A pile-driving template will be temporarily positioned along the downstream side of the bridge on the right descending bank, encroaching up to 15 feet into the channel. The template will be lighted at night. During active work hours, the horizontal navigational clearance through the bridge span will be reduced to 200 feet and restored to normal clearance at night. Mariners are requested to contact M/V SAM B., via VHF-FM Channel 16 one-hour before arrival at the bridge to arrange passage.
