Route description

WYO 257 connects WYO 220 with the west end of the Shoshoni Bypass (US 20/US 26) in Casper. WYO 257 provides a direct connection from WYO 220 to Interstate 25 (I-25) around the west side of Casper for approximately 7.3 miles (11.7 km).[1]

History

Need for a new roadway around the west side of Casper had been discussed for many years and has been included in various local planning documents for years.[2] WYO 257 serves as a truck bypass route around the west side of Casper and alleviates traffic along the current signed truck route on CY Avenue to Wyoming Boulevard to US 20 Business/US 26 Business. WYO 257 was opened to the public on December 31, 2015.

Major intersections

The entire route is in Natrona County.
