OLD FIVE ROAD BRIDGE

Project Overview

Morgan County hired McClure to design a replacement structure on Old Five Road using county funds to submit for Soft Match Credit with the Off-System Bridge Replacement and Rehabilitation Program (BRO). The design consisted of precast concrete box girders on a Geosynthetic Reinforced Soil Integrated Bridge System abutments keyed into limestone. The innovative design uses masonry blocks, geotextile fabric and gravel in layers to create a rigid bearing surface to support the superstructure. The GRS-IBS Abutment also reduces the potential for scour. McClure also provided construction observation and permitting services.

Project Highlights:

• Earned Soft Match Credit to be used for future BRO projects.
• Innovative GRS-IBS Design.
• Restored a vital connection within the county
