A half mile northeast of the freeway, and 400 ft. above it. I've used the same waypoints every 0.1 miles for the past five years, so I could mark changes at specific locations along the right-of-way. The old pump station at 3303 Pecos Rd. was Waypoint #1. Waypoint #3 became multi-use crossing #1. The road in front of the freeway is 35th Ave., which is the access road to the gated luxury development.
