From here, the freeway continues north along the western foothills of Las Vegas to pass behind Lone Mountain. Soon afterward, the beltway curves to the east and downgrades from freeway to an expressway (with two at-grade intersections at US 95 south, Oso Blanca Road and Sky Pointe Drive) after it passes the Durango Drive interchange and intersects US 95 at an interchange currently under construction. From there, the beltway continues as a freeway nearly due east along the alignment of Centennial Parkway before entering northern North Las Vegas at Decatur Boulevard. From there it swings northeast, passing by the large Aliante development before turning east again. Much of the final few miles of the route from here on are in undeveloped land, except near the interchange at North 5th Street. The beltway has additional interchanges at Losee Road, North Pecos Road, and North Lamb Boulevard before it swings southeast and reaches its clockwise terminus at I-15, US 93 and Tropical Parkway at an at-grade diamond interchange just west of the Las Vegas Motor Speedway.
