Crossdrain Culvert Replacement Requires Temporary Closure of CR 16A in St. Johns County CR 16A A deteriorated metal crossdrain culvert located in the vicinity of 6700 CR 16A has become a safety issue and requires replacement. Due to the size of the pipe being replaced and the size of the equipment required to complete the job, it is necessary to close CR 16A beginning Monday, July 21. The replacement is scheduled to occur during the summer while school is out in order to minimize the impact on residential traffic for the surrounding neighborhoods. The road is scheduled to open in August. For more information, please contact the St. Johns County Engineering Department at (904) 209-0110.
