The Soy Transportation Coalition (STC) recently published, “Heavier Semis: A Good Idea?” – a study analyzing the likely results of expanding semi weight limits over the federal highway system.

The study compares and contrasts the potential impact of the current 80,000-lb., five-axle semi configuration and an expanded 97,000-lb., six-axle configuration on three areas: motorist safety, infrastructure integrity and cost savings and efficiency gains for the soybean industry.

The goal of the study is to highlight whether expanding semi weight limits is a viable and common-sense approach for enhancing transportation capacity and mitigating highway congestion.
