Monroe County will be closing the public boat ramp located on the bayside at the end of Blimp Road on Cudjoe Key at mile marker 21.2 beginning Thursday, Feb. 5 at 7 a.m. The closure is expected to last for approximately 4 months to allow for environmental mitigation work to be completed at Tarpon Belly Keys as part of the Taxiway A improvement project at the Key West International Airport. The boat ramp will be used as a staging area for the project. The county anticipates the boat ramp will open prior to lobster mini-season at the end of July.
