The inspection was timed at lowest tide during daylight. The deck and soffit of Span 1 and a crawl space under Span 1 were dry. The depth of water at the toe end of the ramp measured 8.0 feet where the deck was submerged in 2.0 feet of water. The deck of Span 2 was partially submerged at lowest tide with rock slope protection underneath limiting access. A kayak, waders, wading boots, knee pads, flash lights were on site. The deck of the ferry when parked next to the toe of the bridge, life vests, strong flashlights, and a 20 foot extendible pole for both probing and use with a mirror were essential for inspections on and under the structure. The ferry operator, Yeni, was helpful in moving the ferry near the ramp areas to provide inspection access. There was litter in the channel, and partially submerged decayed boats which are noted as precautions for future inspections with kayaks, but these did not hinder access during the inspection. A complete routine bridge inspection was performed. NUMBERING CONVENTION In the Caltrans convention, the forward direction of Eight Mile Road is from west to east, and the beginning of the structure would usually be located on the west end. For the two ferry ramps, the beginning of the bridges at Abutment 1 will be designated at the tops of the levee slopes. The designation of the end of the bridges will be near the toe of the banks, in the water at high tide. HISTORY The structure was constructed in 1951 to accommodate the Eight Mile Road Ferry across Little Potato Slough which is also known as the Little Connection Slough by the US Coast Guard. DECK AND ROADWAY The bridge identification was not visible. SAFE LOAD CAPACITY The load rating for this structure is being reviewed by SM&I Ratings Branch under Work Request 13201.
