I-25 has an interchange with WYO 211 (Horse Creek Road) before US 85 splits to the northeast. There is no direct access from southbound I-25 to northbound US 85 at the latter interchange; southbound traffic uses the WYO 211 interchange to turn around to access northbound US 85.[1]

History
The first section of I-25 to be built with funds from the Federal-Aid Highway Act of 1956 was a section near Cheyenne, which commenced in 1958.[2] Earlier funds from the state government had been used to begin work on a freeway bypass of Casper in 1953; its first 3-mile (4.8 km) section was opened to traffic on October 1, 1960.[3] The final section of the freeway, spanning 26 miles (42 km) between Casper and Kaycee, was opened on February 2, 1982.[4][5]
