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.

County Road 240 (Florida Road) to be closed for bridge deck replacement

County Road 240 (Florida Road) will be closed for a bridge deck replacement from May 31 through June 16. The bridge is in the 8000 block of C.R. 240 approximately ½ mile northeast of C.R. 248. Electronic variable message signs are now in place near the bridge at both approaches. The project will require the complete removal of the existing bridge deck structure, which was constructed in 1982, so a single lane pass-through is not possible and both lanes of traffic will be closed. The detour for this project will be via C.R.s 245, 501 and 502. We understand the inconvenience that this detour will cause for area residents and will work to finish the project as quickly as possible.

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. During the summer months all districts grade by order of road aka. 300, 301, 302 etc.  The order can change depending on 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!
