Downtown HB and Lido Isle are quite a distance apart. Is there something going on in downtown HB? If its just the usual rabble-rousers that like to protest at the foot of the HB Pier, then that's nothing to worry about. But if HBPD shuts down the PCH/Main St intersection, then you southbounders on PCH can just turn inland, go up to Orange, turn right and go south on that to 1st street (after you cross Main St, and where Orange turns into Atlanta) and turn right down 1st to PCH. You can also keep going along Atlanta to Beach Blvd, then down Beach Blvd to PCH. If northbound, just do the reverse.
