This project involves the realignment and widening of Battery Place including construction of a structure over the FDR Drive Underpass as part of the NYSDOT’s Route 9A Segment 1 Project.

The structure will lengthen the Battery Park Underpass by approximately 40 feet, requiring upgrading of the mechanical, electrical and lighting systems for the tunnel.

Hardesty & Hanover served as the designer in charge of the electrical system upgrade for the FDR Drive Underpass, commonly referred to as the Battery Park Underpass. The scope of work performed by Hardesty & Hanover involved coordination of the ventilation requirements, design of the roadway lighting system, design of the fire detection system modifications, and design of the electrical and control system upgrades for the modified underpass.

Hardesty & Hanover developed design plans, technical specification and cost estimate package for project.
