Abstract
Thornton is a small town in Eastern Idaho located approximately five miles from Rexburg. The Thornton Interchange Project replaces an unsafe, at-grade intersection—that currently experiences great number of vehicle accidents—with an overpass and interchange. More than 21 accidents have resulted since 2000 from vehicles attempting to cross four lanes of US-20. The Thornton Interchange project includes a pre-stressed concrete bridge designed to carry US-20 and allow vehicles to safely cross underneath the highway. Other project elements for a new, full interchange—centered on durability and safety—include on-off ramp design, new roadway alignment designs, pavement design, and environmental impact assessment.
