Interstate 25 marker

Interstate business routes are roads connecting a central or commercial district of a city or town with an Interstate bypass. These roads typically follow along local streets often along a former U.S. route or state highway that had been replaced by an Interstate. Interstate business route reassurance markers are signed as either loops or spurs using a green shield shaped and numbered like the shield of the parent Interstate highway.

Along Interstate 25 (I-25), business routes are found in all three states through which I-25 passes: New Mexico, Colorado, and Wyoming. Some states regard Interstate business routes as fully integrated within their state highway system while other states consider them to be either local roads to be maintained by county or municipal authorities or a hybrid of state and local control. Every state along I-25 regards its business routes as fully incorporated members of their respective state maintained highway systems.

Although the public may differentiate between different business routes by the number of the parent route and the location of the route, there is no uniform naming convention. Each state highway department internally uses its own designations to identify segments within its jurisdiction.

All of the business loops within New Mexico are maintained by the New Mexico Department of Transportation (NMDOT). In New Mexico, Interstate business routes are named independently of their parent Interstate's designation with business loops of Interstate 25 (I-25) numbered between 10–19, those of I-10 between 20–29, and those of I-40 between 30–39. New Mexico business loop numbers ascend eastward and northward with gaps in numbering to allow for future designations. I-25 begins with a business route through Williamsburg and Truth or Consequences before proceeding northward with additional routes serving the towns of Socorro, Belen, Las Vegas, Springer, and Raton. These routes largely conform to the current or former alignment of the unsigned U.S. Route 85 (US 85) through these communities before the construction of I-25. NMDOT has decommissioned US 85 throughout the state and no longer signs the highway along its length as US 85 entirely follows I-25 with the single exception of the business loop in Las Vegas. The American Association of State Highway and Transportation Officials (AASHTO), however, continues to recognize the New Mexico portion of US 85 maintaining continuity with sections in adjacent states.
