Title: US Highway 93 Ninepipe/Ronan improvement project
Description: "The proposed action is the improvement of an 18-kilometer (11.2-mile) segment of US 93 from Dublin Gulch Road/Red Horn Road through the City of Ronan to Baptiste Road/Spring Creek Road in Lake County, Montana.  The improvements are proposed to provide a facility that meets current design standards in order to enhance the safety and operation of the facility.  A No-Action Alternative, and 10 widening alternatives are analyzed for the rural portion of the project, ranging from minor widening and improvement of the two-lane roadway with a cross-section of 12 meters (40 feet) to widening and improvement to a four-lane roadway cross section of 33.6 meters (112 feet).  This document also analyzes a No-Action Alternative and five action alternatives for the urban portion of the project through the City of Ronan.  These alternatives range from improving the roadway within the existing right-of-way to widening outside the existing roadway to a split couplet, with southbound lanes relocated to an adjacent street.  Alternatives Rural 3, a widened two-lane roadway with a single north bound climbing/passing lane on Post Creek Hill and a short four-lane divided section south of Ronan, and Ronan 4, a couplet with improved intersections and two lanes in each direction about a block a part, are the preferred alternatives.  In addition, a 3.0-meter (10-foot) wide separated pedestrian/bicycle path will be included for the entire length of the project as part of the preferred alternative."
