As the feasibility study of a proposed Oyster Bay (Bayville) to Rye Cross-Sound Bridge is conducted, it might be useful to see the original proposal from 1972.mation booklet published by the MTA and NYSDOT in December 1972 called Long Island Sound Crossing. The booklet was a summary of the findings of the Environmental Impact Statement.
DESCRIPTION OF NASSAU APPROACH: From the shoreline southward, three alternative approach routes are being considered in Nassau County. Alternative N-1 goes from Oak Neck Point southward under Bayville Avenue to a crossing of Mill Neck Creek at its narrowest point. The roadway will generally be in deep cut, as much as 40 feet below the ground surface. It will cross Mill Neck Creek on a 1,100-foot viaduct, providing approximately 60 feet of vertical clearance. Through Mill Neck, the roadways will also be in deep cut and will generally be hidden from nearby properties. The route then parallels West Shore Road into the community of Oyster Bay and connects with the Seaford-Oyster Bay Expressway extension at NY 106. Much of the property for the expressway extension, which is planned to pass through East Norwich and Syosset, has already been purchased.
From a bridgehead slightly to the east of N-1, alternative N-2 passes under Bayville Avenue and crosses Mill Neck Creek on a 2,000-foot viaduct, with vertical clearances varying from 35 to 45 feet. It passes in cut through Mill Neck before joining the N-1 route north of Cleft Road.
Alternative N-3 entails a longer Sound bridge paralleling the shore of Bayville and touching down near Ferry Beach. The route passes to the east of the Bayville business district and then crosses over the entrance to Mill Neck Creek on a viaduct with 30 feet of vertical clearance, just east of the existing Bayville drawbridge.
Interchange locations and configurations will be finally determined through consultation with the communities. It is presently planned to provide ramps at Bayville Avenue to and from the south only. This will permit local residents to use the approach route, but will avoid use of local roads for bridge access. Full (cloverleaf) interchanges are planned at NY 106 and NY 25A (North Hempstead Turnpike).
Approach alternatives N-1 and N-2 are slightly more than four miles in length, while N-3 is a little more than three miles long. The section of the Seaford-Oyster Bay Expressway between NY 106 and NY 25 is about four and one-half miles long.
