Tunnel visioning : a design workshop for the twin tunnels
Tunnel visioning : a design workshop for the twin tunnels
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., "March 2011.", Description based on online resource; title from PDF cover (viewed September 2013)

The Twin tunnels project proposes to add a third eastbound travel lane on I-70 between the Idaho Springs East Interchange (milepost 241) to the base of Floyd Hill (milepost 244) where a three-lane highway section currently exists. The project is approximately two and a half miles long and includes widening the eastbound bore of the Twin tunnels., by the U.S. Department of Transportation , Federal Highway Division Administration, and Colorado Department of Transportation., [Vol. 1]: Twin Tunnels environmental assessment and section 4(f) evaluation Clear Creek County -- [vol. 2]: Twin Tunnels portal to portal access road, companion report to the Twin Tunnels environmental assessment and section 4(f) evaluation., CDOT Project C0703-379., Description based on print version record.

The Twin Tunnels project will add an additional lane of highway capacity and improve roadway geometry for about 3 miles of eastbound I-70 from the East Idaho Springs Interchange (milepost 241) to the base of Floyd Hill (milepost 244) where the project ties into an existing three-lane section. The eastbound bore of the Twin Tunnels will be expanded to accommodate the widened roadway section., Introduction -- Proposed action -- Summary of impacts, mitigation measures, and permit requirements -- Updates and clarifications to the environmental assessment -- Coordination and response to comments -- Updates and clarifications so the section 4(f) evaluation -- Selection of the preferred alternative -- Finding of no significant impact -- List of tables -- List of figures -- Appendix., "October 2012."--Cover., "CDOT Project Number C0703-379."--Cover., Description based on print version record.

US 34 planning and environmental linkages (PEL) study
This report documents the results of a Planning and Environmental Linkages (PEL) Study for US Highway 34 (US 34) between Larimer County Road (LCR) 29 and Weld County Road (WCR) 53 within Larimer County; Weld County; the Cities of Evans, Greeley, and Loveland; and the Towns of Johnstown, Kersey, Garden City, and Windsor. US 34 is a critical east-west transportation corridor for northern Colorado's growing communities. Sustained and strong economic development along US 34 has increased, and travel demand has necessitated the need to enhance safety, reduce congestion, and improve mobility., prepared for Colorado Department of Transportation, Region 4 ; prepared by CH2M in association with: Tsiouvaras Simmons Holderness, Stolfus., text file, "January 2019.", Project # NH0341-091,21444.

US 50 corridor east tier 1 final environmental impact statement and record of Decision : from the City of Pueblo, Colorado, to the vicinity of the Colorado-Kansas state line
The U.S. Highway 50 (US 50) Tier 1 Environmental Impact Statement (EIS) is a 150-mile broad-scale transportation study from approximately the city of Pueblo, Colorado, to the vicinity of the Colorado-Kansas state line. The corridor traverses four counties and 10 municipalities providing local and regional connections for the distribution of people, goods, and services through and beyond the Lower Arkansas Valley. The purpose for undertaking transportation improvements in the US 50 corridor is to improve safety and mobility for local, regional, and long-distance users of US 50 for present and future travel demand., submitted pursuant to 42 USC 4332(2)(c), 49 USC 303, and 23 USC 138 by the U.S. Department of Transportation, Federal Highway Administration and Colorado Department of Transportation ; cooperating agencies U.S. Army Corps of Engineers, U.S. Environmental Protection Agency ; participating agency U.S. Fish and Wildlife Service., "December 2017.", Online resource; title from PDF caption (viewed January 2019)
