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.

Intersection Conflict Points

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

$2,000 to $4,000/light pole

(generally half the cost)

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.

What’s Next?

• PennDOT and the City of Warren are evaluating the two alternatives for the intersection of (SR 6006) Pennsylvania Avenue, (SR 1017) Market Street, and Water Street.

– Signal Replacement and Retiming with Geometric Improvements

– Single Lane Roundabout

• PennDOT and City officials will take public feedback into consideration.
