Reading Viaduct, Elevated park and former railway line in Philadelphia, United States

The Reading Viaduct, also known as The Rail Park, is a disused elevated rail line in the Callowhill district of Philadelphia that has been partly transformed into a public park. The first phase, opened in 2018, features a boardwalk, benches, swings, and plantings, while the rest of the structure remains largely overgrown and awaits further development.

The viaduct opened in 1893 as an approach to Reading Terminal and was used by the Reading Railroad until 1984. After decades of abandonment, the first phase of the park opened in 2018, following efforts by local artists and community groups.

The park's design draws inspiration from similar projects like the High Line in New York, and it hosts community events and art festivals. Local residents use the space for walking, relaxing, and enjoying views of the city, and the park is seen as a step toward greening a neighborhood that has few public green spaces.

The park is open daily and is free to enter. The entrance is at 13th and Noble streets, and the path is accessible for wheelchairs and strollers, though some sections may have uneven surfaces.

The viaduct cuts diagonally through the street grid, creating irregularly shaped lots and offering unusual views of the city. Before the park was built, the abandoned tracks were used by botanists to study plants that had taken root in the cinders.
