New Jersey Turnpike Interchange 6 E-ZPass Improvements

Gannett Fleming provided final design for express tolling upgrades to the Interchange 6 plaza. Modifying the existing barrier toll plaza added an express E-ZPass lane in each direction to accommodate increased I-95 traffic and improved traffic flow.

The toll booth design required a partial demolition of the existing structure, a new monotube and sign structures, and improved drainage. Our team also provided horizontal and vertical design, transportation engineering and maintenance, and toll plaza and electronic toll collection design.

The team created customized traffic simulation models to inform a complex staging plan that maintained vehicle movement through the facility during construction. Our project staging kept most lanes open during peak hours and additional closures were needed only during off-peak travel times.

Adding additional express E-ZPass lanes to Interchange 6:

• Significantly improves mobility.
• Reduces traffic congestion by allowing vehicles to move safely through the facility.
• Helps maintain highway speeds and minimizes lane changes.
• Improves air quality by reducing the number of queued vehicles idling at traditional toll booths.
• Alleviates traffic bottlenecks that could disrupt evacuations during an emergency.

• New express E-ZPass toll lane in each direction.
• Independent monotube structure for E-ZPass toll collection.
• Full-depth pavement excavation and replacement.
• Construction of five new sign structures.
• Construction of camera installation.
• Roadway re-striping to facilitate efficient traffic flow.

• Enhanced traveler mobility through toll lanes.
• Reduced traffic congestion across regular lanes.
• Decreased vehicle idling time for all occupant vehicles.
