The leaders responsible for running the Mackinac Bridge say there are no direct threats to the bridge, but they are in the process of identifying and fixing weaknesses to bridge security to make sure nothing happens.
After terror attacks around the world involving radical Islamic extremists using cars to murder people on places like the London Bridge, Mackinac Bridge authorities say they made the right call shutting the bridge down on Labor Day this year.
According to reports:
"Just a few weeks ago, in the wake of several similar incidents of cars running into groups of people, the bridge authority board decided to close the bridge from 6:30 a.m. until Noon on Labor Day.
They say there are no threats to the bridge or Michigan, but it's better to err on the side of caution.
“It's these emerging threats throughout the world and even in the U.S. is why we decided that we have vulnerabilities out here on the bridge that we want to take care of,” said Bob Sweeney of the Mackinac Bridge Authority."
