A £17million project to ease congestion at a notorious bottleneck roundabout is still at least two months away from completion.
Dualling of the A421 and improvements to Kingston roundabout began in July 2014, and scheduled to finish in time for the start of the new school term on September 7.
But the council says “complications” have caused a delay.
A spokesman said: “The plan was always to complete in summer 2015 as stated on the scheme signs.
“Unfortunately as a result of complications with the utility diversions, the scheme incurred delays and despite the team’s best efforts the scheme will not be completed prior to the new school year beginning.”
Final surfacing and traffic signal testing will be put in place before the end of next month.
However, further roadworks announced this week are set to disrupt drivers until October.
Starting on August 26, resurfacing work will be carried out on 10 roads across Milton Keynes between 9.30am and 4.30pm – taking up to four working days at a time.
This means roads will be closed with diversion routes set up where necessary.
Councillor Matt Clifton, Cabinet member responsible for Transport Strategy, said: “We need to carry out this resurfacing work and we will of course try and keep disruption to a minimum, but we would ask drivers to be patient, as in the long run, they will benefit from better road conditions.”
The council’s highways contractor Ringway have warned that the dates outlined for works could change depending on weather and other “unforeseen circumstances”.
Information boards on the roadside will give an indication of any changes to the start or finish dates for each scheme. For the full list visit www.miltonkeynes.co.uk
