City Island New Access provides pedestrian and bicycle access to the 63-acre City Island on the Susquehanna River via the Market Street Bridge and Walnut Street Bridge (pedestrian/bike only).

The island offers a marina for unpowered boats like kayaks and canoes, plus recreational amenities including trails, a riverboat society offering cruises, and the Susquehanna River School for water-based activities.

Note that boater access under the bridges is maintained, though construction on the Market Street Bridge is planned from 2027-2034 with temporary impacts to access.
