It probably isn't a good idea to ride through a construction area but construction workers have no authority to confiscate anyone's property or fine anyone.
They would have to take the bike out of my hands and I would call the police for theft. The same is true of "fines." They only way a construction crew would get money from me is if they took it by force which is robbery.
Police are another story. They have authority to prevent you from entering and can arrest you for failing to obey a lawful order.
