The Jefferson Parkway is a privately-funded, publicly-owned regional toll road that has been planned for decades and will begin construction in 2020, improving regional connectivity and providing choice and convenience to residents, commuters and travelers in greater metro Denver and northern Colorado.


A project more than five decades in the making

Dating back to the late 1960s, Congress authorized the first studies for a highway system to encircle metro Denver, providing improved regional and long-haul connections between I-25 and I-70.

In 2008, CDOT released the Transportation and Environmental Planning Study (TEPS) with 73 different alternatives evaluated to connect the Northwest Parkway in Broomfield to the C-470 terminus in Golden. The study’s preferred alternative, a combination of projects including approximately 10 miles of new construction (Jefferson Parkway and improvements to existing roads (US 6, SH 93 and Interlocken) balances connectivity with community sensitivities.

The alignment of the Jefferson Parkway has been set for more than a decade. Residential communities and retail developments like Leyden Rock, Candelas and the Candelas Marketplace have all been built around the Jefferson Parkway alignment. The Jefferson Parkway Public Highway Authority has always had signage posted along the alignment notifying the public of the forthcoming highway.

After years of evaluation and debate, Jefferson County, Arvada and Broomfield share a collective vision and have the momentum to get the Jefferson Parkway built. This represents a promise kept.
