Madison, Limestone and Morgan counties rank in the top 15 in Alabama in the number of bridges they have on their roadways.

Some are obvious, the Interstate 65 bridge that crosses the Tennessee River and connects Limestone and Morgan counties near some of the area’s top manufacturers, the Hudson Memorial Bridge in Decatur on U.S. 231 and the Clement Clay Bridge on U.S. 231 that also cross the Tennessee River are among the most traveled with commuter traffic to major employers such as Redstone Arsenal and the advance manufacturers.

Others are smaller bridges in rural areas. What kind of shape are they in?

According to the Federal Highway Administration, 559 of Alabama’s 16,176 bridges are judged to be in “poor condition. That includes some in the Huntsville area.
