Motorists have been reminded to consider alternative travel arrangements this weekend as work continues on the Forth Replacement Crossing project.
Heavy tailbacks are expected as the M90 will be reduced to just one lane southbound.
The traffic management scheme could result in potential delays of up to two hours or more.
These restrictions are in addition to those in operation on the M90 on weekdays, and more significant delays are expected during these weekend works as the southbound carriageway is reduced to one lane.
These traffic management restrictions, which were also in operation last weekend, will be in place between 8pm on Friday, April 27 and 6am on Monday, April 30 and the contraflow will also be in operation for the weekends May 4 to 7 and May 11 to 14.
Motorists are urged to avoid the area and use alternative routes or modes of travel at these times.
To mitigate the impact of these works, ScotRail is providing additional capacity on 28 weekend services which cross the Forth Rail Bridge.
The train operator has also introduced the first-ever off peak season ticket which is designed to encourage more people to travel by train between Edinburgh and stations in Fife, when the major traffic management scheme is in force
Transport Scotland said the works are necessary for the resurfacing of the southbound carriageway as part of the Forth Replacement Crossing project and are expected to result in significant delays.
