SR 6006 (Pennsylvania Avenue), SR 1017 (Market Street), and Water Street Intersection Improvement
City of Warren, Warren County, PA
Project Goals
• Safety Improvements
– Reduce crashes
– The intersection has a history of vehicles hitting fixed objects.
• Drainage Improvements
– Update inlets and pipes to current standards.
• Arterial Efficiency and Operations
– Signalized intersections within the city are not currently interconnected.
– Improve traffic flow in the system.

Lighting/Signal Pole Options
Standard Poles (Galvanized)
– No additional cost to City
Standard Poles Painted Black
– No additional cost to City
Decorative Poles Painted Black
– City responsible for:
$12,000 to $16,000/signal pole

Project Goals Satisfied?
• Safety Improvements
– Statistically, roundabouts are safer than traditional signalized intersections.
– Both alternatives will improve the geometry of the intersection and accommodate large vehicles.
• Drainage Improvements
– The existing drainage network will be improved with either alternative; however, the roundabout would require a more complex drainage system.
• Arterial Efficiency and Operations
– Both alternatives would improve the efficiency and operation of the arterial network.
