| Abstract: |
The design, construction and performance of two major Lehigh Valley PA highways are presented as well as special geohazard mitigation measures that were developed for I-78 based upon the PA-33 sinkhole history. The geologic setting, sinkhole history, and subsurface conditions of both I-78 and PA-33 are compared and contrasted. An update of the PA-33 sinkhole activity is presented along with proposed sinkhole mitigation measures currently under consideration. Sinkhole risks posed by planned residential development along I-78 are highlighted along with plans for an expanded Schantz Spring groundwater protection program. |
