Spring Load Restrictions (SLR) impose load restrictions on heavy trucks during the spring thaw period. Although the policies have been implemented for many years, we are still unsure of their economic effects on truckers. This paper overviews practices around the world and sets up a framework to estimate the Benefit/Cost of the SLR policy. A freight demand model in Minnesota was built to estimate the impacts of SLR on the freight transportation pattern. The model allows various policy scenarios to be tested before being tested in practice. A preliminary result of the freight demand model shows the SLR policy increased truck Vehicle Kilometers of Travel (VKT) in Lyon County, Minnesota by about 13 percent.
