Coal and petroleum coke barges on the lower end of the Ohio river have fallen more than 11 hours behind schedule, primarily because of repairs to a major lock and dam, and more delays are expected.
The large chamber at Lock 52 near Brookport, Illinois, closed yesterday for repairs. The smaller chamber remains open but traffic is moving through at a slower pace. The main chamber will be closed until 11 September, reopen for three days to alleviate the expected queue of barges and then shut again between 14-25 September.
Barge operators moved coal ahead of the closure, anticipating major delays. Repairs at Lock 52 during the last few summers sometimes held up coal barges for days.
Last September 1.6mn short tons (1.6mn metric tonnes) of coal, coke and lignite moved through Lock 52, US Army Corps of Engineers figures indicate.
Coal traffic this year through July is down by 24pc, falling to 9.2mn st from 12.1mn st last year.
