56th Avenue, Quebec St. to Havana St. Environmental Assessment

This Environmental Assessment (EA) identifies and evaluates the impacts of proposed multi-modal transportation improvements on 56th Avenue between Quebec Street and Havana Street in Denver, Colorado. The purpose of the proposed improvements is to meet forecast mobility and accessibility needs for users of all modes (including pedestrians, bicyclists, cars, buses, and trucks) on the existing 56th Avenue alignment.

I-25 Valley Highway Environmental Impact Statement (EIS) and ROD

November 2006 - The Final Environmental Impact Statement (EIS) for the Valley Highway Project details the Preferred Alternative and project phasing for the reconfiguration and redesign of I-25 between Logan and US 6 (6th Avenue) and elements of US 6 from I-25 to Federal Boulevard. The purpose of the Record of Decision (ROD) is to document the FHWA’s decision on the I-25 Valley Highway Project. Keywords: Studies, Interstates

US 287 Loveland to Fort Collins Environmental Overview Study (EOS)

January 2007 - The Colorado Department of Transportation (CDOT) developed and initiated the Environmental Overview Study (EOS) process. The EOS process is structured to provide a basis for long-term roadway improvements and to provide support for local planning decisions while considering environmental resources decisions. While no funds are currently programmed for construction, the intended outcome of the process is the preservation of a corridor for future transportation improvements. Through this process, future improvements to the state highway system can be integrated with other local and regional transportation plans resulting in a proactive, environmentally sensitive transportation vision within the North Front Range.

US 34 Environmental Assessment (EA)

April 2007 - This project encompasses approximately 6 miles of US 34 (also known as Eisenhower Boulevard) in Loveland, Colorado. The project corridor extends between a western terminus at US 287 (North Lincoln Avenue and North Cleveland Avenue one-way pair) and an eastern terminus of Larimer County Road 3 (LCR 3), 1.5 miles east of the I-25 interchange. The purpose of the proposed project is to provide an improved transportation facility between US 287 and LCR 3 that would meet the following needs: 1. Improve current and future traffic mobility 2. Improve transportation safety 3. Accommodate 2030 travel demand. Keywords: Studies, US Highways

US 6 Clifton Access Control Plan

Region 3 of the Colorado Department of Transportation (CDOT) and Mesa County have identified a need to improve future traffic operations on US 6 between the I-70 Business Loop and the railroad viaduct east of 33 Road by developing an access management plan (AMP) . This ACP evaluated the portion of the US 6 corridor located from the Interstate 70 (I-70) Business Loop to the viaduct over the Union Pacific Railroad east of 33 Road. Keywords: Studies, US Highways

US 34 Finding of No Significant Impact (FONSI)

July 2007 - 6.5MB - This project encompasses approximately 6 miles of US 34 (also known as Eisenhower Boulevard) in Loveland, Colorado. The project corridor extends between a western terminus at US 287 (North Lincoln Avenue and North Cleveland Avenue one-way pair) and an eastern terminus of Larimer County Road 3 (LCR 3), 1.5 miles east of the I-25 interchange.

US 385 High Plains Corridor

Development and Management Plan - The High Plains Highway is a 222-mile corridor that begins near Kit Carson and ends at I-80 in Nebraska. It was identified as a corridor connector in the Eastern Colorado Mobility Study. The High Plains Highway Corridor Coalition (HPHC) – a formal association of towns and counties along the corridor - asked the Colorado Department of Transportation (CDOT) to assist the member communities in developing a plan for the corridor to anticipate and prioritize future corridor transportation needs.

US 50 Access Control Plan

US 50 is an important resource for the communities of Colorado's Western Slope. Traffic volumes on US 50 are projected to significantly increase in the future. One of the best ways to keep the highway safe and efficient is to manage the location and design of intersections and driveways (access points). This ACP evaluated the portion of the US 50 corridor located just west of Grand Mesa Avenue to SH 141A in Whitewater. Keywords: Studies, US Highways

SH 392 Environmental Overview Study (EOS)

The desired outcome of the EOS is to identify a transportation solution that has the support of local and regional planning partners, and which identifies ROW that must be preserved for those improvements. This plan would then be used by planners to set aside ROW as development occurs along the corridor. The SH 392 EOS study limits are from SH 287 on the west to Weld County Road (WCR) 23 on the east.

SH 392 Access Control Plan

October 2006 - Recent and continued growth in along Interstate (I) 25, State Highway (SH) 392, and within the local communities that make up the North Front Range, has resulted in an increase in traffic on the SH 392 corridor. Traffic volumes in the area are expected to at least double in the next 20 years. Without changes to the corridor, this increase in traffic volumes will result in increased delay, higher levels of congestion, and an increase in the severity and number of accidents. The Colorado Department of Transportation (CDOT) has identified the need for an Access Control Plan (ACP) on this corridor to minimize the occurrence of these conditions.

SH 60 Environmental Overview Study

The Colorado Department of Transportation (CDOT), Region 4, initiated an Environmental Overview Study (EOS) to evaluate the transportation needs along State Highway 60 (SH 60) from I-25 to Two Rivers Parkway in Weld County. Keywords: Studies, State Highways

SH 60 Access Control Plan

Access control plan was conducted in coordination with the SH 60 Environmental Overview Study. Keywords: Studies, State Highways

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, State Highways

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.”

Ports to Plains

This study was a joint effort by four state Departments of Transportation (DOTs) including Colorado, Texas, Oklahoma, and New Mexico. It includes I-70 from I-25 east to US 40/287 and then south along US 40/287 to the Colorado/Oklahoma border. The purpose was to create a Development and Management plan for the Ports to Plains Corridor, which outlines a proposed plan for the corridor and serves as an essential tool for securing federal funding for corridor development. It contains several elements that improve the transportation network’s ability to move people and goods. Nearly 1,400 miles long, the corridor consists of 511 miles of 4- to 6-lane roadway, 755 miles of 2-lane roadway, and 113 miles of roadway in metropolitan areas.
