District 4

The New Mexico Department of Transportation - District 4 boundaries encompasses the northeastern part of New Mexico. It is comprised of the following seven counties: Colfax, Guadalupe, Harding, Mora, Quay, San Miguel and Union. The area is exclusively rural with approximately 4% of the total population of the State of New Mexico residing within its boundaries.

District Four has approximately 700 miles of Interstate and US Highways running through it. Commercial vehicle traffic mainly travels through the District on Interstates 25 and 40 plus US Routes 54, 56, 64/87 and 84. The east-west traffic volumes are relatively high along I-40 and US 54. These major truck routes serve as corridors for shipments going to and from East to West through central New Mexico.

The District 4 region is a gateway to travelers. The numerous opportunities for outdoor excursions (boating, camping, fishing, hiking, hunting, skiing, sightseeing and swimming) make District 4 very attractive to both in-state and out-of-state visitors. Numerous State and National Parks are located here plus the abundance of events put on by towns and communities District wide are also contributors to our regions popularity.

The terrain and weather vary considerably in District Four. The elevation ranges from just above 4000 feet in the plains to mountain passes at approximately 9000 feet and mountain peaks at about 11000 feet. The area is bounded by the Front Range of the Rocky Mountains to the west, Mesa and Hill Country in between and the Great Plains to the east and southeast. Weather and road conditions can vary widely within District 4 as the terrain and elevation is very diverse.
