New Mexico State Road 423 is a 17.0 mi (27.4 km) long state highway entirely within Bernalillo County, New Mexico. For its entire length, NM-423 is signed as Paseo del Norte in Albuquerque.
The highway's western terminus is at an intersection with Golf Course Road. The highway then proceeds east intersecting with Interstate 25. The highway's eastern terminus is at an intersection with New Mexico State Road 556.
From Coors Boulevard to Jefferson Boulevard, NM-423 is a freeway with a 60 miles per hour (97 km/h) speed limit. From Jefferson Boulevard to its eastern terminus at NM-556, NM-423 is a 6-lane divided highway with at-grade intersections with speed limits of 45-55 MPH. Proposals to reconstruct its interchange with I-25 would also extend the freeway portion of NM-423 east from Jefferson Boulevard to Louisiana Boulevard.
The New Mexico Department of Transportation (NMDOT) plans a $250 million reconstruction of the I-25/NM-423 interchange, which would replace the existing diamond interchange with a complete interchange. Planning documents indicate that at-grade intersections with Jefferson Boulevard, San Pedro Boulevard, and Louisiana Boulevard will be converted to grade-separated interchanges, thereby extending the NM-423 freeway portion approximately 2 miles (3.2 km) east of where it presently transitions from freeway to limited access surface arterial.[2] Westward extensions to Paseo Del Volcan near Double Eagle II Airport will include limited access designs short of freeway standards, like the current easternmost section .[3]
