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) is closed and detoured 24/7 between Holstein Road and Balligomingo Road, through the completion of the project scheduled for early August. 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.
Work on this project will be in accordance with Centers for Disease Control and state Department of Health guidance as well as a project-specific COVID-19 safety plan, which will include protocols for social distancing, use of face coverings, personal and job-site cleaning protocols, management of entries to the jobsite, special signage, and relevant training.
