Engineering Feasibility Study of the Future Extension of the Eisenhower-Johnson Memorial Tunnel (UTI-UTC 12)

This project conducts a comprehensive engineering feasibility study to assess potential future extensions of the Eisenhower-Johnson Memorial Tunnel (EJMT), a critical component of Colorado’s transportation network. The study integrates geological modeling, transportation planning, and structural engineering to evaluate the viability of new tunnel bores aimed at alleviating congestion and improving long-term capacity. Utilizing updated 3D geologic data and traffic projections, the research identifies and analyzes various tunnel alignment options, considering technical constraints, environmental impact, and economic factors. The project employs advanced geotechnical simulations and scenario analyses to support decision-making for design alternatives. Collaboration with the Colorado Department of Transportation (CDOT) ensures alignment with real-world planning needs. The outcome provides a foundation for strategic infrastructure investment and future tunnel development in high-altitude mountainous regions.
