Historical Hydraulics Hinders Highway Headway
WSP was tasked with the drainage design of an 8-mile stretch of historical parkway. The project initially started out as a maintenance project with few areas of expansion, but as the project moved forward more changes were needed to address existing flooding and to incorporate spread improvements. Some of the many challenges of the project include minimizing impacts to the adjacent national park to maintain its historical character, lack of curb and gutter to direct stormwater flow and, working with inefficient historical inlets required by the project. This presentation will look at the benefits of improving the drainage design of the parkway for increased travel capacity within the right of way and design challenges involved of a historical parkway.
