The Federal Highway Administration (FHWA) and the Colorado Department of Transportation (CDOT) have prepared this Environmental Assessment (EA) documenting analysis under the National Environmental Policy Act for the Twin Tunnels project. The purpose of the project is to improve eastbound highway safety and mobility in the Twin Tunnels area of Interstate 70 (I-70) in Idaho Springs and Clear Creek County, Colorado. FONSI included.

The Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA) in coordination with the City of Grand Junction, Mesa County, and the Regional Transportation Planning Office (RTPO) are considering improvements to the I-70B Corridor in Grand Junction, Colorado. The I-70B West study corridor is approximately four miles in length and extends from 24 Road on the west to 15th Street on the east. Keywords: Studies, Interstates
The proposed I-76 and Bridge Street Interchange Project is located in Brighton, Colorado, in Adams County. The City of Brighton proposes to construct an interchange at I-76 and Bridge Street on the eastern side of the city. The proposed interchange would provide an opportunity to increase regional east-west connectivity across State Highway 7. This regional connectivity will become increasingly important with future population growth and increased travel demand. Keywords: Studies, Interstates

2007 - The Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT) and the City and County of Denver (CCD), is proposing to add a third northbound lane and a raised median, along with other improvements, to Federal Boulevard between Alameda Avenue and the 6th Avenue eastbound on-ramp.

The Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), has prepared this Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) to identify and assess a new alignment for U.S. Highway (U.S.) 287 and U.S. 50 through the City of Lamar, Colorado in Prowers County.

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 Colorado 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.

September 2004 - Environmental Assessment (EA) - The Federal Highway Administration (FHWA) in conjunction with the Colorado Department of Transportation (CDOT) has been conducting studies to investigate alternatives that would improve mobility (travel conditions) and safety on the stretch of approximately 2 miles of US 287 between SH 1 and the LaPorte Bypass intersection east of the town of LaPorte, mileposts (MP) 348.50 and 350.35. June 2006 - Finding of No Significant Impact (FONSI) - This document contains a FONSI and selects Preferred Alternative A4 with Reduced Footprint based on the analyses and results in the attached EA.

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.

Environmental Assessment (EA) - July 2007 and Finding of No Significant Impact (FONSI) - January 2008- encompasses the 4-mile length of SH 402 although improvements are not needed for the area between SH 287 and CR 13C (St. Louis Avenue), which was widened by developers in coordination with the city of Loveland and the Colorado Department of Transportation (CDOT) under a Categorical Exclusion (CE).

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
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.
