The county will install asphalt markings that will vibrate and rumble if you cross over them on the Bear Cut Bridge of the Rickenbacker Causeway, a project that will leave only one lane of the bridge open when the work is being done on that side.

The project will be done from 10 a.m. to 3 p.m. Wednesday and Thursday. The eastbound and westbound vehicle lanes closest to the dedicated bicycle lanes of the bridge will be affected. Miami-Dade County Public Works and Waste Management Department (PWWM) will perform the work. Delays are expected.

The markings will alert motorists that they are drifting from the driving lane. When a vehicle goes over them, they cause a vibration and an audible rumble that is transmitted through the vehicle’s wheels into the vehicle interior. The county says the markings should reduce run-off-the-road collisions, especially important since the lanes are next to bicycle and pedestrian paths.

Several cyclists have been hit by cars and killed over the years while riding on the Rickenbacker Causeway. In February 2012, Aaron Cohen was killed by Michele Traverso while cycling on the causeway. The Florida Legislature subsequently passed the Aaron Cohen Life Protection Act, signed into law last year, which imposes a mandatory prison sentence of four years for drivers convicted of leaving the scene of a crash that kills someone. Traverso had left the scene.
