Louisville Indiana – Kentucky Ohio River Bridges Project

https://www.youtube.com/watch?v=26r9MpVATsI Today's "Walk the Bridge" event attracted tens of thousands of people. The Louisville-Southern Indiana Ohio River Bridges Project addresses cross-river transportation needs in Louisville, Kentucky and Southern Indiana and will result in safer travel, less congestion and improved access to destinations in the region. LOUISVILLE, Ky. – Governor Steve Beshear announced that the new Ohio River bridge between Kentucky and Indiana in downtown Louisville will be named the Abraham Lincoln Bridge – connecting, as it does, the states of Lincoln’s birth and raising. “Lincoln led our nation through its bloodiest and greatest constitutional and political crisis – the American Civil War,” Gov. Beshear said. “But at the end of that national trauma, we remained a ‘United’ States of America. It’s therefore fitting that we honor Lincoln’s legacy with a bridge that further unites Kentucky, where he was born, with Indiana then Illinois, where he emigrated as a youth and grew to adulthood.” Kentucky and Indiana jointly are building the bridges project to improve cross-river mobility between Louisville and Southern Indiana. The project also includes construction of a new bridge eight miles upriver, connecting Prospect, Kentucky, and Utica, Indiana.  

St. Louis Area Flood Plains and Levees

As water rushed toward St. Louis in May 2015, attention is on geotechnical runaway development that has occurred since the floods of 1993. ST. LOUIS, — Miles and miles of bigger and stronger levees have been built along the Missouri and Mississippi Rivers since the deadly floods of 1993, and millions of dollars have been spent on drainage improvements. Building is happening on flood plains across Missouri, but most of the development is in the St. Louis area, and it is estimated to be worth more than $2.2 billion. Though scientists warn about the danger of such building, the Missouri government has subsidized some of it through tax financing for builders. The existing alignment of the Missouri River levee and embankment system is recognized to have breach/foundation distress from  underseepage and boil activity concerns as a result of hydrologic conditions and flow constrictions.  The repetitive cycle of repairing levees in place after each major flood event has resulted in increased O&M and RR&R costs, increased flood risk, and a general concern over the effective level of protection.  Levee repairs in place do not reduce flood  risk. Additionally, the current alignment of federal levees has acted to disconnect the river from its historic floodplain causing environmental degradation  and impaired habitat for fish and wildlife.    It several locations, bridges (rail and highway) and abutments, have encroached into the river’s conveyance area, increasing stages on the upstream side and increasing velocities on the downstream side, which also influence the performance of the levees.
