Work on Aberdeen’s bypass has resumed after pollution fears saw it halted for a week.
The major development was put on hold for seven days while officers from the Scotland’s Environment Protection Agency (SEPA) inspected the route following floods on the site.
Aberdeen Roads Limited, the contractors behind the new road, voluntarily stopped work in a bid to improve the mitigation measures in place.
But now work has started again.
A Transport Scotland spokesman said: “Construction works on the Aberdeen Western Peripheral Route /Balmedie-Tipperty (AWPR/B-T) project have now recommenced.
“The contractor has agreed a comprehensive programme of remedial works with SEPA, some of which are expected to be completed within a few days and others which will continue in the coming weeks.
“The contractor for the AWPR/B-T project, Aberdeen Roads Limited, voluntarily stopped its construction works to focus its efforts on improving the mitigation measures in place.
“Throughout this process, the contractor has remained in regular dialogue with SEPA and will remain in regular dialogue with SEPA while the remedial works are undertaken.
“We take our environmental responsibilities seriously and will also continue to work with the contractor to ensure that watercourses are protected across the site.”
