A bridge project in northern Scotland originally expected to cost £18M and be finished in 2015 will now cost £22.3M and take until late May this year.
Aberdeen City Council agreed a further eight-week extension for the Third Don Crossing project with contractor Balfour Beatty.
The scheme – which started in August 2014 – involves building a 90m-span steel box girder bridge over the River Don as well as a smaller structure over the Mill Lade in Grandholm Village, and various road works.
The latest extension was agreed due to problems with weather, re-routing underground utilities and “unforeseen circumstances”.
Aberdeen City Council infrastructure convener Neil Cooney said: “This is Aberdeen’s largest major new bridge infrastructure since the construction of the Queen Elizabeth Bridge 30 years ago and projects of this size are technically complex.
“While we recognise how frustrating these delays are for people, it must be remembered this is a major project which includes two bridges, creating a new road, re-alignment of existing roads, creating cycle paths, and pavements.”
He added: “Once the bridge is open, people on both sides of the River Don will see a tremendous difference getting around the city.”
Balfour Beatty managing director George Hood said: “We continue to support Aberdeen City Council in order to ensure all works are completed as quickly as possible.
“Once complete, the Third Don Crossing will play a significant role in improving local transportation routes. All other works continue to progress at a good rate.”
