Abstract
This project presents the geometric design and performance evaluation of a proposed highway corridor connecting Teton Pass, Teton Village, and Jackson Hole Airport in Wyoming. The study focuses on developing a safe, efficient, and environmentally sustainable roadway alignment in challenging mountainous terrain. The design follows AASHTO Green Book guidelines and incorporates key elements such as horizontal and vertical alignment, superelevation, corridor modeling, grading, intersection design, and bridge layout. Advanced modeling using Civil 3D was utilized to optimize alignment, balance cut-and-fill volumes, and minimize environmental impacts. The proposed design improves roadway safety, enhances connectivity, and supports sustainable transportation development in mountainous regions, particularly under varying seasonal and traffic conditions.
