This year, ACEC New York has recognized two high-profile transportation projects—one in New York and one in Connecticut. The Gowanus Expressway (I-278) in Brooklyn, New York, is a critical component of New York City’s highway system, connecting the Verrazano-Narrows Bridge to the Hugh L. Carey Tunnel, a distance of approximately six miles. The approximately 200,000 vehicles that utilize the Gowanus Expressway each day will undoubtedly benefit from the New York State Department of Transportation’s (NYSDOT) extensive improvements to this transportation corridor.
I-95 between Interchange 14 and 15 in Norwalk, Connecticut, had been referred to as “the worst highway choke point on the I-95 corridor” prior to recent upgrades by the Connecticut Department of Transportation (ConnDOT).
Gowanus Expressway Emergency Repair, Brooklyn—Diamond Award
The steel structure and roadway surface had deteriorated over the years, and the NYSDOT’s $214 million rehabilitation project provided for the replacement of the deck from the Shore Parkway Interchange to 6th Avenue.
Major elements of the project included the construction of a new 16-foot-wide, 2,300-foot-long slip ramp (flyover) in the Gowanus median between 58th Street and 4th Avenue to carry the HOV lane, the viaduct’s deck replacement, from 6th Avenue to 51st Street, steel repairs of the superstructure and widening of the at-grade Gowanus from 92nd Street to 6th Avenue.
The newly constructed flyover ramp played a significant role in facilitating the deck replacement while minimizing impacts to traffic. The project is also enabling NYSDOT to create a continuous 12.5-mile bus/HOV lane during AM rush hours from Victory Boulevard on Staten Island to the Hugh L. Carey Tunnel, which will be fully operational once the New York City Metropolitan Transportation Authority completes its bus/HOV lane on the Verrazano-Narrows Bridge. This extensive bus/HOV lane is a major benefit in the critical I-278 transportation corridor that is heavily used by commuters and commercial traffic.
HAKS, in joint venture, served as construction inspector and performed field testing.
I-95 Interchange 14 and 15/Route 1 Improvements—Platinum Award
ConnDOT initiated this $43 million project to alleviate the heavy congestion in this area during peak hours and increase storage on the ramps. The solution was the construction of continuous auxiliary lanes (speed change lanes) between Interchange 14 (Route 1) and Interchange 15 (Route 7) and improvements to Route 1 in Norwalk. Infrastructure improvements also included the reconstruction of three overpass bridges (Fairfield Avenue, Cedar Street and Taylor Avenue) to span the new highway width and offer higher clearances. In addition, improvements and new elements to the drainage system were installed to improve stormwater treatment and reduce flooding in the area. Improvements to Route 1 included widening and dedicated turn lanes at the four intersections, an upgraded storm drainage system and other improvements for pedestrian and traffic operations, including the addition of 7-foot-wide sidewalks.
HAKS provided resident engineering and construction inspection.
HAKS will be a Gold Sponsor of the awards ceremony on March 19 at the Waldorf Astoria.
