U.S. Gulf:
Dredging was expected in the
Port Allen Lock area on July 10-14, triggering likely delays of eight hours or
more. The operation was scheduled to run on a 24-hour schedule. Following the
conclusion of dredging, the lock was anticipated to close to daylight-hour
navigation on July 20-30 for repairs and maintenance, blocking transit daily
from 6:00 a.m. to 6:30 p.m. Twenty-one tows were reported queued to lock on
July 12, with waits posted up to 18 hours.
Commercial traffic was
stopped at the West Canal’s Mile 231 during the week from 5:00 a.m. to 9:00
a.m., and again between 3:00 p.m. and 7:00 p.m., due to a bridge closure. No
timeline for a return to normal operations was available on July 12.
Monday-through-Thursday
travel restrictions remained in place at Calcasieu Lock through July 11,
blocking commercial traffic daily between the hours of 7:00 a.m. and 6:00 p.m.
The project, which began on March 22 and is anticipated to run into late August,
was paused temporarily on July 11.
Following a pause due to
high water in the area, guidewall construction efforts at Bayou Sorrel Lock
were expected to resume on July 11, limiting navigation between 6:30 a.m. and
5:00 p.m., Monday through Friday, through February 2023. Weekday delays were
projected up to 12 hours, with travel times expected to normalize on Saturday
and Sunday. Waits were observed in the 4-11 hour range during the week.
Repairs to the Bayou Sorrel
Bridge resumed during the week, with an expected conclusion slated for
second-half August. Travel through the area was expected to be unavailable
Monday through Thursday between 7:00 a.m. and 11:00 a.m., and again from 1:00
p.m. to 5:00 p.m.
Shoaling continued to prompt
10-foot draft restrictions at Miles 113-117 of the Atchafalaya River. Tows were
limited to 600-foot lengths as well, while barge strings measuring longer than
400 feet were advised to travel with an assist boat. Width limits of 70 feet
were also in effect. Tows were suggested to bypass the restrictions by
traveling through the Port Allen Route. The presence of recently revealed
underwater pipelines triggered a shutdown at Little Island Pass, Middle Island
Pass, and Riverside Pass.
Unassisted lockages were
subject to ongoing length and width restrictions at Algiers Lock, limiting tows
to four standard barges or two 30,000 mt tankers per turn. Longer strings were
permitted to lock when accompanied by an assist tug. Delays fell in the 8-15
hour range through the week.
Ongoing intermittent travel
restrictions at Belle Chasse Bridge were expected due to construction work
scheduled through the end of the year. Travel stoppages were likely to run up
to 12 hours. Belle Chasse Bridge is located at Mile 3 in the West Canal.
Delays at Industrial Lock
were noted in a wide 3-13 hour range during the week. Intermittent 14-hour
waits were seen at Brazos Lock.
Mississippi
River:
Reduced water levels
continued to drive draft limits and reduced towing maximums on the lower
Mississippi River, although conditions were said to be improving. Southbound
drafts were capped at a reported 12.5 feet, an increase from 11-11.5 feet one
week earlier, while tows traveling upriver remained limited 10.5-foot drafts.
Maximum barge counts were reduced by 10-15%.
Extreme heat in the lower
Mississippi River Valley was noted driving minor delays to travel and
associated outdoor commercial activities. A heat advisory on July 13 warned of
dangerous temperatures in Louisiana, Mississippi, and southeastern Arkansas.
Rock-laying work underway
since May 10 at Mile 807 was heard to continue outside of the navigational
channel, with limited impacts to commercial travel reported.
Power line work was underway
at Mile 107, limiting daytime travel through the area through at least July 20.
One-way traffic was available daily from 4:00 a.m. to 7:00 a.m., and again from
1:00 p.m. to 4:00 p.m. Travel was completely unavailable from 7:00 a.m. to 1:00
p.m.
Old River Lock is slated to
shut from Aug. 30 through Nov. 13 for miter gate installation, halting all
travel through the site. Tows seeking access to the Red River should detour
through the Atchafalaya River. Old River Lock is located at the lower river’s
Mile 305.
Wait times were observed up
to six hours at Lock 24 during the week.
Illinois
River:
A repair and maintenance operation
in progress since May 9 at Brandon Road Lock is scheduled to continue through
Sept. 8, according to a Corps posting. Transit is restricted to overnight hours
through Aug. 14. The site will completely close to navigation from Aug. 15
through Sept. 4, followed by a return to overnight-only movements on Sept. 5-8.
Standard, 24-hour navigation is set to return on Sept. 9. A 70-foot width limit
is in effect for the entirety of the operation. Wait times were counted as high
as 15 hours during the week.
Wickets continued to be
reported in the raised position at Peoria Lock, prompting vessels to lock
through that location. Rising water levels allowed wickets to be lowered at
LaGrange Lock, shippers said. As a result, tows were able to transit LaGrange
via the nonlocking navigational pass. Peoria Lock waits were noted up to 14.5
hours.
Marseilles Lock delays were
reported up to 11 hours during the week. Starved Rock Lock wait times topped
out at nine hours through July 13.
Ohio River:
Shoaling conditions
continued to be reported at the Ohio River’s Mile 926, limiting navigation
through Miles 920-926. Transits through the area were considered on a
case-by-case basis. Maximum draft limits were set at 10 feet for the length of
the river. No timeline for a return to normal operation was immediately
available.
The Cannelton Lock main chamber was reported shutting
on July 5 for miter gate replacement, forcing tows to pass through the smaller
secondary chamber through an estimated Nov. 11. Corps data showed delays in the
13-23 hour range on July 12-13.
Hannibal Lock primary chamber miter gate and quoin
repair was reported in progress from July 5 through Oct. 8, limiting vessels to
the use of the secondary chamber.
The Tennessee River’s Kentucky Lock saw typical wait
times in the 8-13 hour range for the week, with intermittent spikes registering
up to 18-21 hours. Wilson Lock delays peaked at 21.5 hours on July 12-13.
Miter gate machinery repair operations at Cheatham
Lock on the Cumberland River were scheduled to run through Aug. 5. Travel
shutdowns at the site were noted following a repeating 14-day pattern, in which
the site is closed to navigation for 11 days, followed by three days of
unrestricted travel. The industry is expecting significant delays while the
project is underway.
Arkansas
River:
A Norrell Lock daytime
travel shutdown was in effect through July 21 due to planned maintenance,
blocking movements daily between 7:00 a.m. and 7:00 p.m. The travel outages
were scheduled to repeat on Aug. 1-10; Aug. 21-Sept. 21; Oct. 20-Nov. 18; Nov.
29-Dec. 23; and Jan. 3-31, 2023.
The lock is anticipated to
undergo a complete shutdown running from Sept. 30 through Oct. 9, although a
delay to that timeline was reportedly under consideration.
Planned repairs at Joe Hardin Lock will block marine
travel from 7:00 a.m. to 7:00 p.m. daily on Sept. 12-19, and again on Sept.
28-29. A complete shutdown of the lock was planned to run from Sept. 30 through
Oct. 9.
