Service continued farther northwest, crossing the Schuylkill River via the massive Manayunk Bridge, and ultimately terminating at Ivy Ridge. This service ended in September 1986 when the integrity of the massive Pencoyd Viaduct was questioned. The massive span was shedding pieces of concrete due to spalling. Further investigation by Urban Engineers determined that the bridge was safe and only needed surface work to end the spalling. In 1999, construction finished on a project to stabilize and refurbish the bridge, but train service did not resume as expected.
SEPTA received criticism for refusing to reinstate service north of Cynwyd after the Pencoyd Viaduct was deemed safe. Plans to re-extend service floated around for approximately a decade until 2008 when SEPTA dismantled the line north of Cynwyd after leasing the line for the Cynwyd Heritage Trail and Ivy Ridge Trail, respectively.
