Gallatin County is currently the fastest growing county in Montana. Its population grew by 41% between 1990 and 2002 and by 5% between 2000 and 2002. This rapid growth has also led to accelerated deterioration of the transportation infrastructure. A well maintained transportation system is essential to regional economic growth, better traffic flow and safety. The Greater Bozeman Transportation Coordination Committee has completed “Greater Bozeman Area Transportation Plan Update 2001”. The update is the first step toward developing a countywide transportation plan. The work called for in this Proposal will supplement existing Bozeman and Belgrade transportation plans, serve as the basis for developing a countywide transportation plan, and identify a financial plan for immediate and forecasted transportation needs. The transportation infrastructure addressed in this Proposal includes pavements and bridges. Objectives of the proposed work are fourfold:1. Evaluate current condition of the transportation infrastructure;2. Evaluate condition of the transportation infrastructure reflecting future land use and traffic volumes in the County ;3. Estimate the cost of implementing recommendations of the final report resulting from this Proposal; and4. Recommend potential funding alternatives and schedules for implementing recommendations in the Final Report.
