L. 93–643, (2) analysis of alternative methods of determining gross vehicle weight limit and axle loadings for all types of motor carrier vehicles, (3) analysis of the bridge formula contained in 23 U.S.C. 127 in view of current vehicle configurations, pavement and bridge stresses in accord with 1986 design and construction practices, and existing bridges on and off the Interstate System, (4) establishment of nationwide policy regarding the provisions of ‘reasonable access’ to the National Network for combination vehicles established pursuant to Puspan. L. 97–424, and (5) recommendation of appropriate treatment for specialized hauling vehicles which do not comply with the existing Federal bridge formula and submit a final report to Secretary and Congress, not later than 30 months after appropriate arrangements were entered into.
