Bridge Importance
Hooper Road – Urban Arterial
Large Traffic Volumes – ADT 10,000
Vital Link between Residential & Commercial Areas
Previous Construction Projects & Traffic Disruption

Detour West
3 miles – Route 17C North Street, Hayes Avenue
Watson Boulevard Detour East
6 miles – Rt 17C Rt 17, Rt 201, Harry L Drive
Watson Boulevard
Hooper Road Detour
1. Conventional Construction
2. Accelerated Bridge Construction (ABC)
Options for Construction
• Bridge Constructed in Halves
• One Lane of Traffic on Hooper Road during Construction
• Hooper Road Southbound Maintained on Bridge
• Hooper Road Northbound – Off Site Detour
• Traffic Impact to Hooper Road = 4-5 Months
• Bridge Closed to Traffic During Construction
• Bridge Constructed with Prefabricated Elements to Accelerate Construction
• Hooper Road NB & SB – Off Site Detour
• Traffic Impact to Hooper Road = Approx. 2-4 Weeks
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
