The long-awaited scheme involves upgrading 21 miles of the heavily-congested route between Huntingdon and Cambridge, including a new stretch of bypass to the south of Huntingdon. Highways England said the new bridge across the railway and river at Offord was continuing to progress well. Construction on the bridge started about as year-and-a-half ago, both abutments have been completed, 72 foundation piles have been put in and the 17 steel beams for the bridge span are in place. Structural work is expected to finish by the end of the year and it will be used by construction vehicles before being surfaced in time for the road opening in 2020. Eight million out of 10 million cubic metres of soil have been moved for the overall scheme, four bridges have opened and some of the new junctions are clearly visible.
