MTA Bridges and Tunnels Construction Improvements
- Robert F. Kennedy Bridge
- Verrazano-Narrows Bridge
- Bronx-Whitestone Bridge
- Henry Hudson Bridge
- Throgs Neck Bridge
A three-year, $33 million project is underway to replace the original 1930s steel curb stringers that support the upper level roadway on either side of the bridge. In addition to replacing the stringers and installing 3,600-feet of new bridge decking, new energy-efficient roadway lighting will also be added. The new space will be re-striped, resulting in wider traffic lanes across the bridge.

A 42-month, $109 million reconstruction of the Queens approach to the bridge is underway. The contract was awarded jointly to E.E. Cruz, of Manhattan, and Tully Construction Co., of Queens in July 2011. The work includes reconstruction and widening of the 1,010-foot-long Queens approach roadway and the addition of new safety shoulders. The children's playground beneath the bridge in Francis Lewis Park has already been moved from beneath the bridge and completely renovated, thanks to B&T. It reopened in May 2012.

A two-year, $47 million project to paint and rehabilitate 2.5 million square feet of steel on the Bronx approach of the bridge began in June 2012 and is scheduled for completion in late 2014. Some 45,000 gallons of paint will be used in this phase of the project and when it is finished the bridge will be entirely free of all old, lead paint.
This is the last phase of an overall $100 million paint program at the Throgs Neck that began in 2006 and has included cleaning and repainting of the bridge span, both towers and the Queens approach structure.
Upper Level Roadway Work
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.

Upper Level Deck Replacement Project
The Verrazano-Narrows upper level deck reconstruction project is a five-year, $235.7 million Capital Construction project to replace the original 1960s concrete grid roadway deck with a new, lighter, longer lasting orthotropic deck.
Obsolete maintenance walkways on the bridge’s upper level will also be removed, providing enough space to add a new reversible HOV bus and car lane across the bridge, connecting the NYS Department of Transportation’s HOV lane on either side of the bridge for the first time. Once finished, the new HOV lane will provide a seamless trip from the Staten Island Expressway to Hugh L. Carey Tunnel, saving time for thousands of daily HOV users.
New LED lighting, new sign structures, painting and a new drainage system will also be added. The project is expected to be completed by late 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.
