Just east of the state line, the highway bridges Carrizozo Creek, just upstream of where it empties into the Cimarron River.

The remainder of the route is a mostly flat, straight shot into Boise City, with a minor curve to the west of town where it crosses a railroad track.

[2] The road between Kenton and Boise City that is now SH-325 has carried a bevy of designations, and has been intermittently included and excluded from the state highway system over the years.

[4] By 1930, the road was once again state-maintained, and the old SH-11 designation had been done away with as the U.S. route system established itself and superseded the now-redundant state highway numbers that it replaced.

[8] The old US-64 route to Kenton finally received its present-day designation in 1973, when it was numbered after the already-existing NM 325, which once extended to the Oklahoma state line.
