Tonight will see the start of the work to lift the 1,393-tonne structure into place before it is then connected up to sliproads on the A184 Newcastle Road, helping to the take an increase in traffic using the interchange once the International Automotive Manufacturing Park (IAMP) is built next to Nissan, with improvements also on the way for the junction at Downhill Lane.

A new flyover will be built at the A19 junction in Boldon so that traffic will not need to leave the major route to negotiate the junction.

The flyover will made up of 25-paired girders, the largest 33 metres in length, with the heaviest pair to weigh-in at around 60 tonne, with a 1,000-tonne crane being drafted in do the work.

Diversions will be in place, with northbound traffic to use the A1231 Sunderland Highway, A195, A194(M) and A194 Leam Lane, and the reverse route will be available for southbound traffic.

There will be alternatives for non-motorway traffic.

Highways England project manager Liam Quirk said the bridge work was an “exciting new phase in the project” which has already seen supporting walls built ready to take the flyover.
