Long Island Sound link
The Long Island Sound link is a proposed bridge or tunnel that would link Long Island to the south with New York or Connecticut to the north across the Long Island Sound. The most recent proposal involves a tunnel between Rye, New York, on the mainland and Oyster Bay on the island. Feasibility studies for both bridges and tunnels have been conducted for numerous entry points, as listed in the chart below.
Long Island is connected via tunnels and bridges to Staten Island, Manhattan, and the Bronx. People who wish to travel from Long Island to New York's mainland or New England via automobile have no better option than to cross the Throgs Neck Bridge or the Bronx–Whitestone Bridge, which are located on the northwestern corner of Long Island. Ferry service between Connecticut and Long Island is available year round; the drawback is that it is a slow-moving vessel, and it therefore takes enough time to cross the Long Island Sound that, if a traveler is going some place in western Connecticut, it may be more time-effective to drive rather than use the ferry, even from points farther east than Port Jefferson, the very town from which the ferry originates. Private companies operate automobile ferries between Bridgeport, Connecticut, and Port Jefferson on central Long Island, and between New London, Connecticut, and Orient Point on eastern Long Island.
A bridge or tunnel to the center of the island would make most of the island more accessible, and would reduce the travel time of certain routes by hours. However, the cost of a bridge would be large and it would be likely to have adverse environmental impacts. If built, a span across the widest portion of the Sound between New Haven and Shoreham would be approximately 22 to 25 miles (35 to 40 km) in length, possibly making it one of the longest bridges in the world.
A variety of bridge routes have been proposed:
- A bridge connecting Mamaroneck in Westchester County, New York, with Sands Point on Long Island. This bridge would lead to a possible spur of the Bronx-White Plains Expressway onto Long Island via the unbuilt Western Nassau Expressway in Nassau County.
- A bridge connecting Rye in Westchester County with Oyster Bay on Long Island. This bridge would be an extension of Interstate 287 onto Long Island via the existing Seaford-Oyster Bay Expressway in Nassau County.
- A second bridge connecting Rye to the city of Glen Cove on Long Island. This bridge would have connected to the Glen Cove Arterial Highway on Long Island.
- A bridge connecting Asharoken, New York, to either Stamford or Norwalk, Connecticut. This bridge would have connected to the unbuilt Babylon-Northport Expressway in western Suffolk County. In Norwalk, it would have led to the already upgraded U.S. Route 7, while in Stamford, it would more than likely have connected to the unbuilt Pound Ridge-Stamford Expressway, and lead back into New York.
- A bridge and possible dam connecting Poquott, New York, to Bridgeport, Connecticut. This bridge would have connected the unbuilt Suffolk County Road 110 (A.O. Smith Turnpike) to CT 8/25.
- A bridge connecting either New Haven or East Haven, Connecticut, with Shoreham, New York, on Long Island. This bridge would be an extension of Interstate 91 which would continue through Long Island via the already existing William Floyd Parkway.
- A bridge connecting Riverhead, New York, with Guilford, Connecticut. This bridge would have connected at an alternate extension of Interstate 495 to Exit 59 on the Connecticut Turnpike.
- A bridge connecting Old Saybrook, Connecticut, with East Marion, New York. This bridge would have connected the east end of the Long Island Expressway with CT 9 near Interstate 95 in Connecticut.
- A causeway and bridge connecting Orient, New York, with Rhode Island along a series of islands between the North Fork of Long Island and an eastern terminus at Interstate 95 in Rhode Island.
All nine ideas were discussed in the 1950s, 1960s, and 1970s, but all were canceled. Some were reconsidered during the 1990s, but the New York State Department of Transportation backed away from the idea in belief that it would not relieve congestion. Long Islanders seem to favor a bridge, but New Englanders are not very supportive of the idea, claiming that it would benefit Long Island at their expense.
In 1957, a plan for a bridge to Westchester County across the Long Island Sound was first proposed by Charles H. Sells, a former commissioner for the New York State Department of Public Works. His proposal for the Oyster Bay – Rye Bridge, along with the eastern Orient Point – Watch Hill Bridge, were two proposed bridge routes off Long Island. Sells, however, suggested that the bridges would not be constructed until Long Island's traffic and commuting began to increase.
In seven years, Long Island underwent the transformation that Sells had expected, and the east–west arterials between Long Island and New York City, such as the Northern State Parkway and the Long Island Expressway, were congested with commuters. Motorists bound for New England or upstate regions of New York had to take the Throgs Neck Bridge or the Bronx–Whitestone Bridge, both bridges already reaching their designed capacities. Robert Moses, chairman of the Triborough Bridge and Tunnel Authority, worked with the Department of Public Works to commission a $150,000 study in 1964 by the firm Madigan-Hyland to study the feasibility of a bridge across the sound.
Moses revealed the results of the study to the Nassau and Suffolk Regional Planning Board in February 1966. The Oyster Bay – Rye Bridge (originally the Bayville – Rye Bridge) was proposed to complete the Interstate 287 beltway around the New York Metropolitan Area. This was to be done by constructing a 6.1-mile-long (9.8 km) cable-stayed suspension bridge bridge from the Cross Westchester Expressway (I-287) in Rye to the Seaford – Oyster Bay Expressway (NY 135) in Nassau County. The proposed bridge was to cost $150 million (1966 USD) and had the support of Governor Nelson Rockefeller and many officials on Long Island.
On March 1, 1968, the Triborough Bridge and Tunnel Authority merged with the Metropolitan Transportation Authority (MTA), and Moses was demoted from chairman and given a lower position only because he would have a leading role in construction of the bridge. Also, a number of excuses for delaying construction of the bridge were coming from the governor's offices. In 1969, the office said that the bond market, which would help finance the bridge, was too soft. The next year, there was a gubernatorial election for Rockefeller, and with the affected communities up in arms against him, he did not want to be put on the spot while running for re-election as governor.
In 1971, the excuse was that financial problems resurfaced on the proposed bridge and delayed it yet another year. The following year, the campaign for the Republican-controlled legislature in New York and governor were yet another reason to delay construction. With each delay out of the governor's office, Moses kept assuring that the bridge would begin construction the next year.
However, in that time frame of excuses, Governor Rockefeller ordered a halt to the heated issue in 1970 to conduct another feasibility study, costing about $160,000. That same year, new federal laws that dealt with the environment meant that another study had to be conducted for the highway, this time for the approaches as well.
With the mainline construction of the Seaford – Oyster Bay Expressway completed, Moses turned his eyes back onto an extension of the freeway and onto a bridge across the Long Island Sound into Westchester County (in the city of Rye). The idea, produced by Moses, was to extend the freeway northward past its current terminus, and along its previously proposed right-of-way past NY 106. Based on the Nassau County Department of Public Works Master Plan of 1959, the expressway would follow West Shore Road and Lundlum Avenue through Oyster Bay to Bayville, where it would connect to the new crossing.
In November 1972, Moses, the recently created New York State Department of Transportation (NYSDOT), and the MTA submitted the environmental impact statement (EIS) for the bridge. The statement specified that the project was to include the approaches to the bridge (I-287 and NY 135) and be a 16.5-mile (26.6 km) project, as that was the distance from the interchange of I-287 and I-95 in Rye to the interchange of NY 135 and NY 25 in Syosset. The statement also explained how the highway would become an extended part of I-287. The bridge was to be constructed with four lanes, about 135 feet (41 m) above the sound at maximum clearances and 55 feet (17 m) on the minimum clearances. There would be 1,200 feet (370 m) of a center between the two towers along the cable span. These minimums reported by the two authorities and Moses were equal to those of the bridges crossing the East River in New York City. The main span would have a median divider separating the directional lanes, along with a girder box to allow for smooth passing.
In Westchester County, there were four proposed alternatives to the approach of the bridge. The first three proposals, designated W-1, W-2, and W-3, would use the undeveloped area around Playland Park in Rye for the approach. Proposals W-1 and W-2 would use Kirby Lane and Forest Avenue and be on a low-viaduct structure. Proposal W-3 would follow a narrow piece of land between Kirby Pond and the water between Mansuring Island. W-4 was to go through Port Chester Harbor and head across the Sound near North Mansuring Island. The approaches were to have retaining walls, side slopes, and screening which were to help blend in with the area and reduce the amount of properties seized.
Across the Sound in Nassau County, three alternatives were considered for the bridge approach. The first, designated N-1, went from Oak Neck Point southward to an underpass of Bayville Avenue and into a deep cut of about 40 feet (12 m) near Mill Neck Creek. The cuts were to be built so they would be hidden from local properties. From there it would follow West Shore Road into Oyster Bay and utilize NY 106 to get onto the expressway extension. The second alternative, designated N-2, utilized most of N-1's route except for a cut through Mill Neck and onto a viaduct about 2,000 feet (610 m) long with varying clearances. After Mill Neck, it would follow the alignment of proposal N-1. N-3 was significantly different from the other two proposed and would use a longer bridge over the Sound, touching down in Ferry Beach rather than Bayville. The route would then pass to the east of the business district in Bayville and cross over the Mill Neck Creek on a viaduct with a 30 feet (9.1 m) clearance. Alternatives N-1 and N-2 were a bit more than 4 miles (6 km) long, and alternative N-3 was a little more than 3 miles (5 km) long.
On the Nassau side, full cloverleaf interchanges would have been built at NY 106 and NY 25A (North Hempstead Turnpike), and ramps to and from Bayville Avenue were proposed to be used for southbound traffic. This would allow local residents to use the approach route but not have to use local roads in the process. The total costs for the entire project were $200 million for the bridge itself and $52–72 million on the approaches, depending on which route was selected. Another $25 million would have gone toward the completion of NY 135 between NY 25 (the Jericho Turnpike) and NY 106.
It was believed that the bridge would have positive effects on both traffic and the local economy, as I-95 (the New England Thruway) would lose some of its congestion as traffic would be diverted onto the new bridge from Long Island rather than through New York City and on the East River bridges. This would also help the traffic flow from I-95 onto the Cross Westchester and raise the amount of turning movements in the area. Similarly, the Hutchinson River Parkway would benefit from the diversion of traffic onto the bridge. The economic effects would be substantial, with a projected 11.8 million people using the bridge in the first year alone. By the fifth year, the proposed traffic volume was 16 million, and by its twentieth year in existence, 23 million people would use the bridge. The tolls, $1.75 for passenger cars and a significantly higher toll for commercial vehicles, would lead to a $21.5 million increase in revenue in the first year and an increase of $43 million by the twentieth year.
Other than monetary benefits, there were also to be economic benefits:
A wider regional market will be available to business enterprises on both sides of the Sound, thereby creating more favorable conditions for establishment of new businesses and expansion of older ones. This applies particularly to specialized enterprises serving areas broader than individual localities.
Employment opportunities will be broader for residents on both sides of the Sound. Individuals with special skills will have a wider field in which to locate, and there will be more opportunity to match skills with jobs. As a result, income levels will often rise as people will be more able to utilize their maximum abilities. The need to relocate families in order to gain better access to employment will be diminished.
Because the bridge will contribute to a healthy economic development of the region, it will have a favorable general effect on property values and therefore on the tax base. Consequently, it will tend to hold down tax rates. These favorable impacts may have been the experience of many transportation improvements.
Movement of goods will be an important function of the new bridge. For the first time, highway access will be available for freight movements to and from Long Island without the need to overcome New York City congestion. Freight shipments to Long Island are now charged at a premium rate. Construction of the bridge could result in a reduction in rates for Long Island shippers and receivers, with a possible favorable effect on the cost of living as well as on the costs of doing business.Construction of a major project of the magnitude of the proposed bridge and its approach highways will provide a substantial number of jobs during the period it is under construction. Approximately 55 percent of the total cost of construction will be for labor, of which the major element will be on-site. It is estimated that approximately 6,400 man-hours of work will be required, spaced over a three-year period. This means an average of about 2,100 men working on the project, with a peak force of perhaps 3,000 workers. In addition to the labor employed directly on contract work, both on-site and off-site, there will also be employment created in the furnishing of materials, supplies and services required for the project. Secondary economic benefits also will be realized from expenditures by workers employed on the project, both in the vicinity of the bridge site and elsewhere in the region. All of this economic activity will produce substantial additional income for the region, most of it without requiring additional permanent community services.—Robert Moses, NYSDOT and MTA, Oyster Bay – Rye Bridge Economic Impact Statement (1973)
However, Moses ran into a problem once the proposal was brought to the Federal Highway Administration. Opposition to the bridge was beginning to form on both sides of the Long Island Sound. In addition, plans to turn the Oyster Bay area into a bird sanctuary and a protected park made working on the highway harder, as building on such protected places is forbidden by law. Faced with growing opposition, Governor Rockefeller canceled the plans for the bridge on June 20, 1973, nine years after the first proposal by Moses.
In January 2008, this idea re-entered public discussion when developer Vincent Polimeni proposed building a privately financed, tolled tunnel between Oyster Bay on Long Island and Rye in Westchester County, featuring two tubes carrying three lanes of traffic each and a third tube for maintenance and emergency access. The route would connect Route 135 (Seaford-Oyster Bay Expressway) on Long Island to Interstate 287 in Westchester County. It would cost $10 billion and would not be completed until at least 2025. The proposed tunnel would be 16 to 18 miles (26 to 29 km) long, making it the world's longest highway tunnel, longer than the Lærdal Tunnel in Norway. A hearing on this proposal was held in Syosset on January 24, 2008.
