Two sections of the A90 and two sections of the M90 at Barnhill near Perth will experience diversions and traffic calming measures to allow resurfacing works over the next four weeks.
The £1.2 million investment by Transport Scotland will see sections of the carriageway resurfaced at Barnhill Circulatory, with the project beginning on Sunday, February 20.
To ensure minimum disruption to motorists, the project is taking place in phases.
From Sunday, February 20 to Saturday, February 26 work will take place on the M90 junction 11 northbound off-slip.
The off-slip will be closed from 7.30pm on Sunday until 6.30am on the Saturday.
Motorway traffic will be diverted to the nearby Kinfauns Junction and back.
Traffic from Perth wishing to join the southbound M90 will also be diverted via the Kinfauns Junction.
A northbound nearside lane closure will also be in place across the M90 Friarton Bridge.
Work will then begin on the A90 Walnut Grove to Barnhill southbound section from Sunday, February 27 to Monday, March 7.
For safety, a contraflow system will be in place between Walnut Grove to junction 10 during this phase from 7.30pm on the Sunday until 6.30am on the Monday.
Single lane traffic will be travelling in both directions on the northbound carriageway while the A90 southbound carriageway is resurfaced.
The junction 11 southbound off-slip will be closed throughout this phase of the project, with motorway traffic being diverted to junction nine at Bridge of Earn and back.
Non-motorway traffic will be diverted via the local road to Walnut Grove.
Preparatory operations for the installation of the contraflow will be carried prior to the works commencing.
From Sunday, March 13 to Thursday, March 17 works will take place at the M90 junction 11 southbound on-slip.
The on-slip will be closed from 7.30pm on March 13 until 6.30am on March 17.
Traffic from Perth wishing to join the southbound M90 will again be diverted via the Kinfauns Junction.
Then the final phase will take place at the A90 Barnhill Circulatory westbound from Friday, March 18 to Monday, March 21.
From 7.30pm on March 18 until 6.30am on March 21, the Barnhill Circulatory westbound (from A90 South to Perth) will be closed to ensure the safety of roadworkers and motorists.
Traffic will be diverted to junction nine at Bridge of Earn and back up.
Bus services will be managed through the site to allow them to continue to run in this area to reduce the impact on the travelling public.
Non-motorway traffic will also be accommodated at these times.
BEAR Scotland’s north east unit representative Ian Stewart said: “This £1.2M investment from Transport Scotland will see works completed across busy sections of the A90 and M90 near Barnhill which will help address defects and greatly improve the road surface for motorists.
“The closures in place are necessary to protect our operatives and road users, however we’ve taken steps to minimise disruption for motorists as much as possible during the improvements by programming the works to take place in phases.
"Our teams will do all they can to complete the works as quickly and safely as they can, and we thank road users for their patience in advance while we complete these projects.
“We encourage motorists to plan ahead before setting out by checking the Traffic Scotland website for up to date travel information.”
