The Pennsylvania Department of Transportation (PennDOT) invites the public to an in-person and virtual plans display regarding proposed Interstate 78 improvements in Upper Macungie and Weisenberg townships in Lehigh County.
According to a press release from PennDOT, the in-person public plans display will be held at the Fogelsville Elementary School (312 PA 100, Breinigsville, PA 18031) on May 6, 2026, beginning at 6:00 p.m.
Officials say the proposed improvements include the construction of a new interchange at Adams Road over I-78, the complete reconstruction of the I-78 and Route 100 interchange, and the complete reconstruction of mainline I-78 from the Berks/Lehigh County line to the U.S. 22 split.
The purpose of the project is to eliminate substandard features in the corridor, reduce congestion, and accommodate planned growth in the region, according to the release.
PennDOT says the virtual plans display will be available online, and public comments will be accepted from May 6, 2026, through June 5, 2026. Online information, including proposed detour route, detailed project information, and comment form, can be found by visiting the PennDOT District 5 website.
The project documents can be made available in alternative languages or formats if requested. Officials say if you need translation/interpretation services, have special needs, or have concerns requiring individual attention, contact Andrew Samy, P.E., PennDOT Senior Project Manager, at asamy@pa.gov.
