Gasconade County Bridge Replacement, Gasconade County, Missouri
Gasconade County hired PSBA to design a new structure crossing the Bourbeuse River.
The Bourbeuse River drains approximately 150 square miles at this location. Topography in Gasconade County promotes rapid drainage, which correlates to rivers quickly rising and dropping even during small storm events.
The new structure utilizes concrete pre-stressed I-girders in a 74’-90’-44’ configuration sitting on a combination of pile, drilled shaft, and spread footing substructures.
PSBA was responsible for the Hydraulic Study, Right-of-way documents, Structural Design, Roadway design, and Construction Administration.
