"Site Characterization for the First East Coast Expressway (SR 23) in St. Johns and Clay Counties, Florida"

This event is sponsored by FAMU-FSU College of Engineering - Department of Civil & Environmental Engineering.

Abstract: An extensive geotechnical investigation (i.e., field and laboratory tests) was recently completed to characterize the subsurface conditions along the alignment of a new expressway in St. Johns and Clay Counties, Florida. The 6.5-mile-long design-build project will be part of the 46-mile-long First Coast Expressway (SR 23) that is currently under construction, which will connect I-10 in western Jacksonville to I-95 north of St. Augustine. The purpose of the field and laboratory tests was to support the design and construction of the roadways, mechanically stabilize earth (MSE) walls, and bridges (including a new 1.75-mile-long bridge over the St. Johns River). This presentation will show the results of the field and laboratory tests and will highlight some of the challenges and lessons learnt during our investigation.
