Just before Exit 323, Interstate 80 West reaches Sherman Summit at an elevation of 8,640 feet. This is the highest point on Interstate 80 in the country. Over the distance of about 35 miles, I-80 West went from about 6,000 feet in elevation in Cheyenne to 8,640 feet here at the summit of Sherman Pass. It was a slow, steady climb of over 2,600 feet. (Photo taken 8/15/20).

While the climb to the summit of Sherman Pass on Interstate 80 West was very gradual, the descent into Laramie is quite shorter and steeper. This warning sign alerts trucks of a 5% downgrade ahead which will last for the next 5 miles. This descent of Sherman Pass is certainly no joke, especially in the winter months.
