Wyoming Highway 377 (WYO 377) was a short 1.96-mile-long (3.2 km) Wyoming state road in central Sweetwater County that served the community of Point of Rocks and the Jim Bridger Power Plant. It was decommissioned in 2017.

Route description

Wyoming Highway 377 began at exit 130 of Interstate 80/US 30 in Point of Rocks, a Census-designated place located east of Rock Springs. WYO 377 traveled eastward along the north side of Interstate 80/US Route 30, which it paralleled. At just under 2 miles, Highway 377 ended, though the roadway continued north, as 9 Mile Road, providing access to and from the Jim Bridger Power Station.[2][3]


Highway 377 was the former alignment of US 30 (Lincoln Highway) through this area and paralleled Interstate 80 which carries the present day routing of US 30.[3]

Major intersections

The entire route was in Sweetwater County. [4]
