The Idaho Transportation Board Subcommittee on 129,000 Pound Truck Routes was established in 2013 to address legislation related to gross vehicle weights up to 129,000 pounds. The Subcommittee’s charge was to develop the process to allow 129,000 pound gross vehicle weights on additional state routes and then to review requests for these additional routes and make a recommendation to the full Idaho Transportation Board. Subcommittee meetings will be held on an as-needed basis.
Prior to July 1, 2013, trucks configured to increase gross vehicle weights from 105,500 pounds to 129,000 pounds were permitted on a select number of state highways in southern Idaho via a pilot project. Legislation approved in 2013 made those 35 specified routes permanent and provided authority to the responsible highway jurisdiction to allow gross vehicle weights up to 129,000 pounds on additional specified routes.
