Work on a £11 million ‘hamburger roundabout’ improving links to Didcot with the A34 at the Milton Interchange is due to finish on Sunday, May 8.
Oxfordshire County Council’s 16-month project to build a road through the centre of the interchange began in January last year to boost the junction’s traffic capacity by 30 per cent.
The works have led to agonising commutes for drivers getting to Milton Park and to and from Didcot at peak times with 50mph speed limits introduced on the A34 southbound from the Marcham Interchange up until last month, while drivers faced regular tailbacks on the A4130 leading up to the junction.
Rodney Rose, deputy leader of the council said: “I can reveal the works will finish on May 8.
“It’s been an absolutely essential piece of work that has been carried out and I believe it will help deal with the ongoing traffic demand in the Didcot area.”
The works were due to be completed this month.
Cllr Rose stated the delay into May is due to ‘ironing out the finer details’ of the project and to clear the site of the working materials.
He added: “I think the ‘hamburger roundabout’ style works fantastically well and the previous projects at Heyford Hill and in Headington have shown that they were the best option.”
A ‘hamburger roundabout’ is when a road runs through the centre of a roundabout, resembling the shape of hamburger from a bird’s eye view.
Mayor of Didcot Des Healy said the completion of the works will bring a ‘very difficult’ past 16 months to an end for Didcot’s drivers.
He told the Guardian: “It’s lovely news and I’m sure it’s something that a lot of Didcot residents will be very happy to hear.
“It’s been very difficult for the town’s drivers since the work began in terms of getting access to the A34.
“Of course time will tell if it does a good job but you’ve only got to look at the way this kind of roundabout has been implemented in Oxford to know that they’ve worked quite well in the past. It’s a win, win situation for all.”
Oxford’s ‘hamburger roundabouts’ include the Kennington roundabout on the A423 Southern Bypass, which opened in 2014, the Heyford Hill roundabout, which opened in 2011 and the city’s first at Green Road roundabout in Headington, which opened in 2006.
David Nimmo Smith, the county’s cabinet member for transport, said: “The junction works will make it easier and quicker for traffic to get on and off the A34.
“It will make it easier for rush hour traffic to get in and out of the Milton Park estate. Congestion here has hampered business activities.”
It was funded by the Department for Transport, the Oxfordshire Local Enterprise Partnership and the council.
The Guardian also revealed in February council officers are discussing plans to build an extra lane each way on the A4130 from the Milton Interchange to the roundabout at Mendip Heights in Didcot.
In addition to this are plans to build a £35m ‘Science Bridge’ over the A4130, and a Harwell link road between the B4493 and A417.
