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.
