Trail WFR (West Frontage Road) is a doubletrack (though a small section has reduced to singletrack) trail that borders the west side of Road LNR (Libramiento Norte Road) as LNR summits the pass between the Oaxaca de Juarez/San Felipe del Agua valley and the Trinidad de Viguera/Etla valley. At the south and north ends where it ties into Road LNR the tread is a rough dirt road. As it parallels LNR, it climbs steeply on each end so as to reach an elevation about 15 meters higher than LNR. I.e. LNR has a gentler grade as it cross the pass than WFR. The main usefulness of Trail WFR is that is allow access to several trails on the west side of Road LNR near the pass summit (e.g. Trails A, ED, Es, and RR). Trail ZZ (Zig Zag) provides a shortcut between the middle of WFR and LNR below. Handy for crossing from Trail TTT over to the aforementioned trails on the west side of LNR without having to descend on LNR to only re-ascend on WFR.
