The A14 between Histon and Girton in Cambridgeshire is officially completed after numerous delays to the project.
Highways England say the work will help improve journey times on the A14 near Cambridge because of a third lane that's been added in both directions between junctions 31 and 32. There have also been improvements to the westbound access roads to the M11 and A14 at the Girton interchange.
The improvements on the A14 are part of Highways England’s £317m pinch point programme to improve more than 100 congestion hotspots nationwide.
Construction work started in April 2014 and was completed on Sunday 13th September.
