The 43 year-old viaduct, which carries the existing A14 over the railway line and local roads currently dominates the skyline near the Huntingdon train station. Removing it, and creating link roads to and from the old A14, is an important part of the A14 Cambridge to Huntingdon scheme, which is upgrading 21 miles of the A14 to three lanes in each direction, including a brand new bypass south of Huntingdon.
The plans will enable a major redesign of the Huntingdon train station area. A new public transport hub will be created, with bus stops conveniently located for the railway station. Removing the viaduct will also reduce noise and air pollution and will facilitate further improvements in Huntingdon town centre.
Main construction work is expected to start in 2019.
Chris Bayliss, A14 project manager at Highways England, said:
Work to upgrade the A14 between Cambridge and Huntingdon is progressing well and we are on schedule to open the new road to traffic by the end of 2020.
The Huntingdon viaduct was built in 1975, and removing it will create new opportunities for Huntingdon. Once the new A14 is open to traffic, the old A14 will become a local road. The plans we are sharing today will make it even easier for people to travel around, as well as in and out of, Huntingdon.
We are holding six public events this June and encourage people to come see us for a chat and find out more about these exciting plans!
To find out more about the work in Huntingdon people are invited to come along to one of the events - details can be found on the scheme webpage.
The £1.5bn A14 upgrade will add additional capacity, boost the local and national economy and cut up to 20 minutes off journeys.
The main construction work at Huntingdon will include a new Mill Common link road, the removal of the A14 viaduct and work around the train station, and a new Views Common link road. Preparatory work, such as archaeology and utility diversion, will start ahead of main construction work.
The A14 Cambridge to Huntingdon archaeology team is calling for volunteers to take part in a free summer community dig programme between 24 July and 25 August 2018.
This is a once in a lifetime chance for people to take part in one of the largest archaeological excavation projects ever undertaken in Britain.
Volunteers will work alongside archaeology experts from the A14 archaeology team and its contractors MOLA Headland Infrastructure, exploring evidence of industrial activity relating to the abandoned medieval village of Houghton, near Huntingdon, as well as Iron Age and Roman remains.
Each volunteer must be able to commit to five (not necessarily consecutive) days of excavation from 9am to 4pm.
To apply, email firstname.lastname@example.org before 25 June 2018, stating your preferred days.
