Northwest Parkway

The Northwest Parkway is a 75-mph toll road that is a part of the Colorado highway system, connecting E-470 at I-25 in the north metro Denver area with U.S. 36 in Broomfield, Colorado. The Parkway is 8.9 miles long, with 4 lanes, 3 major interchanges, 4 ramp plazas and 4 mainline toll plazas.

The project was developed by the Northwest Parkway Public Highway Authority and opened in 2003. In August 2007, it was leased to a private consortium for operations and maintenance under a 99-year concession.
