Beginning in January, the speed along a section of U.S. 285 between Roswell and Vaughn will be increased to 75 mph, according to a press release from the New Mexico Department of Transportation.
New signs for the area are being prepared and will be installed on northbound and southbound lanes between mile marker 128 and mile marker 200.
A major consideration in the decision to change the existing speed limit was the 85th Percentile Rule — a nationally accepted guideline that uses speed studies to help determine speed limits.
According to the 85th Percentile Rule, an appropriate speed limit is one that is not exceeded by 85 percent of the drivers along a corridor.
Engineers also identify and consider other factors, including; traffic crash data, traffic volumes, roadside development, roadway configuration and condition, the number of intersections and driveways, and sidewalks.
