As highway construction continues to cause strain to the national roadway system, initiatives and processes will be sought to remedy disruptions. The Accelerated Construction Technology Transfer (ACTT) process is one initiative that encourages the use of innovative technologies and methods to accelerate the construction of major highway projects for the purpose of reducing user delay and community disruption. ACTT was developed by Transportation Research Board (TRB) task force A5T60 and is now adopted and encouraged by the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) Technology Implementation Group (TIG). For its ACTT Workshop, the Montana Department of Transportation (MDT) selected the US-93 corridor between Evaro and Polson, in Western Montana. The $100 million project is to reconstruct this 90-km (56 mi) stretch of US-93 to upgrade the facility to todays design standards and add capacity. The project is somewhat unique, for it is entirely located within the Flathead Indian Reservation, the homeland of the Confederated Salish and Kootenai Tribes (CSKT). The Tribes recognize these lands as their homeland as well as the homeland for a variety of wildlife. The biggest challenge the project presents is upgrading to best accommodate traffic demands while minimizing impact on wildlife and other culturally sensitive issues. Another primary challenge is construction under traffic to ensure minimized disruption of tourist traffic, which peaks during the short construction season. The workshop was conducted on January 26-28, 2004, in Missoula, Montana. |
