U.S. Route 85B (Williams County, North Dakota)

U.S. Route 85B is an approximately temporary auxiliary route of US 85 located entirely within Williams County in the state of North Dakota. The highway serves as an eastern bypass around the city of Williston. The establishment of the route was a temporary solution to the rapid increase in truck traffic in the area due to the North Dakota oil boom. The county plans on eventually replacing the highway with an expressway bypass, dubbed the "Northeastern Truck Reliever Route", once funding is gathered. US 85 already bypasses the city as an expressway to the west.

Route description

Starting at a T intersection with North Dakota Highway 1804 within Williston's city limits, United States Route 85B travels north for just under half a mile mile before curving east for about a third of a mile and turning north. It runs about three miles to intersect with 54th Street Northwest that marks the eastern terminus of County Road 7B. After this it continues north for three more miles. Here, County Road 6 joins it and they run concurrently west for two miles to US Route 85B's terminus at its intersection with United States Route 2 in Williston's city limits. The highway runs roughly parallel to the Little Muddy River for most of its length.
