Observation Deck
Two observation decks were added by adding two additional oak planks to provide a platform approximately 30" wide. A 2x6 railing was added to one span by extending the piers to a 36" height with 2x4's bolted to the 4x4 vertical supports. A 3/16" cable with turnbuckles was added as shown to provide additional support to the structure.
