Bridges affected connect the Lincoln Drive and Forbidden Drive section of the Wissahickon Valley Trail that link between Forbidden Drive and Schuylkill River Trail. These trials got busier than normal during the pandemic when everyone was under lockdown. The Parks & Rec department say cyclists and runners will have to take detours through "steep slopes and soft surfaces." "Philadelphia's 184 miles of trails have been there for residents during the pandemic, and we are committed to ensuring they remain safe, well maintained, and accessible to all," Philadelphia Parks & Recreation Commissioner Kathryn Ott Lovell said. "This short term closure will deliver long term enjoyment for generations of commuters, hikers, and cyclists."
