Slider

Project Information

  • Location: Westchester County, New York

  • Client: New York State Department of Transportation

  • Disciplines: Construction Engineering and Inspection

The I-287/Cross Westchester Expressway (CWE), Stage 2 & Stage 3 Reconstruction entailed the extensive rehabilitation of the CWE between Exits 2 and 8, a distance of approximately 6 km. This roadway reconstruction, with a combined construction cost in excess of $275 million for the two (2) stages, was deemed essential to ensure the safety and efficiency of the traveling public along the CWE. This vital transportation artery carries more than 150,000 vehicles on a daily basis.

Stage 2 – The Stage 2 reconstruction between Exits 2 and 5 consisted of: roadway rehabilitation along a 3 km section of the I-287/CWE; adding auxiliary lanes along Exits 3 to 5; five (5) bridge replacements and three (3) bridge rehabilitations; widening ramps, adding turning lanes, a concrete median barrier, drainage structures, noise walls and retaining walls, utility relocation and landscaping.

Stage 3 – The major construction elements of the 2.95 km Stage 3 section included roadway rehabilitation along I-287 CWE between Exits 6 and 8, one (1) new bridge, nine (9) bridge replacements, rehabilitation of another bridge, a precast culvert, relocation of Exit 7, installation of two (2) miles of concrete noise-barrier and retaining walls along both sides of I-287, and the relocation of utilities, including an 800m section of a 40-inch Tennessee Gas Pipeline.

Both Stage 2 & Stage 3 required a complex traffic management plan, staged construction, night operations, and an extremely qualified and knowledgeable Resident Engineer and field staff with extensive experience in the various elements of the project. This expert staff provided their individual and collective expertise to adapt the design to actual field conditions and provided re-designs as necessary. This was a major factor in minimizing contractor disputes, claims, and/or delays.
