[2] On the north side of the highway is the now abandoned track bed of the former El Paso and Southwestern Railroad.

This older section of US 80 used to lead to a railroad overpass, when the EP&SW was still operational.

After the line was abandoned, US 80, now NM 80, was rerouted to a gentle curve bisecting the old track bed.

[4] Continuing north, NM 80 passes Rodeo Airport, then curves northeast, skirting the base of both Granite Peak and Blue Mountain.

[4] NM 80 then makes a straight shot north through a desolate flat desert landscape until it reaches Roadforks.

[2] NM 80 continues for a few hundred feet north, before ending in a trumpet interchange at I-10 Exit 5.

[1][2] While NM 80 ends here, US 80 would have continued east along much of the current route of I-10 to the Texas border.

[8] In 1917 the Dixie Overland Highway auto trail was designated between San Diego, California and Savannah, Georgia over part of NM 4.

US 180 ran from Florence Junction, Arizona to the new U.S. Route 85 northeast of Silver City via Lordsburg.
