The Tampa-Hillsborough Co. Expressway Authority on May 25 filed a countersuit at the Hillsborough County Circuit Court in Tampa against locally based PCL Civil Constructors. PCL, which built and rebuilt reversible lanes on the Selmon Crosstown Expressway, filed suit April 1 against the agency. It seeks $21 million that it claims it is owed and alleges breach of contract.

In the countersuit, the authority contends that PCL owes a refund of $6 million. According to Authority General Counsel Patrick Maguire, five items were paid either as a result of fraud, misrepresentation or deliberate overbilling.
