Geohazards in East Tennessee:
Examples of Highway Development in Karst Areas
Harry L. Moore
(Retired TN DOT Geologist)
Designing and constructing a
stable highway infrastructure across karst can be quite
challenging and requires an in depth study of the karst regime.
Planning new roadway corridors can be aided by the mapping of
karst areas and karst features. Subsidence, collapse, flooding
and groundwater contamination tend to be the major hazards
associated with the karst landscape. Proactive approaches
regarding karst geohazards include avoidance, minimizing impact,
East Tennessee, with its abundance of carbonate strata, hosts numerous areas of karst including features such as sinkholes, caves, sinking streams, and numerous subsurface streams. Karst landscapes in East Tennessee tend to be linear in shape, mimicking the structural trend of the regional bedrock. Most of the East Tennessee karst is developed in the Valley and Ridge province and is generally elongate parallel to the strike of the folded strata, most typically a northeast-southwest trending pattern.
A number of the caves in East Tennessee are quite large and display beautiful speleothems as well as an abundant cave life. In addition, subsurface streams can be found in a large number of the cave systems.
