Sherman Summit, WY (No. 1)
Sherman Summit or Sherman Hill Summit, elevation 8,640 ft (2,630 m), is a mountain pass about 7.5 miles (12.1 km) north-northwest of the ghost town of Sherman at 41.23635°N 105.43655°W. While not a particularly rugged mountain crossing, it holds special significance as the highest point along the entire length of transcontinental Interstate 80.
Just southwest of present-day Sherman Summit at 41.23308°N 105.44127°W , at an elevation of about 8,820 ft (2,690 m), is the highest point on the original transcontinental Lincoln Highway and its successor, U.S. 30. This location, where the pavement is still in place, is known simply as The Summit. A huge bronze bust of Abraham Lincoln once stood here; it has been moved to Sherman Summit.
