RANDOLPH COUNTY GRS-IBS BRIDGE
McClure provided surveys, permits, railroad coordination, preliminary and final bridge design, and construction observation services to replace Bridge No. 3670020 utilizing the BRO program. The existing structure was a wooden bridge over the Kansans City Southern Railroad Randolph County, Missouri, and had been repaired due to collision damage and structural deficiencies. The final design included a single span structure with Geosynthetic Reinforced Soil (GRS) abutments for the substructure and precast concrete box beams for the superstructure with a concrete deck. A concrete crash wall was also included in front of each abutment. This innovative bridge design, known as GRS-IBS, stands for Geosynthetic Reinforced Soil – Integrated Bridge System, which was the second one completed in the state of Missouri and the first one over a railroad. Additional width provided by the new structure allowed for two-way traffic and large agricultural equipment.
- Second Geosynthetic Reinforced Soil-Integrated Bridge System constructed in Missouri.
- Design involving aggregate and fabric faced with block wall.
- Concrete box girders.
- Innovative approach saving time and money by simplifying construction process.
