The proposed Jefferson Parkway would run between Highways 93 and 128. It would intersect with but not overlap 93. It would start about five miles north of Golden and head northeast, stopping near to where the Northwest Parkway intersects with U.S. 36.
The Jefferson Parkway Public Highway Authority, established by Jefferson County, Broomfield and Arvada, is trying to secure a private investor to build and manage the highway as a toll road. Since 2011, it has been in discussions with Isolux Corsán, a Spanish-based global corporation focused on infrastructure privatization.
