. Please be patient as we have about 431 miles of gravel roads to grade.  When graded please drive slowly to extend the life of the grade work.  Thank you!

Public meeting slated for Grandview highway improvements
The Colorado Department of Transportation, in partnership with La Plata County and the City of Durango, will hold a public meeting on a draft State Highway Access Control Plan (ACP) for future improvements to Highways 160 and 172. The ACP is a planning document that will inform and drive future access and circulation to the affected routes as development continues in the Grandview area.

An "Access Control Plan" is a long-range transportation plan which designates access locations and their level of access (or movements allowed) for the purpose of bringing those portions of roadway included in the ACP into conformance with their functional classification to the extent feasible. [§ 43-2-147(8)(a), C.R.S.]  An ACP provides an opportunity for local agencies to participate in creating a plan specific to the conditions along a specific highway corridor.

Once completed, the ACP will be adopted by CDOT, La Plata County and the City of Durango through an Intergovernmental Agreement (IGA), which will be followed until the agencies go through a formal amendment process to update the plan.

Implementation of ACP's along a corridor provide the following outcomes:

  • Provide safe, effective, and efficient through travel for traffic.
  • Provide safe, effective, and efficient access to and from Highway 160 and Highway 172 for businesses, residents, and visitors.
  • Maintain compatibility with existing and proposed off-system connections that provide local circulation to support the transportation system.
  • Support the development of alternative modes, including transit, pedestrian, and bicycle routes.
  • Allow for incremental implementation as changes within the corridor occur.
  • Support the economic viability of the plan area.
  • Support local planning efforts.
  • Provide predictability and expectations for access as it relates to land use planning throughout the corridor.

The meeting will be held from 5 to 7 p.m. Thursday, Oct. 19 at the Faith Community Church, 1400 Hwy. 172. Representatives from the involved agencies will provide information and answer questions on the purpose and need of the ACP as well as present the long-term goals of the project. The public is welcome to provide feedback on the ACP.
