Built in 1901, the Atlantic Avenue Viaduct carries Long Island Rail Road's Atlantic 1 and 2 tracks connecting Jamaica to downtown Brooklyn. This viaduct is located in Brownsville, King County and runs between Nostrand Avenue and Ralph Avenue, with one station located at Nostrand Avenue. The structure is approximately 8,100 feet long and 26 feet wide, with 199 spans varying in length from 30 to 43 feet.

After successfully completing Phase I of this design-build rehabilitation project, Kiewit Constructors Inc. was selected by Long Island Rail Road to perform the design and replacement of an additional 85 spans of the dual-track commuter rail line connecting Jamaica, Queens to downtown Brooklyn. This second phase involved the design of custom spans and the introduction of spiral curves to the correct tunnel alignments at both the east and west ends of the track. Kiewit Constructors Inc. together with their design consultant HNTB worked with LIRR to create a design for span replacements that provided temporary bracing of the structure, repeatable fabrication details, and fall prevention for workers.

Constant communication between all members of the team fostered a spirit of cooperation and enabled the project to be completed with minimal issues. The team included LIRR, Kiewit Constructors Inc., HNTB, the Construction Manager LiRo, LIRR's designer Dewberry, as well as In-House Force Account Track, Traction Power, Signal and Communications personnel. The construction cost was $63 million and the project was completed in December 2010.
