The Carleton Laboratory, under the leadership of Civil Engineering faculty members Prof. Rene Testa and Prof. Andrew Smyth, recently completed a vibrations investigation of the Manhattan Bridge. The project, supported both logistically and technologically by Carleton Lab, allows the New York City Department of Transportation to ensure that the Manhattan Bridge remains a safe thoroughfare between Brooklyn and New York for the coming decades.
The instrumentation of the Manhattan Bridge took on an adventurous note when the deployment schedules required the instrumentation of both the bridge towers and cables.
