ENB Region 2 Completed Applications 05/25/2005

    Applicant is seeking authorization to reconstruct the Fresh Creek Basin Bridge in Brooklyn, New York, which carries the Shore Parkway over Fresh Creek Basin. Both the superstructures and the substructures of the existing bridge will be completely demolished and reconstructed in place. The bridge deck and the approaches will will be widened to 120 feet, from the existing 96 feet to accommodate three 12-foot lanes in each direction, 12 foot wide shoulders and a 12 foot wide bike path.

    During construction the Applicant proposes to maintain three lanes of traffic in each direction at all times. This is possible without the use of temporary structures by the widened new deck. All traffic during construction will be carried by portions of either the existing bridge or the partially completed new bridge. The eastbound bike path will also be maintained during construction.

    The proposed project includes the removal of approximately 2,200 cubic yards of sediments for placement of the new cofferdams and placement of approximately 1,125 cubic yards of clean fill below the spring high water line. The Applicant is presently in discussions with the Department regarding plans for mitigation of wetland impacts.

Mill Basin Bridge is a bascule (moveable)bridge located on the Belt Parkway about one mile east of the Flatbush Avenue exit in the Borough of Brooklyn, NY. The bridge carries the parkway over Mill Basin, a navigable waterway.

New York City Department of Transportation (the Applicant) proposes to replace the existing bascule bridge with a new 11-span high-level fixed bridge. In addition to the new bridge the Mill Basin bridge replacement project includes two new permanent retaining walls on the approaches , new approach roadway embankments, a new fender protective system for the main channel piers, and the removal of the existing bridge and fender system.The new bridge and the centerline of the parkway would be relocated approximately 144 feet north of the existing alignment. The new bridge will consist of a precast, prestressed concrete girder-supported reinforced concrete deck slab superstructure, supported by reinforced concrete column piers founded on precast, prestressed concrete piles. The new bridge will carry three travel lanes in each direction and a pedestrian/ bicycle pathway. The existing bridge will be removed upon the completion of the new bridge. The navigational channel will remain open throughout the construction of the new bridge and demolition of the old bridge.

The Applicant expects to  maintain three lanes of traffic in each direction and the bicycle/pedestrian path throughout the construction period.

Mitigation is required for westland impacts. The Applicant is presently in discussions with the Department to finalize the mitigation plan.

Gerritsen Inlet Bridge is located on the Belt Parkway one mile west of the Flatbush Avenue intersection in the Borough of Brooklyn, NY. The bridge carries the parkway over the Gerritsen Inlet, a navigable waterway.

New York City Department of Transportation proposes to replace the existing 11-span bridge with a continuous 3-span bridge. The new bridge and the centerline of the Belt Parkway would be relocated approximately 36 feet north of the existing alignment.The new bridge's superstructure would consist of continuous steel haunched girders supporting a reinforced concrete deck slab. The superstructure would be supported by reinforced concrete column piers  founded on pre-cast, prestresses concrete cylindrical piles. The construction of the superstructure and substructures in the waterway would employ a construction barge for the driving of concrete piles, the construction of cast in-place concrete piers, and the erection of steel girders. A new fender system will be constructed to protect the new main piers. The fender piles will be driven from a construction barge. The navigation channel will remain open during construction.Upon completion of the new bridge the existing bridge would be demolished. All of the demolition work is anticipated to be conducted from construction barges anchored in the water.

Construction of the new bridge and approach roadways will be performed in four stages while maintaining three lanes of traffic in each direction and the bicycle/pedestrian path. The total duration of the construction period is 42 months, with the construction barges being used for 27 months and in-water work taking approximately 13 months.

Mitigation is required for westland impacts. The Applicant is presently in discussions with the Department to finalize the mitigation plan.

The Paerdegat Basin bridge is located on the Belt Parkway approximately 0.82 miles west of the Rockaway Parkway intersection in the Borough of Brooklyn, NY. The bridge carries the parkway over Paerdegat Basin, a navigable waterway.

New York City Department of Transportation (the Applicant) proposes to replace the existing 13-span bridge with a new split bridge. For westbound traffic a new 3-span bridge would be built on the north side of the existing bridge, and for eastbound traffic a new 5-span bridge would be built on the south side of the existing bridge. The construction of the superstructure and the substructure would would employ a construction barge for the driving of concrete piles , the construction of cast-in-place concrete piers, and the erection of steel girders. The new support piers would be constructed further from the navigation channel, so there will be no adverse impact on the navigation channel. No dredging in the channel is required. Upon completion of the new bridge the existing bridge will be demolished. Much of the demolition work will be conducted from construction barges anchored in the water.

The construction efforts would be divided into four stages while maintaining three lanes of traffic in each direction and continuous passage for bicycles and pedestrians. The total duration of the construction period is anticipated to be 48 months with barges being used for approximately 27 months and in-water work taking 8-10 months.

Mitigation is required for wetlands impacts. The Applicant is presently in discussions with the Department to finalize the mitigation plan.
