The primary objective of the TBTA's RK-23 project is to rehabilitate the steel approach structures and replace the concrete spans of the Manhattan Approach ramp structures to the Robert F. Kennedy (RFK) Bridge. This project focuses on the structures facilitating vehicular traffic to and from Manhattan, and facilitating pedestrian access to and from Randall's Island. The proposed work will bring the approach structures to a state of good repair, and provide a minimum 50-year service life.

B. Thayer Associates Landscape Architects and Architects are providing services which include Arborist Assessment, Permitting, and PS&E for Landscape Architecture and Architecture Restoration. Our Landscape Architects and Arborists completed a detailed tree inventory of all trees over four-inch caliper within the project area per New York City Department of Parks and Recreation (NYCDPR) standards. For the Design Brief Task, the tree inventory was submitted with a written Arborist report and cost estimate identifying trees impacted by the proposed work.

Our Landscape architects also produced documentation for the project’s New York State Historic Preservation Office (SHPO) application, photo documenting existing conditions and identifying proposed work. Upon TBTA and NYCDPR approval, tree removals and landscape restoration plans will be further developed.

All tree protection, removals and replanting will be coordinated with the TBTA, NYCDOT Arterial Maintenance, and NYCDPR Capital Forestry.
