Wait times at Bayou Sorrel Lock stretched to an average 4-6 hours for the week, with five boats in line to lock. Shippers said Bayou Sorrel was scheduled to close for four out of every 12 hours in an effort to avoid both high-water restrictions and flood control measures. Additionally, the lock was closed to transit from 8:30 a.m. to 3:30 p.m. on Dec. 2.
Delays at Inner Harbor Navigational Canal Lock were called 9-13 hours for the week. The lock was closed between the hours of 8:30 a.m. and 3:30 p.m., Nov. 30 through Dec. 3, and nine boats were queued for locking on Dec. 2.

Painting and maintenance activities on the books through April 30, 2016, at the West Port Arthur Bridge have reduced transit clearance by a minimum of three feet, shippers said.

Upper Mississippi River: Water levels rising above the 25-foot mark at St. Louis triggered high-water actions beginning Nov. 29. A safety zone was established at Miles 179-184, and southbound tows longer than 600 feet were limited to daylight-only transit.
Lock 27 transit times were called 2-4 hours, with four boats in line for locking. Wait times at Lock 20 were quoted at an hour or less, and Mel Price Lock delays were 1-2 hours, with two vessels waiting for transit.

Tows transiting Thebes will be capped at 15 barges during daylight hours while work is underway. Tows will not be restricted during nonworking hours. Construction is slated to continue through mid-February.
