This session will provide an overview of a study that was conducted by the Missouri Department of Transportation (MoDOT) and the Ozarks Transportation Organization (OTO) in order to evaluate the operational and safety needs of certain freeways in Springfield and to provide a prioritized list of projects to address those needs. The Springfield region has grown steadily for a long period of time and infrastructure, capacity, and safety needs along the freeways in the study have grown concurrently.
The study team examined existing conditions related to traffic flow, safety, roadway design, and bridge ratings. The team also developed traffic flow analyses for the year 2040 to identify future capacity needs. Based on these investigations, this study presents a series of recommended projects and includes conceptual drawings and cost estimates to assit with planning efforts.
Eighteen recommended projects were ranked two different ways: using a Benefit/Cost Ratio, and a Net Benefit estimate (monetized benefits minus costs). Ten of those projects appear to have a favorable benefit-cost ratio and include minor ramp improvements, turn lane additions, signal installations, roundabout installations, grade-separated interchanges with new frontage roads, and a braided ramp with interchange improvements. MoDOT and OTO can use these rankings and costs at a programming level to formulate the Statewide Transportation Improvement Program (STIP) and the Transportation Improvement Program (TIP).
