Making the Connection: A New Ramp for Manhattan's Upper East Side

In Manhattan’s Upper East Side, a new flyover ramp is creating a critical new connection for New York City drivers and providing much-needed redundancy for an aging transportation network. The Robert F. Kennedy Bridge, built in 1936 as the “Triborough Bridge” and renamed in 2008 in honor of the late brother of 35th President John F. Kennedy, has connected the boroughs of the Bronx, Manhattan, and Queens as one of the city’s most vital pieces of transportation infrastructure. Until recently however, a noticeable piece of the puzzle was missing at the Manhattan end of the bridge – the lack of a direct connection to the northbound side of the Harlem River Drive highway, which serves to connect this area of Manhattan with the outbound side of the George Washington Bridge. Construction of this “missing” ramp movement was finally pursued (after more than 60 years of delay) in order to provide motorists originating from northwest Queens with an alternate, redundant path to the GW Bridge while also improving traffic circulation on the local street grid in East Harlem.


The Manhattan leg of the RFK Bridge features this vertical lift span over the Harlem River. The design of its lift towers intentionally mimics the appearance of the nearby George Washington Bridge.

For this project, cooperation between neighboring client agencies was essential for contract success. The RFK Bridge and its approach ramps fall under the jurisdiction of the Triborough Bridge & Tunnel Authority (TBTA, an affiliate agency of the broader Metropolitan Transportation Authority, or MTA), however the neighboring/underlying Harlem River Drive highway lies under the domain of NYSDOT, who had already begun a contract of their own to rehab the elevated section of the Drive north of the RFK Bridge approach. Under an agreement reached between TBTA & DOT officials, the scope and design of the Harlem River Drive rehab project incorporated the then-hypothetical ramp connection from the Manhattan-bound RFK lanes and the structures built were made modifiable in order to accommodate potential future construction additions.

Opened to traffic on November 23, 2020, the ramp itself is approx. 1,400 ft long, is supported by 17 vertical column piers, and stands at a max height of 50 ft above ground level. The project was built under a $48 million contract by Judlau Contracting and was funded under the MTA’s 2015-2019 Capital Plan. Other constraints that had to be taken in to account included the neighboring Harlem River and the Willis Avenue Bridge, a major artery for Bronx-bound traffic on the Upper East Side that itself had been replaced less than 10 years prior. All of the obstacles mentioned led to the creation of a snake-like path for this direct-connect flyover that will manage to improve travel times while also making good use of whatever available real estate there is.

The Harlem River Drive direct-connect flyover is also worth discussing due to the type of contract that saw its design & construction, a process known as “design-build”. Under a traditional project development timeline, a client & design firm will both agree on a proposed design for a project that is then bid and awarded for construction by a separate contractor. The “design-build” contract concept takes the design & construction phases and combines them, meaning that a single firm or joint venture inherits responsibility of both the design and construction of a project and there is significant overlap between these phases in the overall project timeline. While this method is intended to streamline and shorten the timeline for large-scale project delivery, it does also have the disadvantage of increased uncertainty when it comes to final contract pricing and scheduling. The design-build phenomenon is a relatively new one and it became a reality in New York State in 2011 when Gov. Andrew Cuomo signed legislation that permitted the practice on projects state-wide. His immediate goal in doing so was to provide a channel to help fast-track the then-proposed replacement of the Tappan Zee Bridge north of town, the first design-build contract in the State’s history, but that’s another story for another time…

2018 Mojave Road Trip Part 2; The deadly desert highway (California State Route 127 and Nevada State Route 373)

After leaving Barstow via Old Highway 58 my next destination was in Death Valley.  To access Death Valley from rural San Bernardino County required a trek on north on Interstate 15 to California State Route 127 which becomes Nevada State Route 373 at the state line. Along I-15 I encountered the road sign oddity that is Zzyzx Road about eight miles south of Baker.   Zzyzx Road is a four mile road that used to go to the Zzyzx Mineral Springs and Health Spa.   The spa was founded in the 1940s and the owner made up the name "Zzyzx" to claim it was the last word in the English Language.  The spa has been shut down since the 1970s and is now part of a Desert Studies Center for California State University. The southern terminus of CA 127 in Baker is located at I-15 exit 246.  CA 127 is a 91 mile north/south highway which runs to the Nevada State Line in Inyo County.  CA 127 is called Death Valley Road from I-15 northward.  South of CA 127 ...

Finding the Pre-Emption Road of New York State

  The Pre-Emption Road (or rather a series of roads named Pre-Emption Road) follows a survey line called the Pre-Emption Line, drawn in the early days of the United States. The story begins with Massachusetts and New York having competing land claims to modern day Western New York State that have their roots in colonial charters granted by the British. After the Revolutionary War ended, this land became the frontier of the nation and its settlement became a priority for the new American government. During this era, there were a lot of competing land claims that needed to be settled. It was no different with the land claims between New York State and Massachusetts. On November 30, 1786, Massachusetts and New York sent representatives to Hartford, Connecticut to resolve their competing land claims. In less than three weeks, the representatives had reached a compromise. Massachusetts would receive pre-emption rights, meaning the right to sell the land after the Indian title ...

What's In a Name?: When the Roads Really Do Tell a Story

  Our tagline on the Gribblenation blog is "because every road tells a story". Some roads tell different stories than others. Along our travels, we may see historic markers that tell us a little story about the roads we travel or the places we pass by. Some historic markers are more general, as to telling us who lived where or what old trail traversed between two towns. During my travels across New York State and other states or provinces, I pass by many historic markers, some with interesting or amusing references to roads. I wanted to highlight a few of the markers I've seen along my travels around the Empire State and help tell their stories. Those stories may be as specific as explaining the tales of a tree that was used to help measure a distance of eight miles from Bath to Avoca in Steuben County, as referenced on the Eight Mile Tree historical marker above. They may also help point the way along historical roads first used centuries ago, or may help tell a local l...
