Architect Bernard Zyscovich initially unveiled a plan to convert the Rickenbacker Causeway into a "scenic road through a park" a couple of summers ago, but it included dropping the number of driving lanes from three to two.
New lanes would be constructed solely for bikes, and a striking entranceway meant to link up with the planned Underline park would be built.
The dedicated biking and jogging lanes would then continue on into Key Biscayne. An observation deck is called for at the William Powell Bridge.
While the renderings and concept make me want to become an avid cycler, the question would be over who's footing the bill.
Zyscovich presents the plan to the Key Biscayne Village Council later this month.
