Day 185 The cribstone bridge
This the the one and only crib-stone bridge in the world. it spans between Orr’s AND Bailey’s island in mid-coast Maine.
Design of the 1,150-foot bridge was complicated by the tides in the area known as Will’s Gut. It was decided to build a cribstone bridge using granite slabs from local quarries on the border between Yarmouth, Maine and Pownal, Maine. Granite slabs were considered sufficiently heavy to withstand wind and wave, while the open cribbing allowed the tide to ebb and flow freely without increasing tidal current to any great degree. Some 10,000 tons of granite were used in the project. A concrete road (now part of Route 24) was built on top of the cribstones.
