The £580,000 investment from Transport Scotland will involve the replacement of the bridge waterproofing, resurfacing of 60 metre of carriageway, replacement of the expansion joints as well as conducting any necessary concrete repairs.
The bridge carries the M90 over the B9112 (Necessity Brae) and was constructed in 1973, these planned works will ensure the bridge continues to function safely for years to come.
During the project the M90 will remain open, however, to keep roadworkers and motorists safe during the upgrades and to complete the work in the shortest possible timescale, a contraflow traffic management arrangement will be in operation during the bridge repairs. This traffic management will be in place full time for six weeks.

Phase one will commence on the westbound carriageway (towards Broxden) on Monday 13 June for three weeks with single lane traffic in each direction travelling in the opposite carriageway.
Phase two will commence on Tuesday 5 July, with works switching to the eastbound carriageway for a further three weeks until 30 July.
Road users are warned to expect delays while the work is underway and are encouraged to plan ahead.
Consultation has been carried out with Transport Scotland, Perth and Kinross Council, Community Councils and transport operators to inform them of the plans for the project in advance.
Commenting on the works, Ian Stewart; BEAR Scotland’s North East Representative said: "This £580,000 bridge improvement project will allow our teams to carry out essential maintenance, ensuring the M90 Necessity Brae Bridge continues to operate safely into the future.
"We have programmed the works at this time of the year to take advantage of the school holidays when traffic is generally lighter, and the weather is more likely to be better for the installation of the waterproofing system.
"The traffic management is essential for ensuring the safety of our work force as well as motorists, and our teams will do all they can to carry out the work as quickly and safely as possible. We advise road users to abide by all traffic or speed restrictions put in place during the work for their safety, and to use both lanes when queuing to help reduce congestion.
"We thank road users for their patience during these essential works as there will regrettably be disruption. We would encourage them to plan their journeys in advance by checking the Traffic Scotland website before they travel and allowing some extra time to reach their destination."
