Here's a video that was recently uploaded to Youtube by tomsoftware regarding the Island Greenway. The in-depth video goes over the original concept which takes the bike trail from the Carolina Beach boat launch all the way down to Fort Fisher.
The original plan had a portion of the trail being constructed along the firebreak behind homes in Carolina Beach and Kure Beach. Unfortunately, some Kure Beach residents opposed the idea and the KB Town Council would not support the plan in its original form.
In case you never saw the original concept, here it is. It's a great video and in my opinion, the original plan made a lot of sense. But you can decide for yourself.
