Ever driven over the ramp bridge of the I-59/20 interchange with the Red Mountain Expressway in Birmingham, Alabama? Well, you can’t anymore. Crews used explosives Sunday morning to drop the bridge 50 feet to the ground as part of a $475 million highway improvement project on the interstate. Al.com was there to record the action. It must be the season for demolition as crews in New York dropped part of the old Tappan Zee Bridge into the Hudson River last month.
