A new section of carriageway has opened to motorists as part of the Aberdeen Western Peripheral Route (AWPR) project.
Traffic from the existing A90 between Bridgend and Foveran was diverted to run on the new 3km section of carriageway on Sunday.
The new carriageway will eventually become dual carriageway as part of the AWPR/Balmedie-Tipperty dualling project.
More than £740million of investment from the Scottish Government in the project has been made and it is expected to be completed by the end of the year.
The AWPR project as a whole is expected to be finished in Spring 2018.
Aberdeenshire East MSP Gillian Martin and Richard Thomson, the SNP group leader for the local authority, said they were delighted by the opening of the newly completed carriageway at Foveran on the A90.
Aberdeenshire East MSP Gillian Martin said: “It is fantastic to see some of the first stretch of road has now opened to the public right here in my constituency.
“The construction of the AWPR has been the result of millions of pounds of investment as well as the hard work of hundreds of members of staff across the project.
“The efforts of all involved are now starting to pay off and I look forward to marking many more milestones in the months ahead.”
Aberdeenshire SNP group leader and Ellon & District Councillor Richard Thomson, said: “The construction of the AWPR has been long overdue but is now being delivered to the people of the North-east by the Scottish Government. I am delighted this stretch of road has now been opened and I’m sure motorists will be pleased the project is taking shape.”
Meanwhile, a Transport Scotland spokesperson said: “This new section of road, along with the traffic management measures the contractor will put in place, will bring drivers into close proximity with road workers, so we are strongly encouraging road users to apply more caution than usual when driving through or nearby this section of the A90. Road users should also observe the 50mph speed restriction and road signage to enhance their safety, as well as the safety of others.
“We would like to thank road users for their continued patience and support during the construction of this major infrastructure project.”
