| | Atlantic Avenue Viaduct
Brooklyn, NY
Dewberry provided preliminary design and development of design-build documents for this $150-200-million rehabilitation of the 8,000-foot-long, 199-span Atlantic Avenue Viadict for the MTA-Long Island Railroad (LIRR). The 100-year-old structure carries a large number of trains traveling to and from LIRR storage facilities. Dewberry's team has special expertise in evaluating steel structure fatigue and a solid understanding of how to build major line structures in New York City using design-build delivery. Under a separate contract, Dewberry is providing construction phase support services to LIRR. |

| | Trenton Station Renovation
Trenton, NJ
Dewberry's design of a new intermodal transportation center transformed the previous 30-year-old commuter rail station. Final design included expansion of the building's footprint and addition of a second floor/mezzanine level. Exterior work included improved traffic and vehicular circulation, a kiss-and-ride drop-off, site drainage and utilities, parking lot design, and landscaping. Dewberry also provided structural designs for a police substation and additional office and retail space. Temporary shielding bridges and a pedestrian access bridge minimized impact to commuters and expedited construction. |
