Roadway and Bridge Case Studies

Soil Nail Wall

NC-143 Beech Creek to Appalachian Trail | Robbinsville, NC

Schnabel was contracted to design and install 189,000 SF of permanent soil nail retaining walls and temporary shoring along the widened NC-143 in Robbinsville, NC.  The wall and the landbridge being installed by Blalock Construction will allow hikers and wildlife to safely cross the highway above the traffic flow.


I-275/SR93 Franklin Bridge | Tampa, FL

Schnabel installed 130,000 SF of steel sheet piling and 550 rotary PI tiebacks into a sandy fill soil along Tampa Bay.  The wall supports the widening of I-275 and the addition of a bike path and pedestrian path next to the bay.  The project is an extension of the Howard Franklin Bridge Replacement for the Florida DOT.
