Roadworks on the A92 near Glenrothes in Fife will start next week, with a lane closure expected to be in place for six weeks.
It follows changes at the Balfarg junction earlier this year, the result of an £850,000 investment into safety and performance.
Several serious accidents have taken place at the junction in the last 10 years, including the death of a child.
The next phase of safety improvements will see a new bus stop layby installed on the southbound carriageway, along with cycle and pedestrian facilities.
Some works are also to be carried out at the Balfarg junction to implement measures identified by the road safety audit of the completed scheme.
Since completion of the first stage of work teams have been monitoring performance, with data suggesting the junction continues to perform well with “minimal impact on journey times being reported”.
As a result of the next phase of roadworks on the A92 near Glenrothes, a lane closure on the southbound carriageway between New Inn Roundabout and Gateside Cottage will be put in place to protect workers and motorists.
It is expected that roadworks will last for around six weeks from Monday October 4.
Next stage of safety improvement to begin Monday
Additional traffic management may also be required throughout the roadworks, but BEAR Scotland said this will be limited to off-peak working to minimise delays where possible.
Campaigners have long called for safety improvement on the road, with some locals suggesting their concerns had been ignored.
Commenting on the improvements, Ian Stewart, BEAR Scotland’s north east representative, said: “This final phase of improvements completes the project carried out earlier this year to install a new pedestrian crossing and new traffic signals on the A92 at Balfarg junction.”
Pedestrian crossing
He added: “The investment from Transport Scotland has created a safer junction for vehicles, pedestrians, cyclists and other road users.
“The traffic management planned for this phase of works is essential to keep everyone safe during the project, however our teams will do all they can to keep any disruption to a minimum as much as possible.
“We would like to thank motorists and residents around the junction for their continued patience during this project.”
Motorists are also being asked to plan ahead by checking Traffic Scotland for up to date journey information.
