Quiet Concrete and Smart Sensors
For the first time in a project of this scale, mixed-generation concrete – or what’s also known as “quiet concrete” – will cover the surface of the bridge. By using advanced grinding methods, the particles of the concrete mixture reduce the noise of vehicles traveling on pavement, which is particularly important for neighbors living on the shores of sound-reflecting water.
The roadway will also contain traffic data monitoring equipment to get speed and the amount of vehicles traveling on the roadway, along with active traffic management signage. Bridge officials hope to add a high-efficiency street sweeper to help remove debris and contaminants before it goes through the bridge’s stormwater system.
