This rest stop (called Wyoming’s Summit Visitor Center) is located off of the Lincoln Highway aka route-30, aka Interstate-80,
and has a very large big bust of President Lincoln’s head, and a small museum devoted to the local attractions, historical and natural

And then there’s the information desk where the staff member will help you plan your stay, or provide you with maps and/or pamphlets
and is definitely worth stopping at when driving cross-country.
The Lincoln Highway (which begins in New York City’s Times Square, and ends at San Francisco’s Hyde Street Pier) was the first transcontinental (although some of it was laid brick rather than paved concrete) roadway built for automobile use in America. This was back when our highways were given names instead of numbers, and tended to be a series of interlinking two lane roads that sometimes looped (see map) rather than the four lane unimpeded expressways (cross roads either go over or under) built during the Eisenhower Administration as part of our defence system (intended for quick evacuations of cities and troop movements in case of nuclear war).
Since then the Lincoln was superseded by first Route-30 (two lane roads with intersections), and then Interstate-80. In this part of the country, all three are ONE road.
But the main attraction is the Lincoln monument
