The Final EIS provides a detailed evaluation of the proposed transportation improvements along I-15 between the Montana City interchange and the Lincoln Road interchange and identifies a Preferred Alternative. The study area lies within the city of Helena, and in Lewis & Clark and Jefferson Counties, MT. The study area extends approximately 19 kilometers (12 miles) from Reference Post 187 to Reference Post 200. The Final EIS includes an examination of purpose and need, alternatives evaluated, travel demand, affected environment, environmental consequences, and mitigation measures as a result of the improvements under consideration. The identified Preferred Alternative (Alternative 1), Alternative 2 and a No-Action Alternative are presented in the Final EIS.

The Preferred Alternative (Alternative 1) is a composite of transportation improvements including a new South Helena interchange and a new northern interchange at Custer Avenue. This alternative is designed to optimize corridor transportation improvement without incurring undesirable environmental impacts. This alternative is enhanced by including five supporting elements to complete the proposed improvements. The major components of the alternative are:

  • New interchange at South Helena
  • Interchange improvements at Capitol
  • New interchange at Custer Avenue
  • Conceptual design for widening of Custer Avenue between N. Montana Avenue and N. Washington Street includes four travel lanes with a median/turn lane and bicycle/pedestrian envelopes. Final design will determine the exact configuration.
  • Construction of two auxiliary lanes (each direction) on I-15 between Custer Avenue and the Capitol interchange plus appropriate transitions for adding and dropping the auxiliary lanes (to be determined in final design).
  • Minor realignment of east side Frontage Road at Custer Avenue.
  • Replacement of the twin I-15 bridges over the Montana Rail Link railroad.
  • Supporting elements:
  • Montana City interchange improvements
  • Connect west side Frontage Road between Montana City and Colonial Drive
  • Broadway underpass for pedestrian and bicycle use
  • Widen Cedar Street to five lanes from I-15 to N. Montana Avenue
  • Lincoln Road interchange improvements

The FHWA, MDT, and other local agencies invite interested individuals, organizations, and Federal, State, and local agencies to comment on the evaluated alternatives and associated social, economic, or environmental impacts and mitigation measures related to the alternatives.
