The I-287/Cross Westchester Expressway (CWE), Stage II & Stage III 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 of the two stages in excess of $275 million, was deemed essential to ensure the safety and efficiency of the traveling public along the CWE. This vital transportation artery carries more than 140,000 vehicles on a daily basis.

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

Stage III – The major construction elements of the 2.95 km Stage III section between Exits 6 and 8 were inclusive of roadway rehabilitation along the CWE between exits 6 and 8, one new bridge, nine bridge replacements, one bridge rehabilitation, and a precast culvert, relocation of Exit 7, installation of two miles of concrete noise-barrier and retaining walls along both sides of I-287, and the relocation of utilities including an 800m section of the Tennessee Gas Pipeline.

Both Stage II & Stage III required a complex traffic management plan, staged construction and night operations. 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.
