BUILT IN the 1890s, the Reading Viaduct carried workers on trains into Center City for nearly 100 years.
Rail service on the viaduct ended in 1984 with the opening of the Center City commuter tunnel that now carries trains into SEPTA's Market East station beneath the Gallery.
The viaduct section that crossed Vine Street was torn down for the construction of the Vine Street Expressway and Pennsylvania Convention Center. But the remaining viaduct, which is 4.7 acres, curves above 10 city blocks north of Vine on two separate elevated railway bridges.
