Sherman Hill Baffling Question

How does one get to Union Pacific’s location called “Sherman” between Laramie and Cheyenne, Wyoming?

(A map service several years ago gave erroneous instructions, thus prompting this topic.)

I wanted to know that when I went to Cheyanne too.

The map in the Dec.1986 Trains shows it 3 miles east of Dale where highway 234 crosses the tracks.Do you carry a lot of gear?
That issue has a 8 page article by MWH called Winter on Sherman Hill.

Exactly how to get there is an answer that changes year to year. Buy yourself a DeLorme Wyoming Atlas and talk to local ranchers once your up there.
Basiclly take I-80 up to the exit of your choice and find your way across to the tunnels or whatever location you want to go to.
