Protecting the Ben Franklin Bridge with Cassette ICCP Technology
Ben Franklin Bridge is one of the most important transportation links in the northeastern United States, carrying thousands of vehicles daily between Pennsylvania and New Jersey. As with many aging reinforced concrete structures, decades of exposure to moisture, chlorides, and environmental contaminants had resulted in corrosion-related deterioration within the bridge's anchorage houses.
To address this ongoing corrosion and preserve the long-term integrity of the structure, an impressed current cathodic protection (ICCP) system was incorporated into the bridge rehabilitation program.
The Challenge
The anchorage houses on both the Pennsylvania and New Jersey sides of the bridge contained reinforced concrete elements exhibiting signs of corrosion-induced deterioration. Left unchecked, corrosion of the embedded reinforcing steel can lead to cracking, delamination, spalling, and increasingly costly repairs over time.
Given the critical nature of the structure, the owner required a long-term corrosion mitigation solution capable of protecting the reinforcing steel while minimizing disruption to the existing structure.
The Solution
The project included the installation of approximately 5,000 meters (16,400 feet) of NoCo's Cassette ICCP system throughout the anchorage houses.
The Cassette system was selected by the project design team because its surface-mounted configuration allows installation directly onto existing concrete substrates, minimizing demolition and invasive construction activities while providing effective long-term corrosion protection.
NoCo supplied the cathodic protection materials in accordance with the corrosion engineer's design, supporting implementation of the ICCP system throughout the rehabilitation project.
Remote Monitoring and Long-Term Protection
The Cassette ICCP system is integrated with the Camur III remote operation and monitoring platform, allowing engineers to continuously monitor system performance from any location. Through cloud-based monitoring, system performance can be reviewed, adjusted, and optimized to ensure compliance with cathodic protection criteria throughout the life of the installation.
This proactive approach allows asset owners to verify system operation, maintain corrosion protection performance, and make informed maintenance decisions without the need for frequent onsite inspections.
Results
- Approximately 5,000 meters (16,400 feet) of Cassette ICCP installed
- Active corrosion mitigation of embedded reinforcing steel
- Minimal invasive work due to surface-mounted anode configuration
- Continuous remote monitoring through the Camur III cloud platform
- Significant extension of service life for critical bridge infrastructure
- Reduced risk of future corrosion-related repairs and associated maintenance costs
Project Impact
By incorporating Cassette ICCP technology into the rehabilitation program, the bridge owner implemented a proactive corrosion management strategy designed to protect critical reinforced concrete components for decades to come. The combination of proven ICCP technology and cloud-based monitoring provides a sustainable, long-term solution for preserving one of the region's most important transportation assets.
