Book Description

Kansas State University conducted a study to identify and evaluate potential alternatives for marking narrow bridges. Based on the results of the literature review, the surveys of current practices and the field observations, several alternative signing strategies for low volume bridges were formulated. These alternatives include: 1) do not use object markers on low volume roadways, 2) reduce the height of object markers on low volume roadways, 3) stagger the object markers on low volume roadways, 4) use flexible sign supports, 5) use removable object markers, and 6) redesign the object marker and/or support. Implementation of such practices statewide could result in substantial cost savings to the highway agencies.
