Essential drainage work will begin near Kincardine tomorrow.
The work is to repair a culvert crossing under the A977 that has been the cause of recent flooding just past Broomknowe Drive.
It will mean the closure of the A977 on Saturday, September 7, for two days.
Signed diversion routes will be in place for both eastbound and westbound traffic.
Traffic from the east will be diverted at the A985 Longannet to cross the River Forth over the Kincardine Bridge and then travel on the Clackmannanshire Bridge to join the A977 at the Kilbaggie Roundabout.
Westbound traffic will be directed along the reverse route.
Local access to Kincardine will still be possible during the operations.
Alasdair Allen, senior operations manager for BEAR Scotland said: “For the safety of road users and road workers alike, a road closure is required to undertake these works effectively and efficiently.
“The damaged section of the culvert is in the middle of the A977 and is some 1.5m deep.
We would advise motorists to plan well ahead, check the Traffic Scotland website for up to date travel information and allow additional time for their journeys.”
