    In October 2013, temporary navigational lights were relocated as per the diagram below at the existing Tappan Zee Bridge across the Hudson River at mile 27.0. The new temporary navigational lighting plan includes marking the 600 foot wide main channel by affixing four-180° steady, red navigation lights to the underside of the main span, 2 each on the upstream and downstream sides of the structure, 300 feet either side of the centerline of the bridge. Each green center of channel light has 3 white lights stacked vertically above it. The center 600′ feet of the Main Navigation Channel will be free for the passage of marine traffic and clear of all obstructions at all times.
  • U.S. Army Corps of Engineers Approved Mooring Locations

    The map below is from the January 14, 2014 U.S. Army Corps of Engineers permit modification for the New NY Bridge Project to replace the Tappan Zee. It shows the approved temporary mooring locations for construction barges on the Hudson River during the project. There will be barges moored at these approved locations both day and night during the project and there will be up to 100 barges, crew boats and other vessels in the area at the peak of construction. Originally, there were 4 mooring locations established in the spring of 2013. 12 additional areas have been approved and the initial 4 will also be reconfigured. The U.S. Coast Guard has issued the following guidance in its Notice to Mariners: “When transiting the area mariners should stay clear of these locations by a minimum of 1000 feet. Mariners are advised to transit the main channel, reduce wake and use extreme caution while transiting the area in the vicinity of the Tappan Zee Bridge paying particular attention to vessel movement and future notices.

Redactions under the Freedom of Information Law

Please be advised that certain records have been redacted or withheld in accordance with the following subsections of New York State’s Public Officers Law §87(2):

Portions of the records have been redacted or withheld in their entirety under section 87(2)(a) as the information is specifically exempted from disclosure by state or federal statute. [Including, but not limited, to 49 USC §40119 and by extension 49 CFR, Part 15.

Request For Proposals (RFP)

On March 9, 2012 the Final Request for Proposals (RFP) was made available to the four firms on the short list who are eligible to submit proposals to design and build the new Tappan Zee Bridge.

To continue to promote an open and transparent procurement process, this RFP document is being provided for informational purposes only. No public comments relating to the RFP are being solicited or responded to. The Public Comment period is closed.

Section 1503 of SAFETEA-LU (August 10, 2005) revised design-build regulations to provide for increased flexibility in initiating the design-build procurement process as it relates to the completion of the environmental review process. This flexibility has been consistent with the Administration’s Every Day Counts Initiative, which encourages conducting project delivery concurrently to the extent allowable. It allowed State transportation departments to issue request for proposals and preliminary design work under design-build contracts prior to the completion of the NEPA process. This revision also allows states to realize sooner the advantages of time and cost savings and improved quality for projects that use design-build procurement. Since the RFP has been issued prior to the conclusion of the NEPA process, the document informs the proposers that no commitment will be made to any alternative under evaluation in the NEPA process, including the no-build alternative. The document includes appropriate provisions ensuring that all environmental and mitigation measures identified in the NEPA document will be implemented.

Request For Qualifications (RFQ)

The New York State Department of Transportation (NYSDOT) and the New York State Thruway Authority (NYSTA) – collectively, the Agencies – have issued a Request for Qualifications (RFQ) for firms interested in participating in the design and construction of a new bridge across the Hudson River near Tarrytown, New York. The RFQ documentation can be accessed at the link(s) below. The RFQ sets out the pre-qualification process for firms seeking to be short-listed as project Proposers, and it provides details of the Statement of Qualifications (SOQs) required from interested firms. The deadline for submitting SOQs was January 10, 2012.

On January 10, 2012, Statements of Qualification were received from world class design-build teams. After evaluation, a shortlist of the most highly qualified teams has been announced. The teams listed on the shortlist below will be invited to respond to a Request for Proposals.

Scope Summary Report

This Scoping Summary Report incorporates information provided in the Scoping Information Packet for the Tappan Zee Hudson River Crossing Project, lists public and agency comments on the Scoping Information Packet, responds to the comments received, and includes updated information as necessary to address the public comments. Updated or revised text is shown in italics throughout this document. This document describes the purpose and need for the project (Section 1); the alternatives under consideration (Section 2); the framework for the project’s environmental analysis (Section 3); the public involvement program for the project (Section 4), and agency and public comments and responses (Section 5).

The purpose of the project is to maintain a vital link in the regional and national transportation network by providing a Hudson River crossing between Rockland and Westchester Counties, New York that addresses the limitations and shortcomings of the existing Governor Malcolm Wilson Tappan Zee Bridge (“Tappan Zee Bridge”). The project would address the structural, operational, safety, security and mobility needs of the Tappan Zee Hudson River Crossing.
