The Transportation Expansion Project or T-REX was a $1.67 billion venture that had a goal of transforming the way people in the metro Denver area commute within the areas of Interstates 25 and 225, then the country's 14th busiest intersection. The T-REX effort widened major interstates to as much as 7 lanes wide in each direction and added of double-track light rail throughout the metropolitan area (40 miles total). It's considered by some to be one of the most successful transportation upgrade projects in the United States.〔Colorado DOT- T-REX takes top awards at national contractor convention, http://www.dot.state.co.us/Communications/News/DM2007TREX.pdf〕〔Associated General Contractors of America- Presents First-ever Grand Award to Nation's Top Project at AGC's 88th Annual Convention, http://www.agc.org/galleries/pr/07-025.doc〕〔US Department of Transportation, Environmental Review Toolkit, http://www.environment.fhwa.dot.gov/strmlng/casestudies/index.asp〕〔 T-REX team is 2004 award recipient,http://findarticles.com/p/articles/mi_m3724/is_5_68/ai_n14712958〕 It also received a National Design-Build Award from the Design-Build Institute of America.〔Design-Build Award Competition Winners, http://www.dbia.org/awards/Pages/Project-Awards.aspx〕 The T-REX project finished 3.2% under its $1.67B budget and 22 months ahead of schedule in 2006〔Metro Denver Development, Transportation Infrastructure, http://www.metrodenver.org/DataCenter/Infrastructure/〕 and is considered to be an example of inter-governmental agency cooperation for transportation projects for North America and Worldwide. Stakeholders have been recognized nationally and internationally for its success, including quality management.〔International Road Federation, IRF recognizes Colorado's Transportation Expansion Project (T-REX) as world class in Quality Management, http://www.irfnews.org/trex_press_release.htm〕 Success in T-REX led to public support of FasTracks during the 2004 election.〔What is FasTracks?, http://www.rtd-fastracks.com/main_26〕 The T-REX corridor carries more than 280,000 vehicles per day and connects the two largest employment centers in the region: Downtown Denver and the Denver Tech Center. ==Funding== T-REX was funded using no new state, county, city, or gas taxes. This was partially due to the TABOR laws enacted in 1992, and the State Leadership's stance against levying additional taxes on its constituents.〔Federal Highway Administration, "Colorado's T-REX: Mega, Multi-modal, Design-Build" http://www.fhwa.dot.gov/hfl/successstory.cfm?id=5〕〔Bill Owens Memorial Highway? Why not?, http://www.rockymountainnews.com/drmn/business_columnists/article/0,1299,DRMN_82_5260446,00.html〕 Instead, metropolitan areas that would benefit from the expansion voted to approve an increase of property taxes required for the build out. In November 1999, voters in affected municipalities approved two property-tax increases which partially funded the transit portion of the project. Among those : * Design-build contract with Southeast Corridor Constructors worth $1.18 billion. * Light rail costs: $879 million, with $437 million coming from RTD and local matching funds; $525 million from an FTA full-funding grant agreement.〔T-REX Project Factbook, http://www.metrodenver.org/documents/T-REX%20Factbook.pdf〕 * Highway costs: $795 million, from highway users taxes and matching federal revenue.〔SPG Media PLC/RoadTraffic Technology, http://www.roadtraffic-technology.com/projects/trex/〕 * 34 new light-rail vehicles: $91.8 million. * Elati Street Light Rail Maintenance Facility: $39.5 million. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Colorado T-REX Project (TRansportation EXpansion)」の詳細全文を読む スポンサード リンク
