    Seeking records of Pennsylvania Interstate Highway changes

    Stephan Summers Newbie

      Looking for documents concerning the Pennsylvania Interstate Highway Numbering changes from I-80S to I-76 in the early 1960s. I have route numbering history files from the FHWA and I am missing some information in regards to the request by Pennsylvania Dept of Highways to the FHWA in regards to the conversion of I-80S to I-76. This document also included several associated changes to the Interstate System in Pennsylvania. The documents are located in College Park under RG 406, finding aid UD-06D, Item #6.
