San Juan County Commission approved a Memorandum of Understanding (MOU) between San Juan County and NDOT in the December 18, 2018 Commission meeting. The MOU allows San Juan County to enter into job-specific Inter-Governmental Agreements (IGA). Under the IGA San Juan County may complete specif projects or maintenance chosen and funded by NDOT.

San Juan County also has a current Cooperative Agreement with the BIA for quarterly (four times per year) blade maintenance of select “dirt” or “natural” surface roads owned by the BIA.

San Juan County has successfully installed a revolutionary product for testing on County Roads. The three roads that have been treated are B2481- Landfill Road, B110 Dude Ranch and B1261- Guest Ranch Spur. The product is incorporated by spreading the dry material on the surface then utilizing a road grinder/reclaimer it is ground into the existing materials to the specified depth and then shaped, compacted and sealed with a double pin chip seal. The completed product is very similar to an asphalt paved road. If the product performs to manufacturer claims, San Juan County will be able to greatly improve roads at a fraction of the cost for conventional full replacement costs of our aging road inventory.

Future Projects:

REDUCED SPEED LIMITS-San Juan Spanish Valley Sewer and Water Project– Many roads in the Spanish Valley area of Northern San Juan County will begin seeing impacts of a project to install new water and sewer systems. As a precaution, the speed limit within the impacted areas have been reduced to 25 MPH for the duration of the project. Reduced speeds will promote safety to the road users as well as the individuals completing the work for these projects. The project will begin early in January 2019 and is anticipated to last approximately 1 year. We thank you for your understanding and patience! For more information on the project click here.
