Right Turn Only Lanes
Nathan asked: You’ve said that FDOT no longer uses undesignated bike lanes. Is this why I’ve been recently seeing bike lanes that exist only to the left of right-turn lanes, and revert to shoulder before and after (forcing a cyclist to use the shoulder after the intersection, since it’s illegal to change lanes in an intersection)? I’ve seen these both at new right-turn lane installations on existing roads: http://maps.google.com/maps?hl=en&ll=29.777816,-81.641454&spn=0.008325,0.016512&gl=us&t=m&z=17&layer=c&cbll=29.777492,-81.641273&panoid=krMJ6TrqfD7Owavx0C42MQ&cbp=12,335.97,,0,8.36
and on recent widenings of rural highways: http://maps.google.com/maps?hl=en&ll=30.605358,-86.950672&spn=0.008255,0.016512&gl=us&t=m&z=17&layer=c&cbll=30.605241,-86.950558&panoid=X4-X3CdhvVO_ptMWbvB8SA&cbp=12,330.83,,0,9.24
The intersection you show is the correct installation of bike lanes to the left of the right turn only lane.
FDOT Plans Preparation Manual
8.4.1 – Bicycle Lanes
At intersections with right turn lanes, the bicycle lane shall continue adjacent to the through lane; between the through lane and the right turn lane, and shall be 5 feet in width for new construction and reconstruction projects.
This configuration usually provides for a continuous bike lane through the intersection and minimizes the conflict with right-turning vehicles. It does require moving from the paved shoulder bike lane to the next lane before entering the intersection.
If the paved shoulder is not marked for the use of bicycles, bicyclists are not required to use it.
