PROJECT MOUNT HOPE BRIDGE by Abdul Hamada, WSP The Mount Hope Bridge project is located about 2 miles north of the small rural town of Mount Hope in Sedgwick County, Kans. The bridge spans the Arkansas River and carries 279th Street West, a major collector, and is essential for the local farming community and the traveling public. Every harvest season farmers drive heavy machinery across this bridge, and, after 60 years of use, the previous eight-span, 654-ft-long, and 26-ft-wide structurally deficient bridge had to be replaced to accommodate the traffic demand. Timeline Construction of the project started in November 2014 and had an anticipated end date of November 9, 2015. The schedule was accelerated to minimize the closure period of the vital route and the impact of that closure on the farming community. The project timeline was also influenced by the Kansas Department of Wildlife and Parks requirement for construction to stay out of the wetted channel from April 1 to August 31 to protect multiple endangered fish species. In fact, the project was completed on September 30, 2015, weeks ahead of schedule. The timeline was shortened because Sedgwick County Public Works provided a temporary construction staging area for the contractor and because all environmental and hydraulic permits were acquired before the start of construction.
