DESIGN BUILD OF ROUTE 6 & ROUTE 10 INTERCHANGE
LOCATION: PROVIDENCE, RI
In December 2017, the 6/10 Constructors Joint Venture (6/10 JV)—a four-company team comprised of Barletta Heavy Division, O&G Industries Inc., D.W. White Construction, and Aetna Bridge Company—was awarded the project. The 6/10 JV had both the highest scoring technical proposal and the lowest bid price with a construction cost estimate of $247 million. It was the largest public works project ever awarded in Rhode Island.
With its size and complexity, the 6/10 Interchange project is noteworthy for several reasons. It entails the design and construction of 12 new bridges: a pair of two-span steel plate girder structures, four single-span steel plate girder structures, four multi-span curved steel plate girder ramp structures, a multi-span twin steel box beam curved flyover ramp structure, and a pedestrian truss bridge spanning Amtrak; 29 retaining walls; 2 miles of roadway reconstruction; 350,000 cu yd of earthwork; 28,000 linear ft of drainage; creative lighting; intelligent transportation systems; and last but not least, landscaping.
