ODOT’s PID 104156 at Brush Creek
Monroe Township, Ohio
Resolving roadway damage and slope instability at Brush Creek Road.
TTL, now part of CT Consultants, worked with Stantec, who was awarded the design of ADA-041-21.42, PID 104156, ODOT programmatic for ODOT District 9.
We performed the subsurface exploration, including instrumentation using inclinometers, and prepared plans to remediate a roughly 500-foot slope failure.
The project, on the east side of SR 41 with a drilled shaft retaining wall, consisted of 3-ft diameter drilled shafts, spaced 5-ft on center and embedded 10 feet in the underlying bedrock. The surface elevation of the roadway was generally 55 ft above Brush Creek, with a moderate degree of slope steeper than 2:1 in some areas.
In addition to the wall, the design included a guardrail, drainage, and pavement repair.
