Between West 145th and West 135th streets waterfront access is not possible because of the North River Water Treatment Plant that sits on land built out over the Hudson River. Riverbank State Park sits atop the treatment plant but the greenway cannot be connected to it because bikes are not allowed in the park and the rooftop is elevated well above street level. DPR has created a striped inland route along the service road from 145th Street to 135th Street to bypass the gap.
