Summary

J-U-B ENGINEERS performed an alternative solutions analysis for ITD District 6's US 20 Sheep Falls to Island Park Lodge projects, aiming to improve safety, mobility, and restore the roadway. The analysis considered existing conditions, traffic, and crash history, revealing a need for improvements due to poor level of service (LOS) and high accident locations. Proposed improvements include adding passing lanes and widening shoulders. However, the estimated $105,619,000 cost for a "full build" alternative exceeded available budgets, prompting a prioritization of passing lane locations based on criteria such as LOS, travel speed, crashes, grades, and wetland impacts. The top-ranked segments were selected for passing lane implementation, with one northbound and one southbound segment chosen for each of the three projects.
