From Jacumba, Old Highway 80 heads closer to present-day Interstate 8 near the Desert View tower. Much of the original highway was removed when the Interstate 8 grade into Mountain Springs was built. The highway in Mountain Springs has two tracks, an original as well as a rebuilt segment, which can be easily viewed from Interstate 8. This section is now private property, so photographing this section would be trespassing.
If you exit at the Mountain Springs and Interstate 8 interchange, you can view segments on both sides. Turn right, and you can view the two segements and photograph them up to the private property fence. Turn left and in between the west-bound and east-bound lanes, you can see the highway as it descends to the desert. Interstate 8 surrounds this section on both sides. West-bound traffic follows Devils Canyon, which was not used by Highway 80. East-bound traffic follows Myer Creek Canyon, which Highway 80 used to reach Ocotillo.
Highway 80 ends at a cliff where Interstate 8 was cut in. Most of this section to the Millers Garage area West of Ocotillo is a broken segement. While Interstate 8 takes a large cut through the canyon, Highway 80 followed the canyon contours. Thus, in several sections, you can see old broken segments up and down the canyon as you descend the Interstate.
