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 exceeding $250 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 (exits 3 to 5); the replacement/rehabilitation of eight bridges (five replacements and three 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 include: 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 experienced in the various elements of the project were required to adapt the design to actual field conditions and to provide re-designs as necessary, thus minimizing contractor disputes, claims, and/or delays.
