FDOT Policy
Current FDOT policy on roundabouts states the following:
Only single-lane and two-lane modern roundabouts are to be constructed on the State Highway System. Partial three-lane roundabouts may be acceptable under certain conditions.
Roundabout evaluation is governed by the Intersection Control Evaluation (ICE) process as outlined in the FDOT ICE manual.
