(WSIL) -- Low water on the Mississippi River is forcing changes to the Dorena-Hickman ferry service.
The Kentucky Transportation Cabinet (KYTC) announced Wednesday that the ferry will temporarily be unable to transport large trucks.
Transportation officials said the river gauge at Cairo was at 13.93 at noon Wednesday. Without substantial rainfall, it's expected to stay at or below that level through mid-October.
According to KYTC, a contractor has been reconstructing the ramp at the Kentucky Landing, but the ramp hasn't yet been extended to a point where it can be used when the river level is extremely low.
"Kentucky Transportation Cabinet personnel have hauled millings to fill in at the bottom of the ramp to allow the ferry to keep operating. However, the millings are not capable of supporting the weight of large trucks," said a release from the Cabinet Wednesday.
Until further notice, the ferry is asking anyone who plans to cross with a semi or commercial box truck to first contact the ferryboat about operating conditions.
The ferry is able to continue hauling passenger vehicles and pickup trucks without disruption.
The Dorena-Hickman Ferry connects KY 1354 at Hickman, Kentucky with Missouri Route A and Route 77 near Dorena, Missouri.
