Hoover, AL – Highway crews will start working Monday night to repair a ramp leading from Interstate 65 to I 459 in Hoover. That's an area heavily traveled by commuters as well as holiday shoppers this time of year. The Alabama Department of Transportation plans to complete the work by Friday morning. The ramp will be closed during nighttime repairs with detours posted, but it will be opened during the day. A 40-foot, 45,000-pound drive shaft fell from a truck Thursday night, punching two holes in the bridge. One hole is three by 10 feet; the other is two by six feet. Pieces of concrete also fell from the bridge and slightly injured a motorist on I 65 North. Hoover Mayor Tony Petelos says the repairs will be a necessary inconvenience.
