During the three-month rehabilitation project, PennDOT’s contractor will utilize original salvaged stone to perform various masonry repairs, cleaning and repointing; install new guiderail and resurface the roadway and approaches. The original plaque on the structure will also be preserved. Built in 1789 and reconstructed in 1980, the Trinity Lane Bridge is the fifth oldest bridge in use in the United States and is listed on the National Register of Historic Places. The structure is 22-feet-long, 34-feet-wide and carries just over 7,000 vehicles per day. Due to the nature of construction, Trinity Lane (Route 320) will be closed and detoured 24/7 between Holstein Road and Balligomingo Road beginning Monday, May 10, through the completion of the project scheduled for mid-December. During the closure, Trinity Lane (Route 320) motorists will be directed to use Holstein Road, Swedeland Road and South Gulph Road. Local access will be maintained up to the construction zone.
