Bridgeport Viaduct Improvement Project Recap

Over the last four months, construction crews worked to replace deteriorated bridge timbers across the 3,185-foot Bridgeport Viaduct.

The Norristown High Speed Line Viaduct, built in 1911, was last rehabilitated in 1985. This latest rehabilitation project included replacement of all bridge timbers through the open deck portion of the structure, and all ties, and ballast through the closed deck sections.

The work also included:

Localized structural steel and rivet repairs

Localized structural cleaning and painting

Waterproofing the closed deck portion

Installing new cable tray

Replacing all of the power, signal, and communications cables

Replacing the existing open deck walkway with new fiberglass walkway

Installing new safety railings on open deck walkway

While the completion of this project enables SEPTA to continue to maintain safe train operations between Bridgeport and Norristown, an extensive structural rehabilitation program for this Viaduct is needed in order to bring the bridge into a state of good repair and extend its service life by another 40 years.
