Railroad Bridge, St. Johns River: Florida East Coast Railway requested a temporary deviation from the operating schedule that governs the Florida East Coast Railway Bridge, St. Johns River, mile 24.9, Jacksonville, FL. The bridge is a single leaf bascule railway bridge with a five-foot vertical clearance in the closed position. The bridge currently operates under 33 CFR 117.325. The deviation period is from 7:00 a.m. on January 11, 2017 to 6:00 p.m. on February 10, 2017. During this period the Bridge is allowed to remain closed to navigation from 7:00 a.m. to 11:00 a.m., and from 1:00 p.m. to 5:00 p.m. on Wednesday January 11th , from 7:00 a.m. to 12:00 p.m., and from 2:00 p.m. to 5:00 p.m. Thursday January the 12th, from 8:00 a.m. to 12:00 p.m., and from 2:30 p.m. to 6:30 p.m. on Friday January 13th , from 7:00 a.m. to 11:00 a.m., and from 1:00 p.m. to 5:00 p.m. Wednesday January the 18th and Thursday January 19th , and from 8:00 a.m. to 12:00 p.m., and from 2:30 p.m. to 6:30 p.m. Friday January the 20th, 2017. Additionally, the bridge will be allowed to remain closed to navigation from 7:00 a.m. Monday January 30, 2017 through 6:00 p.m. on Friday February 10th, 2017. The Coast Guard coordinated this closure period with the bridge owner and the waterway users. The bridge will not be able to open for emergencies; the small boat span can be used as an alternate route for vessels unable to pass through the bridge in closed positions. The Coast Guard will also inform the users of the waterways through our Local and Broadcast Notices to Mariners of the change in operating schedule for the bridge so that vessel operators can arrange their transits to minimize any impact caused by the temporary deviation.
