Bicycle and Pedestrian Plan

The Bicycle and Pedestrian Plan serves to guide the county in developing a network of on-street bicycle facilities, off-street paths, sidewalks and trails adjacent to roadways. Using a regional approach, the bicycle and pedestrian facilities will be continuous and consistent in the cities, towns and unincorporated county areas. This plan shows a long-term vision for Jefferson County and represents significant future investments that will be constructed over time. No specific funding is currently available to implement the plan.  Projects will be evaluated and constructed as individual roadway corridors are developed. In some cases, bicycle and pedestrian improvements may be considered and implemented with major maintenance work such as pavement overlays.

Major Thoroughfare Plan

The Jefferson County Major Thoroughfare Plan is part of the Comprehensive Master Plan and supports the various community plans.  It identifies the roadway transportation facilities that are currently built or are proposed to be built which are needed to support existing and future land uses.  The County uses the Major Thoroughfare Plan as a guide for long-range capital improvement program planning as well as for evaluating road improvements and right-of-way needs for development proposals. It includes road classifications, design volumes, number of lanes, and minimum design speed for major roadways in the County.

Countywide Transportation Plan (CWTP)

The Countywide Transportation Plan (CWTP) was initiated in 1995 to develop a more coordinated approach to transportation issues in the county. The plan was a cooperative effort between Jefferson County, and the cities of Arvada, Broomfield, Golden, Lakewood, Westminster, and Wheat Ridge. The CWTP consists of a multi-modal plan identifying transit, paratransit, bicycle, pedestrian, transportation control measures, and roadway needs. The Countywide Transportation Plan 2002 Addendum was created to incorporate improvement recommendations from recent planning studies, and to extend the plan to a 2025 horizon year.

The Northwest Quadrant Transportation Feasibility Study

The Northwest Quadrant Transportation Feasibility Study was commissioned by Jefferson County and the cities of Arvada, Golden, Lakewood, Westminster, and Wheat Ridge, with the goal to increase mobility, improve safety, and provide a higher level of service for transportation facilities in Northern Jefferson County over the next 20 years. The study includes recommendations, decisions, and supporting documentation. 

The Northwest Quadrant Transportation Feasibility Study (PDF) 

In 2003, the Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), initiated a National Environmental Policy Act (NEPA) process to study the need, merits, and possible impacts of potential transportation improvements in the Northwest Corridor of the Denver metropolitan area. The Notice of Intent to prepare an Environmental Impact Statement (EIS) appeared in the Federal Register dated July 21, 2003, and identified the proposed action as: “an improved connection between the western terminus of the Northwest Parkway in Broomfield County and the SH 58, I-70, or C-470 freeway systems to the south in Jefferson County.”

In 2007 and 2008, nearing completion of the Draft EIS, CDOT recognized that while transportation improvements in the northwest Denver metropolitan area are needed, federal and state funds are not available to meet these needs in the foreseeable future. The Northwest Corridor NEPA process was therefore discontinued and the Notice of Intent was rescinded. NEPA language and related commitments were removed from the document, to a practical extent, resulting in a Northwest Corridor Transportation and Environmental Planning Study which can serve as a foundation for future projects by CDOT or other entities.

The Study presents information related to the potential benefits and impacts of a No Action Alternative and four build alternatives: Freeway Alternative, Tollway Alternative, Regional Arterial Alternative, and Combined Alternative. The Combined Alternative has been identified as the recommended alternative. 

The Jefferson County Parkway Public Highway Authority was established in 2008 with the mission of completing the last un-built portion of the Denver metropolitan beltway, the Jefferson Parkway, through a public-private partnership to finance, design, build, operate, and maintain the Parkway.  More information on the Authority can be found at www.jppha.org.

2005 Countywide Safety Improvement Program (CSIP)

The 2005 Countywide Safety Improvement Program (CSIP) provides a documentation of high crash locations within unincorporated Jefferson County from 2001 to 2003. High crash locations identified in the CSIP report were analyzed, and safety and/or operational recommendations were made based on field investigation and standards published in the Manual on Uniform Traffic Control Devices (MUTCD).

2002 Countywide Safety Improvement Program (CSIP)

The 2002 Countywide Safety Improvement Program (CSIP) includes documentation of the review of high crash locations within Jefferson County. Information used to determine high crash locations were identified in the 1998, 1999, and 2000 Crash Frequency Locations Studies.
