MOBILE, Ala. – The U.S. Army Corps of Engineers Mobile District continues clearing high water-level navigation impacts to the Tennessee-Tombigbee Waterway (TTWW).


As of March 7, 2019, the navigation obstruction (shoaling) north of the Sonny Montgomery Lock (mile 410) has been cleared to allow a 150’ wide channel marked by buoys. Howell Heflin Lock (mile 266.1) near Gainesville, Ala. has also reopened, and all other locks along the waterway remain open at this time.


Users of the waterway should also be aware, however, that navigation obstructions remain nearby the Aberdeen Lock (mile 357), which continue to block river traffic along the TTWW. There are also a number of areas of restricted channel, marked by buoys, at the following river mile markers:


  • mile 326
  • mile 362.6
  • mile 423.1
  • mile 431
  • mile 433
  • mile 436.6
  • mile 440.3


“We appreciate the public’s patience as we continue aggressively executing our mission to clear the navigation impacts across our region,” said Wynne Fuller, chief of Operations Division, USACE Mobile District. “The shoaling and lock closures we’ve experienced are a direct result of the high waters and continued heavy rainfall over Mississippi and Alabama.”
