Connecting Ohio and Kentucky
CTL Engineering played a significant role during the construction of the U.S. Grant Bridge in Portsmouth, Ohio by authoring the project Quality Control Plan with an addendum to include Concrete Maturity Testing. CTL also provided creep testing, concrete mix designs including maturity testing and field and laboratory testing of all cast-in-place concrete used for the bridge from the top of the caissons to the top of the towers.
