BY MATTHEW ALBRIGHT | Staff writer The oldest man-made structure in North America might be in Baton Rouge. And it turns out LSU fans have been tailgating on it for decades. We knew the Native American mounds in the heart of campus were old, but new research suggests they go back 11,000 years — and you're unlikely to find anything older on our side of the globe. When a crack in the Sunshine Bridge caused one lane to close, some people wondered if a bigger closure was going to happen. Well, it is: the bridge is going to close entirely this weekend for repairs. This story explains why, and how many people could face traffic woes. Hopefully Baton Rouge won't get hit with 250 mph winds, but if it ever does, this new building should be able to stay standing. The idea is that first responders can hunker down there, ride out a storm, and then be ready to roll as soon as it's safe. Here's what the building looks like and how city leaders hope it will help. |
