GH-10A is one of a number of orphaned suffixed routes on Guam; it bears no physical connection to its parent, GH-10 located elsewhere in Barrigada.

In fact, GH-10A (named Chalan Pasaheru) is considered a very important route in its own right, as its primary purpose is to provide access to Antonio B.

Although unnumbered, there is a key junction along the route into the Tiyan area that was once Naval Air Station Guam.

The intersection provides a further link into Barrigada as well as access to other airport and industrial facilities.

The eastern terminus at GH-16 is unique by Guam standards in that it is a grade-separated single-point urban interchange rather than an intersection.
