TS&W REGULATION RESEARCH AND DEVELOPMENT ON THE WESTERN BORDER

Over and above the on-going activities of WASHTO, AASHTO, and NAFTA Land Transportation Standards Subcommittee consultations, there are a number of specific TS&W development and research projects underway of importance to trucking across the western border.

Canamex (Rocky Mountain Trade Corridor)

Alberta is promoting development of the Canamex trucking corridor involving Arizona, California, Idaho, Montana, Nevada, Utah, and the Federal Governments of Mexico and the United States. The latest version of the proposal is outlined in a “Memorandum of Understanding regarding the Canamex Trucking Corridor” circulated at an AASHTO Meeting in Phoenix in early June 1995. The proposal envisions undertaking a pilot project permitting the operation of A- and C-train Rocky Mountain Double trailer combinations along I-15 connecting to Highway 4 in Alberta and extending south to the U.S.-Mexico border at higher than current weights in order to enhance industry productivity. The TS&W details of the proposals are:

12,000 pounds

Single axle

20,000 pounds

Tandem axle

34,000 pounds

Gross vehiucle:
