While I don't speak on behalf of the Senator, here is part of our campaign.
"It is our intention to raise weight limits on Maine's highway system to increase safety on our secondary roadways as well as decreasing wear and tear on the same infrastructure.
Here are studies that support our cause:
A detailed analysis by Wilbur Smith Associates, completed in 2004, considered impacts on Maine’s entire transportation system. The study estimated a savings of $1.0 to $1.7 million per year in pavement rehabilitation costs and more than $300,000 in annual bridge maintenance and rehabilitation savings if the federal weight exemption currently in place on the Maine Turnpike were to be extended to all of Maine’s Interstate Highways.
A 2004 Wilbur Smith study noted that the crash-rate experience of five- and six-axle combination trucks was seven to ten times higher on Maine’s non-Interstate highways than on the Maine Turnpike, which is currently exempted from federal weight limits
Allowing the use of loaded six-axle combination trucks on the Interstate would increase payloads by nearly 35 percent over that carried by the five-axle combination truck, thereby reducing the number of trucks needed to transport given levels of commodity and reducing the overall impact on Maine’s transportation infrastructure
According to the ATRI report, a comparison of a vehicle with a gross vehicle weight (GVW) of 100,000 pounds over two different routes (an Interstate route versus a state highway route) identified trip-level fuel efficiency improvements, measured in miles per gallon, of 14 to 21 percent when traveling over the Interstate route. Trip-specific emissions were also estimated to decrease by 6 to 11 percent for carbon dioxide (CO2) and 3 to 8 percent for particulate matter (PM) and oxides of nitrogen plus non-methane hydrocarbons (NOx + NMHC) over this route
Correlating the ATRI findings with the 2004 Wilbur Smith study results in a potential daily savings of approximately 194 gallons of fuel, a reduction of 2 metric tons of CO2 emissions and reductions of 60 pounds of NOx _NMHC emissions "

Senator Collins: "Collins said her favorite example drew comparisons between a truck traveling on U.S. Route 2 versus one traveling on Interstate 95 from Hampden to Houlton. First, the interstate would save the trucker 50 minutes and an estimated $30 in fuel costs. Second, the truck trav-eling on secondary roads would encounter nine school crossings, 30 traffic lights and 86 crosswalks."
"Despite widespread support across Maine, easing the federal truck weight limits has considerable opposition from national highway safety groups and the powerful railroad industry lobby."

"According to national statistics, 82 percent of commercial vehicle fatalities occur on non-Interstate roads. By allowing heavier trucks on the limited-access Interstate, the traffic is removed from towns and cities and smaller roads, where they pose a greater risk.
Moving heavy traffic to the Interstate is also expected to reduce wear-and-tear on Maine’s secondary roads and reduce bridge and pavement repairs by as much as $2 million per year."
