MDT Initiates US 89 Corridor Study

July -August 2013

The Montana Department of Transportation (MDT), in partnership with the Federal Highway Administration (FHWA) and in coordination with Park County, is developing a corridor planning study of US Highway 89 (N-11). The study will examine the highway from reference post (RP) 0.0 at the Yellowstone National Park (YNP) boundary in Gardiner, north to RP 52.5 south of Livingston.

The study will identify feasible improvement options to address safety and geometrical concerns within the transportation corridor based on needs presented by the public, the study partners, and resource agencies. The study will examine geometric characteristics, crash history, and existing and projected operational characteristics of the corridor. Existing and projected physical constraints, land uses, and environmental resources will also be analyzed.

The study will include a package of short- and long-term recommendations intended to address the transportation needs of the highway over the planning horizon (year 2033). These recommendations will assist the study partners in targeting the most critical needs and allocation of resources.
