Perth will be ringed by roadworks as four nights of inspection works on the Friarton Bridge and M90 flyovers join major works on the city bypass.
The bridge inspections begin on Monday in an effort to ensure the bridges continue to operate safely.
Specialist teams will carry out overnight inspections on the bridges and slip roads of the Craigend Interchange and carry out routine checks and maintenance of the Friarton Bridge.
Maintenance works will include cleaning the bridge deck joints, channel and verge, as well as drainage clearance.
The inspections are scheduled to take place for four nights, starting on Monday April 3, between 7.30pm and 6.30am.
Traffic restrictions will be put in place in order to allow BEAR Scotland teams to carry out the works safely.
Diversion routes will be in place when required and signs will be erected in advance to notify road users and some disruption is expected.
No works will be carried out during the daytime.
On the opposite side of Perth, significant roadworks are underway between the Broxden and Inveralmond roundabouts to create the new A9/A85 junction.
Motorists have been experiencing delays of between 10 and 15 minutes as a result of the massive infrastructure project.
It will pave the way for Perth’s westward expansion, including hundreds of new homes and a new secondary school, Bertha Park.
BEAR Scotland’s Andy Thompson said: “These maintenance works are part of our commitment to ensuring the north east network continues to be of the highest standard.
“We aim to carry out works with minimum inconvenience to motorists and so we’ve planned these works to take place overnight to limit any impact on road users.
“Every effort will be made to minimise the duration of the closures each night in order to reduce disruption to motorists.”
Nonetheless, Mr Thompson urged motorists to plan their journeys in advance and follow the signed diversions.
