Rich in mining history, the Mountain Mineral Belt design segment rises from the foothills. Dotted with historic towns including Idaho Springs and Georgetown, the Mountain Mineral Belt offers scenic views, lush forests, rocky hillsides, waterways, and access to local and regional destinations and recreational opportunities. The Mountain Mineral Belt design segment contains five Areas of Special Attention (ASA) including Floyd Hill, Twin Tunnels; Idaho Springs; DLD and Empire Junction; and Georgetown and Silver Plume.
The Tunnel Visioning Design Workshop is the result of state and local interest in the I-70 Mountain Corridor and a desire for improvements to the existing weekend congestion. A focal point of the congestion and delay has long been the Twin Tunnel area. The Twin Tunnels encourage drivers to slow down as they approach the seemingly narrow tunnels. These slowing vehicles create a queue stretching back, sometimes, for 4 and 5 miles. It was decided to bring together technical experts in the areas of tunneling, roadway design, geotechnical engineering, traffic operations, and transit design for 1 week. The process, participants, and the results are detailed in this report.
The Colorado Department of Transportation (CDOT) initiated this US 24 PEL Study to examine existing transportation conditions and anticipated problem areas along the US 24 corridor in El Paso County between Powers Boulevard and the Town of Ramah. The study identified and screened a reasonable range of potential transportation improvements to develop an implementation plan for projects to meet the operational, safety, and capacity needs along the corridor. The study was conducted following Federal Highway Administration (FHWA) PEL guidance regarding the integration of transportation planning and the National Environmental Policy Act (NEPA) process, which encourages the use of planning studies to provide information for incorporation into future NEPA documents.
The Colorado Department of Transportation (CDOT) initiated a Planning and Environmental Linkages (PEL) Study to develop a range of improvements to reduce congestion and improve operations and safety at the I-70 and Kipling Street interchange. A thorough and inclusive technical and public process helped to identify and screen a wide range of improvement alternatives.
A PEL Study to provide an understanding of the existing conditions at the Interstate 70 (I-70) and Kipling Street (State Highway 391) interchange while considering future surrounding development and community plans. This Environmental Scan Report identifies environmental resources and environmentally sensitive areas; this is mostly comprised of readily available data and field survey information. The purpose of this scan report is to identify resources early in the planning process to avoid fatal flaws and to consider sensitive carry them through project development, design and construction.
The purpose of this paper is to provide a summary of a Value for Money analysis completed by the Colorado Department of Transportation (CDOT) and its High Performance Transportation Enterprise (HPTE) to evaluate options to construct and finance the first phase of the I-70 East project. A Value for Money analysis compares key quantitative and qualitative factors with a goal of determining the project delivery option that best fulfills CDOTs objectives, including the objective of building an affordable project on I-70 East from I-25 to I-225.
The Front Range Foothills design segment begins the accent to the Rocky Mountains from the eastern plains and the Denver metropolitan area. Significant features comprise of the hogback, scenic views including to the Continental Divide, Clear Creek, access to local and regional recreational opportunities, and communities and residential areas. The Front Range Foothills design segment contains one Area of Special Attention (ASA) at Floyd Hill.
Characterized by rocky hillsides, canyons and montane landscape, the Western Slope Canyons and Valleys design segment is a clear transition from the alpine landscape of the Crest of the Rockies. This design segment connects the towns of Wolcott, Eagle, Dotsero and Glenwood Springs and provides scenic views of the native vegetation, rocky hillsides and Colorado River, and provides direct access to local and regional recreational destinations. The Western Slope Canyons and Valleys design segment contains two Areas of Special Attention (ASA) including the East Entrance to Glenwood Springs and the Wolcott Curves.
