Collier County commissioners unanimously approved on Tuesday the replacement of 10 bridges east of Immokalee and Ave Maria for nearly $27 million. The source of funds for the bridge replacements is the one-cent infrastructure sales tax, which was approved by voters in 2018 "to enhance safety, mobility and hurricane preparedness," according to an executive summary of the project. In Collier, bridges are replaced when they fail to meet certain standards, Marlene Messam, principal project manager with the Transportation Engineering Division, wrote in an email Tuesday. Five bridges on Immokalee Road, four on Oil Well Road and one on Countyline Road were built between 1948 and 1953, according to the Florida Department of Transportation.
