The Telegraph Road Bridge (TRB) is a multi-girder composite steel bridge built in 1973 in Monroe, Michigan on Telegraph Road. The bridge is controlled by the Michigan Department of Transportation.[1][2] It has been the subject of a pioneering long term imbedded real time structural monitoring system.
Long-term Structural Monitoring System[edit]
This bridge represents a milestone in the use of electrical structural monitoring of bridges.[2][3][4] It uses a combination of embedded strain gauges, solar panels, and wireless sensing and technology and transmission via the internet and cell phones to compile long term automated daily useful data monitoring the health of this operational bridge. "The work advances the design of a solar-powered wireless sensor network architecture that can be permanently deployed in harsh winter climates where limited solar energy and cold temperatures are normal operational conditions." It monitors "truck load events" and temperature, so that the bridge manager is kept fully informed since it is situated within northern climates of the United States, thereby being subjected to harsh weather and snow and ice removal.[3]
The TRB was selected for one of the first installations of a wireless long-term structural monitoring system for tracking acceleration and strain response of the bridge to environmental and traffic loads. Sensors utilize wireless monitoring system tracking known "deterioration modalities commonly encountered in steel girder-concrete deck bridges." Its integral wireless sensor network uploads raw sensor data so it would be in "Senstore", a scalable database system."[2][5][3] The technology proved successful [4][6][upper-alpha 1]
The bridge utilized "a unique design feature of the bridge is the use of pin and hanger connections to support the bridge main span."[3]
The pilot study is funded by the National Institute of Standards and Technology with support by Michigan Department of Transportation. (MDOT).[15] Testing is part of an infrastructure-monitoring project, scheduled to last five years.[upper-alpha 2]

Notes[edit]
- ↑ Parenthetically, Michigan authorizes the heaviest trucks in the entire country — twice the weight limit. Uniquely, the State of Michigan has a gross vehicle weight limit of 164,000 pounds (74,000 kg), which is twice the U.S. federal limit.[7][8][9] A measure to change the law was defeated in the Michigan Senate in 2019.[10][11][12][13][14]

A dense network of strain gauges, accelerometers and thermometers are installed to acquire bridge responses of interest to the bridge manager including responses that would be affected by long-term bridge deterioration.
