  8. P ROJECT B ACKGROUND PEIS R ECOMMENDATIONS • The Tier 1 decision included three basic elements: travel mode, capacity, and general location • Selected the Preferred Alternative, a long‐term 2050 vision for the Corridor that includes: • Non‐infrastructure components • An Advanced Guideway System • Highway improvements • Identified Highway Improvements for West Vail Pass: • EB and WB auxiliary lanes from mile markers (MM) 180‐190

  9. P ROJECT B ACKGROUND S IGNIFICANCE OF I-70 V AIL P ASS • Key freight corridor : I‐70 is the only contiguous east‐west interstate in Colorado on the National Highway System. • No resiliency : Travel detours are long and on 2‐lane mountain roads, between 1‐3 hours of additional travel time, and costly. • Critical for quality of life : I‐70 is the critical link for tourism and local economies between the Front Range and western Colorado.

  10. P ROJECT B ACKGROUND S AFETY C ONCERNS • High number of crashes Substandard geometry including tight curves • • Speed differentials resulting in sideswipes and rear end crashes • Narrow roadway impacts driver correction

  12. P ROJECT B ACKGROUND T RAFFIC O PERATION I SSUES • Safety issues lead to significant full road closures. With only two lanes, full closures are needed to maintain “Lane +1” for Safety. • Steep grades & tight curves with high number of slow‐ moving vehicles leads to erratic lane changes and speed differentials
