| 摘要： | The State of Kansas has approximately 25,464 bridges that are located on the state, county and city roadway network. As the infrastructure in Kansas ages, bridges can become structurally deficient or functionally obsolete. The Kansas Department of Transportation (KDOT) defines a bridge as structurally deficient if an inspector determines the bridge deck, superstructure, substructure, culverts and retaining walls are not able to support today's federal legal loads (KDOT, 2008). A bridge that is defined as functionally obsolete consists of design characteristics, which could include narrow width, inadequate clearance beneath, condition of the structure, or deficient approaching roadway alignment (KDOT, 2008). Limited research has been performed that specifically investigates advantages and/or disadvantages of closing a bridge on a rural low volume road. The objective of this research project was to determine a cost comparison of replacing and/or repairing a rural low volume structurally deficient bridge, versus closing the same bridge and finding the change in vehicle operating cost based on the proposed driver detour. |
