Northwest Parkway is a 9.05-mile (14.56 km) limited-access toll road that runs from US 36 to the I-25/E-470 interchange. Both terminus are in Broomfield, northwest of Denver. In combination with E-470 (47 miles (76 km)) and State Highway 470 (SH 470; 27 miles (43 km)), Northwest Parkway forms a partial beltway of approximately 83 miles (134 km) around the Denver metropolitan area. Some 18 miles (29 km) lie between the west end of Northwest Parkway and the northwest end of SH 470, the opposite end of the beltway.
Northwest Parkway was funded entirely with private money and charges a $5.20 toll. Tolls may be paid using highway-speed electronic tolling.
