Fake bomb threat causes Detroit Windsor Tunnel closure for 4 hours
By Peter Samuel
The Detroit Windsor Tunnel was closed for about four hours following a fake bomb threat. An employee at the Canadian duty-free store in Windsor reported receiving the threat by telephone at about 12:30 Thursday.
The tunnel was closed to traffic and was searched end to end, but nothing was found. At about 4:30pm the tunnel was reopened.
In the interim traffic was diverted to the nearby Ambassador Bridge where the unusual volumes of traffic caused backups.
The Tunnel of one lane each direction carries about 10,400 vehicles/day average, 3.79m total in 2011. It handles cars mostly (10,130/day), but also buses and a few specially designed compact tractor trailers.
The Ambassador bridge of 2x2 lanes carries an average 19,900 vehicles a day, about 12,700 cars, 7,200 trucks.
