Developing the ramp is the first phase of construction for the years-in-the-making Reading Viaduct Rail Park, which has picked up steam recently with a $1 million grant from the Knight Foundation. Plans for the property, which is a quarter-mile long, were developed by Studio Bryan Hanes, the landscape architecture firm responsible for Sister Cities Park on the Benjamin Franklin Parkway as well as the Spruce Street Harbor Park that’s reopening later this month.

The Center City District is raising money to complete the planned improvements on the first phase of the project. The group has raised about 65 percent of the $9 million it needs for the SEPTA spur, and is pursuing a $3.5 million grant from the state’s Redevelopment Assistance Capital Program (RACP), according to John Struble, of Friends of the Rail Park. After the improvements are completed, the city would take over ownership of the park.

SEPTA’s board of directors must also approve the sale of the property. A spokesman for SEPTA said the sale has not yet been scheduled for a board vote.
