VERRAZANO-NARROWS BRIDGE MASTER PLAN

INT NTRODUCTIO RODUCTION

  • The Verrazano-Narrows Bridge (VNB) is an

iconic, irreplaceable 50-year-old structure and a critical transportation link in the I-278 corridor (Staten Island Expressway/Gowanus Expressway).

  • Many of the Upper Level approach structures

and Belt Parkway ramps are the original construction from 1964.

  • Since 1992 Triborough Bridge and Tunnel

Authority (TBTA) has invested $927 Million in capital improvements.

  • More than $1.5 Billion will be invested over

the next 25 years.

  • Reconstructing the Upper Level Approaches,

Lower Level Suspended Span deck, and the connecting ramps and roadways are the next major elements in the long-term plan to reconstruct the VNB.

  • These reconstruction projects are

required to maintain the facility in a state of good repair and to improve access, safety and meet modern design standards.

  • While planning these necessary

upgrades, TBTA is also assessing the feasibility of possibly providing pedestrian and bicycle access across the bridge.

  • In 2014 TBTA started this Master

Plan Study to assess the best way to address the VNB’s long-term

  • needs. This presentation reflects

progress to date.

GOALS AND OBJECTIVES

  • Extend the lifespan and enhance the functionality of the

Bridge and its approaches

  • Improve traffic safety and operations for customers and

Authority personnel

  • Minimize adverse impacts on customers, environment and

neighboring community

  • Optimize capital and operating investments
  • Optimize sequence of project implementation

  • First reconstruction of the LL suspended span

deck since it opened for traffic in 1969

  • Replacing concrete deck with a lighter deck will

decrease the weight of the Bridge

  • Wind and seismic improvements
  • Challenging construction staging due to

constraints with center median and columns

  • Reconstructing Brooklyn approach ramps

provides greater operational flexibility and minimizes traffic impacts when replacing the deck Because much advance planning and study are required, TBTA is starting preliminary design in the 2015-2019 Capital Program.

OPP PPOR ORTUNI TUNITY Y FOR R SH SHAR ARED-USE USE ACCESS SS

  • The Lower Level Suspended Deck Replacement project creates

the opportunity to lighten bridge and possibly accommodate a shared-use path

  • Approximately 12,000 tons need to be removed to

accommodate paths on both sides of the bridge

  • Similar to Upper Level Deck Replacement which lightened

bridge to accommodate a Bus/HOV lane

SH SHAR ARED-US USE E ACCESS SS STU TUDY

  • The VNB was not originally designed for bicycle/pedestrian

access

  • Retrofitting a long-span suspension bridge to accommodate

a shared use path is rare

  • Modifications must not:

– diminish bridge safety and structural integrity – increase the weight of the bridge – reduce traffic capacity

  • Requires significant engineering and testing of wind effects
