- Antioch Road Bridge over Indian Creek
As part of the design team for the interchange design at I-435 and Antioch Road, Burns & McDonnell was responsible for the hydraulic analysis and design of all of the structure crossings of Indian Creek. The widening of Antioch Road in the vicinity of the interchange extended north, requiring the reconstruction of the bridge. The project was designed jointly for the Kansas Department of Transportation and the City of Overland Park as part of the System Enhancement project for the new interchange.
The four-span, 210-foot haunched concrete slab bridge has a variable width-roadway to accommodate the widening transition at the interchange approach. Sidewalks are included on each side of the bridge, which is heavily used by an active pedestrian community. Aesthetic enhancements include concrete form liners on the traffic barriers and the use of ornamental pedestrian railings.
The superstructure is supported on column bent piers with web walls. Columns are supported on drilled shafts. Integral abutments supported on steel H-piles are constructed on each end. The structure was designed under AASHTO Load Rating Factor Design Specifications.
