ECCO III Enterprises, Inc. was designated by NYSDOT as the best value Design-Builder on the Region 8 Bundled Bridges Project, after receiving a perfect score of 100 on the technical proposal.

The Region 8 Bundled Bridges Project was part of the Scour Critical/Flood Prone Bridge Program, an initiative developed to strengthen New York State’s at-risk bridges to withstand the increasing frequency of severe weather events and storms. The Project aimed to improve the hydraulic opening, reduce scour vulnerability, and reduce the likelihood that the bridges and adjoining roadways would flood.

The project included: the superstructure replacement and abutment and pier rehabilitation for one bridge in Orange County; full bridge replacements for four bridges in Westchester County; and one bridge rehabilitation (pipe-lining) for a bridge in Westchester County.

The largest bridge was the full replacement of the existing bridge that carried the Saw Mill River Parkway over Kisco Avenue in Mount Kisco. This bridge was widened and lengthened, and was founded on rock using both drilled mini-piles and driven piles. The bridge had weathering steel stringers with a cast-in-place concrete deck. Approximately one mile of the Saw Mill River Parkway was milled and resurfaced and the on/off ramps were lengthened to improve site distances for safety.

Many of the bridges were located in high-volume corridors where maintenance and protection of traffic and congestion management were of chief concern. ECCO III’s approach to the Project involved reducing traffic impacts to the greatest extent possible. For example, much of the work in two key sites on the Saw Mill River Parkway was performed at night, re-opening to traffic each morning to avoid delays and detours.
