Those photos are dated. The temp fences have been extended but still can be breeched. The bridge has jersey barriers - plural- at each end. Back in July there was a reporter on the local news Roundup saying that "aggressive cyclists" had been accessing the path & using it. You could hear the air quotes in his voice. Said it was ahead of schedule & could be open by late August or September. Didn't do any work on it until week of Labor Day. Put in railings.
Rode it 8 or so times before the barriers went up.
Rode by the Yarmouth end today & could see them working on the path but too far away to see what they were doing. Will be riding it Sunday to check it out.
