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.
