The Ohio Department of Transportation is leveraging the latest technology to aid in the inspection and repair of the I-471/Daniel Carter Beard Bridge in Cincinnati, following significant damage from a fire under the bridge’s Ohio approach.

A robotic “dog,” named Brutus, is being used as part of a research project to assist with visual inspections, bridge assessments, and emergency response operations.

Developed by Boston Dynamics, Brutus is part of a collaboration between ODOT and the University of Cincinnati. The project explores Brutus’ potential as a visual observer during drone operations, helping pilots detect and avoid other aircraft. The robot also has broader applications in ODOT operations, including culvert inspections and emergency response efforts.

The robotic dog is equipped with sensors that enable it to conduct a Light Detection and Ranging (LiDAR) scan of the damaged bridge areas. LiDAR technology uses laser pulses to measure distances, creating detailed 3D models that enhance engineers' understanding of structural integrity. The LiDAR data gathered by Brutus supplements drone footage collected after the fire, providing a comprehensive overview of the damage for ODOT engineers.

The fire, which occurred early on November 1, forced the closure of the southbound lanes of I-471 at the Ohio River. The Cincinnati Fire Department found a large fire at a playground in Sawyer Point Park beneath the bridge’s approach span. At the peak of the fire, smoke and flames were visible around and above the interstate. As of now, the fire’s cause remains under investigation by the Cincinnati Fire Department.

In response to the damage, contractors began excavation work on November 7 to install footers that will support shoring towers designed to stabilize the compromised section of I-471. The next steps will involve installing rebar and pouring concrete, followed by a 72-hour curing period before repairs can proceed.
