What is “ABC”?

Components & Benefits of ABC

Prefabricated Bridge Elements & Systems (PBES) Reduces on site Construction Duration Improves Work Zone & Worker Safety

Minimized Traffic Impacts (Reduced Roadway User Costs)

Primary Objectives

1) Restore the bridge condition using cost effective techniques

2) Minimize life cycle cost of maintenance and repair

Secondary Objectives

3) Utilize construction techniques to minimize traffic impacts to Hooper Road

4) Minimize impacts to NYS Route 17C during construction
