The Challenge

Engineers needed a fast, simple and cost-effective way of determining the safety of the Lake Champlain Bridge. If a replacement was needed, the safety of workers and civilians needed to be guaranteed throughout the process.

The Customer
Lake Champlain Bridge
About The Customer
Originally constructed in the 1920s, the Lake Champlain Bridge was the only rail bridge connecting New York and Vermont within 100 miles. But after 80 years of operation, engineers had a sneaking suspicion deterioration was taking its toll.
The Solution

HNTB, an architecture, engineering, planning and construction firm relied on the CX1 structural response monitor to track temperature, wind and pier movement, as well as sustained environmental and manmade elements. The versatile, all-in-one device continuously mounted on the pier caps so engineers could monitor tilt data to identify any sudden movements or change in stability. The CX1 also measured acceleration data to capture any indications of potential fractures within the concrete piers.

Data Collected
Device Diagnostic Status, Fault Detection, Infrastructure Condition, Temperature, Wind Direction
Operational Impact
  • [Efficiency Improvement - Maintenance]
    Real-time status reports enable maintenance personnel to remotely diagnose the status of a device.
  • [Process Optimization - Real Time Asset Tracking]
    The location of individuals and assets can be identified in near real-time.
Quantitative Benefit
  • Within just the first week of operation, SENSR technology identified deterioration and frozen bearings that were delivering forces to bridge piers.
