Abstract

The Tennessee Department of Transportation (TDOT) has proposed a corridor for a bypass to the north and west of Knoxville referred to as SR 475, Knoxville Parkway. As part of the EIS study of the proposed corridor, a geologic/geohazards study was conducted by the TDOT Geotechnical Engineering Section. A result of this study was the identification of karst areas, caves, and sinkholes along the study route. A number of the caves that were found were surveyed to better locate the features vertically and horizontally with respect to the corridor. A number of the caves were mapped. The study corridor was shifted in places to avoid, where possible, the cave and sinkhole issues.

Mike Russell, TDOT project manager for the Knoxville Parkway project, will also be available at the meeting to answer questions regarding the project. For additional information, please see www.tdot.state.tn.us/sr475.
