MTA Bridges and Tunnels Construction Improvements
After nearly 80 years in the salty sea-air, the Marine Parkway-Gil Hodges Memorial Bridge is getting major upgrades and repairs to its lift span mechanical and electrical systems, structural steel and grid-deck repairs, bridge painting, and new fire line system and hydrants.

Upper Level Roadway Work
Contract VN80B of the Verrazano-Narrows Bridge deck reconstruction project will replace panels on the upper deck of the bridge.
This work is part of the five-year, $237.5 million Capital Construction project to replace the bridge’s original 1960s concrete, grid roadway deck with a lighter-weight, longer-wearing orthotropic deck. Demolition of the upper level roadway began March 16, 2015 with the removal of the center median, followed by sections of the old roadway. Using giant gantry cranes, the new roadway deck panels will be put in place, welded and bolted together and a waterproofing membrane and new asphalt overlay applied. Completion date is the end of 2017.

Upper Level Gantry Cranes
These photos show Contractor Tutor Perini installing a gantry crane system to help install the new, lighter, longer-wearing orthotropic deck. The work is part of the five-year, $237.5 million Capital Construction project to replace the bridge’s original 1960s concrete, grid roadway deck. The gantry cranes are supported by temporary girders installed along the full length of the bridge along each side of the roadway. The $3.9 million gantry crane system was manufactured near Boston and Philadelphia, and assembled at the site during night-time closures.

This 42-month, $84.3 million project includes the construction of a new Bus/HOV ramp that will connect the new Bus/HOV lane from the bridge to the Gowanus Expressway HOV lane in Brooklyn. In addition, two original Belt Parkway entrance ramps that connect to the main span of the Verrazano-Narrows will be rehabilitated and reconfigured. Construction of the new HOV ramp is taking place in open spaces on the Brooklyn side of the bridge. It involves constructing 25 new pier columns, ranging in size from 20 to 100-feet tall. Some structural painting and steel repair work are also included in the project. The project was awarded to El Sol, of Queens. The scheduled completion date is summer 2017.

Through 2019 motorists can expect to see plenty of activity at the sprawling, three-complex Robert F. Kennedy Bridge as MTA Bridges and Tunnels is spending nearly $1 billion in Capital improvements. The largest projects include reconstructing the supporting bridge structures at the Manhattan and Bronx toll plazas and rehabilitating and replacing the bridge’s seven ramps.
The RFK Bridge, which opened in July 1939, includes three bridges and 14 miles of roadways that merge at a junction structure on Randall's Island where traffic is distributed to and from Manhattan, Queens and the Bronx.

Some 400,000-square-feet of old asphalt at the Manhattan toll plaza was removed and replaced with a new, rubberized asphalt to help prevent water from seeping into the concrete deck. This $5.8 million project, completed in early 2012, provides a smoother riding surface for customers and will extend the life of the roadway until full reconstruction of the Manhattan toll plaza gets underway.

The 12,000-square-foot Harlem River Drive southbound exit ramp, which leads onto the bridge at East 125th Street, was completely rebuilt. A temporary ramp was put in place while the 50-year-old ramp was reconstructed. The $12.4 million project was completed in December 2011.
The Manhattan/Queens ramp at the Robert F. Kennedy Bridge is a $50.7 million design/build contract to reconstruct the ramp which was originally constructed in 1967. The contract was awarded in June 2012 to Halmar International of Pearl River, N.Y., and its design partner, Hardesty & Hanover. The construction management team was LiRo Group of Long Island. Work was completed in August 2014.
