The public is being asked for their views on how to improve Aberdeen's "worst roundabout".
The Haudagain roundabout is a congestion hot spot
The Haudagain is renowned in the city for lengthy tail backs at rush hour, bringing headaches for commuters.
Aberdeen Council has organised an exhibition in the Henry Rae Community Centre from the 24 to 28 July on options for the A90/A96 roundabout.
Brian Adam MSP urged as many people as possible to provide comments to help ensure ministers allocated funding.
The Nationalist said: "I do hope that this consultation is not just a stalling exercise and that we will see tangible change at this traffic black spot sooner rather than later."
Aberdeen City Council commissioned a study on behalf of the Scottish Executive and Nestrans to investigate improvements to the roundabout.
The exhibition will include provisional designs of each option along with a description of their predicted performance.
The information is also to be displayed on the council's website.
