The Challenge
Replacing a Century-Old Bridge
The existing SR 715 crossing over McMichael’s Creek consisted of a two-span stone masonry arch bridge built more than 100 years ago. With a 15-ton weight restriction in place, replacing the aging structure was a key objective of the project.
Developing the replacement structure required reliable technical information. Understanding subsurface conditions and establishing accurate survey and Right-of-Way information were important components of this phase.
The Solution
Supporting Final Design and Construction
AEG, a SOCOTEC Company, provided multidisciplinary technical expertise during final design and continued its involvement through the construction phase.
Services included:
- Geotechnical engineering
- Supplemental surveys to support the Final Right-of-Way Plan
- Right-of-Way services
- Preparation and administration of the boring contract
- Development of boring specifications and a boring plan for the replacement structure
- Laboratory testing in AEG’s AASHTO Verified and USACE Validated facility
- Preparation of the Final Structure Foundation Report
- Review of shop drawings during construction
- Review of geotechnical design parameters
The project replaced the existing crossing with a single-span concrete arch culvert.

The Results
Reopening SR 715 Without Weight Restrictions
In 2024, the new crossing opened to traffic without the 15-ton load limitation that applied to the former structure.
AEG’s technical oversight contributed to verifying that the replacement met the project’s safety and performance requirements.
This continued involvement provided technical continuity through key stages of the bridge replacement.
