Stage one of the project, valued at £9m, is expected to last up to one year with main construction due to get underway next summer.
The new road north of Perth will connect the A9 to the A93 and A94 north of Scone.
It will unlock key development land and direct unnecessary traffic away from the city centre, creating a better experience for visitors and local drivers.
BAM Nuttall’s submission included commitments to pay all employees working on the project at least the Real Living Wage, and a significant reduction in the carbon footprint of the scheme.
Martin Bellamy, Managing Director, BAM Nuttall said: “Our proposal combined an understanding of the environmental sensitivities of this location with innovative methods that will improve air quality, reduce carbon and boost biodiversity throughout the lifecycle of the scheme.
“We are also working collaboratively with our supply chain partners and engaging with local stakeholders and communities to ensure that we maximise opportunities for local development of skills and employment delivering positive social impact.”
