Other CDOT Studies

Studies & Assessments for non-highway issues. For example, railroad relocation and mobility.
AGS Feasibility Study
Advanced Guideway System (AGS) Feasibility Study - This study is a result of the Colorado Department of Transportation's (CDOT’s) and FHWA’s selection of the I-70 Mountain Corridor Preferred Alternative which specifies in order to best meet the purpose and need of a transportation solution on the Mountain Corridor, a multi-modal solution is needed including implementation of an Advanced Guideway System (AGS). Keywords: Studies, Interstates, Non-highways
CDOT Rail Relocation Implementation Study
As the Front Range has grown, there has been much discussion of the need to relocate through-freight train traffic away from the communities along the Front Range. In 2002 BNSF and UP proposed a Front Range Railroad Infrastructure Rationalization Project, which would improve and relocate freight rail infrastructure, moving through-freight traffic east of the Front Range while still maintaining local freight service. Keywords: Studies, Non-Highways
City of Glenwood Springs South Bridge EA
The City of Glenwood Springs, with the Colorado Department of Transportation (CDOT), Federal Highway Administration (FHWA) and Garfield County conducted the Environmental Assessment. The purpose of the South Bridge project is to identify a critical second route between SH 82 and the west side of the Roaring Fork River in the southern portion of Glenwood Springs. This second route responds to the previous Congressional earmark for the Glenwood Springs, South Bridge (new, off-system bridge), Public Law 109-59, 109th Congress. The project will respond to identified transportation needs, such as lack of emergency vehicle access route redundancy and increasing mobility issues along the current primary access route (Midland Avenue) caused by increased growth in the area. Keywords: Studies, Non-Highways
File Eastern Colorado Mobility Study
April 2002 - The Eastern Colorado Mobility Study was undertaken to assist the Transportation Commission of Colorado in making investment decisions regarding infrastructure improvements to enhance freight mobility in a large part of the state. The study area includes all of eastern Colorado, extending to the I-25 corridor on the west and Colorado’s borders on the north, east and south. Keywords: Studies, Non-Highways
Intercity and Regional Bus Network Study
This project will focus on the next steps including refining plans for both intercity and regional networks and building a foundation to support financing and implementation of these services. Keywords: Studies, Non-highways, Intercity and Regional Bus Network Study
Interregional Connectivity Study
The Colorado Department of Transportation (CDOT) Division of Transit & Rail recently kicked off an Interregional Connectivity Study (ICS), which will examine technology, alignment, and financial/funding options for implementing high speed rail along the Front Range. Keywords: Studies, Non-highways, high speed rail
Northwest Corridor EIS
Northwest Corridor Transportation and Environmental Planning Study - July 2008 - 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. This connection is considered necessary to address the need for system linkage, to provide for existing and projected transportation demand, to improve safety, and to enhance modal interrelationships, within the Northwestern Quadrant of the Denver Metropolitan Area.” Keywords: Studies, Non-Highways
State Passenger and Freight Rail Plan
With the help of CDOT’s public and private stakeholders and the cooperation of the Federal Railroad Administration, CDOT will begin the task of developing Colorado’s first statewide passenger and freight rail plan. Keywords: Studies, Non-Highways
