Mar 26, 2026 Jim Harkness, chief engineer leading the Francis Scott Key Bridge rebuild, oversees design, structural work, and monitoring plans. He discusses a higher, longer cable-stayed design. Sensors will provide near-real-time structural health data. Towers will include elevators and equipment for maintenance. The new bridge will handle heavier port loads and aims to open in late 2030.

Episode notes
Bridge Will Monitor Its Own Structural Health
- The rebuilt Francis Scott Key Bridge will be higher, longer, and use structural health monitoring to report performance data.
- Jim Harkness says sensors on key elements and 600-foot towers with mechanical access let engineers compare real data to models in near real time.
Onsite View Shows Active Rebuild Operations
- At the construction site, Harkness pointed out tugboats, barges with metal, and multiple cranes supporting the rebuild.
- He described visible activity and said there was more equipment and work on the other side of the site.
Use Sensor Data To Inform Maintenance Decisions
- Use monitoring data to guide maintenance and operations rather than only relying on computational models.
- Harkness emphasizes comparing computed expectations with sensor outputs to spot discrepancies and address concerns early.
