Our History

  • On July 1999 the Northwest Parkway Public Highway Authority (the “Authority”) was formed with the purpose of building an authority financed highway linking E-470/I-25 to US 36, without resourcing to taxpayer money.
  • The Authority is comprised of two member jurisdictions, the City and County of Broomfield and the City of Lafayette. Ex-officio members are the Jefferson County, City of Arvada, Regional Transportation District (RTD), Interlocken Metropolitan District, and the Colorado Department of Transportation (CDOT).
  • Construction of the Parkway commenced in June 2001, under a design/build contract by the Authority. The Parkway opened to traffic on November 24, 2003, and toll collection commenced on January 1, 2004.
  • On November 21, 2007, the Northwest Parkway LLC (the “Concessionaire”), entered into a 99- year concession and lease agreement for the operation and maintenance of the Parkway from the Authority. To learn more about the Concession Lease click here.
  • On January 1, 2010, the Parkway converted to an All-Electronic Toll Road, meaning you no longer have to stop to pay your tolls when you travel, thus increasing convenience and safety.
  • On March 9, 2017, a Consortium formed by three infra-structure funds completed the acquisition of 100% of the Concessionaire Northwest Parkway LLC and its Operating Company Go-Pass Mobility Services LLC from former shareholder Brisa.
  • On April 18, 2024, Vinci Highways completed the acquisition of 100% of the Concessionaire Northwest Parkway LLC and its Operating Company Go-Pass Mobility Services LLC from the former infra-structure consortium shareholder. More info about the new shareholders can be found here.
