Five parkways in Western Kentucky are located in the region that is greatly influenced by the New Madrid and Wabash Valley Seismic Zones. This report executes a preliminary screening process, known also as the Seismic Rating System, for bridges on and over parkways in Western Kentucky to identify the seismic vulnerable bridges.
The ranking of bridges derived from this rating system is based on: structural vulnerability, seismic and geotechnical hazards, and bridge importance. There are 349 bridges were ranked with the Seismic Inventory of Bridges (SIB), a user-oriented database program developed according to the Seismic Retrofitting Manual. The bridge ranks (R) range from a low of 0 to a high of 75, based on a scale of 100.
According to the seismic rank and regularity of bridges on and over the parkways in Western Kentucky, there are a total of 17 bridges, including parallel bridges, were selected for detailed seismic analysis. The 17-bridges have an average ranking of 58, with a highest bridge rank of 75.
