Resensys Installs Tilt and Water Level SenSpot Sensors on Trancas Creek Bridge in Malibu, CA

On November 14th and 15th, 2017, Resensys installed 6 SenSpot Wireless Inclinometers, SenSpot Water Level sensor and 2 SeniMax data loggers on Trancas Creek Bridge in Malibu, CA. Trancas Creek Bridge is a coastal, 100 foot bridge that spans Trancas Creek, and carries an average of 22,100 vehicles per day. The bridge was built in 1927, and renovated in 1938.

California transportation authorities have long been aware that Trancas Creek Bridge is at risk of scouring – a process whereby fast-moving currents erode the sediment near the base of the bridge’s supports. In 1967, the bridge’s east abundments were washed out due to a scouring-related issue. Thus, California sought a way to make the Trancas Creek Bridge safer, and monitor the incline of the bridge to insure against new scouring threats against the bridge’s structural integrity.

Resensys’ wireless tilt SenSpots were installed on both of the bridge’s piers, allowing California authorities to constantly monitor the incline of the bridge’s structural components, and detect scour holes before the bridge’s integrity is threatened. Three tilt SenSpots were added to each pier.
