Roadworks on the Friarton Bridge are due to last for three weeks.
Roadworks on the Friarton Bridge are being restricted to avoid peak periods to cut down on potential delays.
The bridge is used by 35,000 motorists a day and the three weeks of roadworks are part of ongoing maintenance on the M90.
The work on the bridge began on Sunday and will be carried out from 9.30am to 3.30pm, Monday to Thursday, and 9am to 4pm on Sundays.
It is part of approximately £650,000 worth of improvements and maintenance work being carried out on the M90 from Kinross up to the bridge.
Motorists using the route are being encouraged to check the Traffic Scotland website for up-to-date travel information and to allow extra time for their journeys.
To enable the work to take place safely and for the protection of road workers, single-lane closures will be in effect during the construction period.
