"I can't believe City Hall is gone," said Philadelphia area rider and BMX videographer Ryan Navazio via Twitter. "So much time spent there over the years, hanging out, riding and filming."

The plan, which will last 27 months and cost $50 million, will transform the area, located at 15th and Market Street west of City Hall, from a multi-level, hard-surface plaza into a sustainable, green public space with no stairs or barriers from the street. According to the Central Philadelphia Development Corporation, "the renovated Dilworth Plaza will add 20,571 square feet of new useable area (an increase of 21%) and will result in an expanded 120,557-square-foot public space. The new plaza will have a large lawn, tree groves, a programmable fountain and space for 400 benches and chairs."

The area, formerly a home to the the Occupy Philadelphia movement as well as the city's homeless throughout the years, has served as one of the main meeting and warm-up spot for skateboarders and BMXers in the Philadelphia area since the '90s. In terms of BMX videos, Dilworth Plaza was featured in countless videos from the Dorkin In York series, Animal Bikes, Federal Bikes, Standpoint, Standard Byke Co., and more. And riders that left their original mark on the plaza include Garrett Reynolds, Corey Martinez, Brian Wizmerski, Josh Stricker, Edwin De La Rosa, Bob Scerbo, Steven Hamilton and Rick Moliterno.

The plaza was also home to an X Games skateboard street contest in the early '00s while the X Games was based in Philadelphia.
