It seems the route change that was expected, I-376 being extended, did not take place as expected. However, it did not mean that the Pennsylvania road map was left unchanged after the opening of Interstate 99.
In December, PennDOT decided to truncate PA 82 at PA 23 in Elverson and renumber the remainder of the route in Chester County SR 4082. In Berks County, the route became SR 2082 north to Birdsboro and the PA 345 designation was extended to replace PA 82 to its northern terminus at US 422.
When Hurricane Agnes decimated Pennsylvania in 1972, it destroyed several bridges that carried PA 82 across Hay Creek south of Birdsboro. The Department of Transportation wanted to rebuild them but local opposition was strong as the residents who lived nearby became accustomed to the lack of traffic and wanted to keep it that way. PA 345 was signed that year as a detour route to bypass the missing section.
