Costain completes A19 Testo’s flyover for Highways England

Costain has completed work on the £130M A19 Testo’s flyover.

The Highways England scheme involved the installation of a 1,393t bridge which will act as a flyover, reducing traffic at the notoriously busy Testo roundabout in South Tyneside.

A 1,000t mobile crane was used to lift the bridge beams into position in the summer before concrete pouring took place on the 142m-long bridge deck.

Drivers can now travel along the A19 over the roundabout and benefit from new slip roads to the A184.

The scheme to improve congestion and reduce journey times for drivers is due to be completed next summer. Costain led on the job, having originally been appointed in 2006 before the upgrade was put on hold by the government in 2010.

Transport minister Baroness Vere of Norbiton said: “The £130M Testo’s junction upgrade will be hugely beneficial to the North East, providing swifter, more reliable free-flowing journeys and supporting economic growth in the region.

“As we build back better from the pandemic, this Government will continue to invest billions of pounds to improve infrastructure, boost connections, and level-up regions right across the country.”

Construction of the Testo’s flyover began in March 2019, in an effort to tackle the heavy traffic which beset the junction, and is predicted to cater as many as 83,400 vehicles every day by 2033.

New link roads are being built between Downhill Lane and Testo’s, aimed at boosting journey times, as well as providing new facilities for pedestrians, cyclists and horse riders.

Highways England acting chief executive Nick Harris added: “This opening is an important milestone in the substantial investment being made in the North East’s major A roads.

“These improvements will make a major contribution to the region, from providing better journeys to and from the region’s ports and Teesside airport, to improving journey times for local people who can get home more quickly and safely to their families or to and from their workplace.

“Our roads are not only the lifeblood of our economy, they support local as well as national businesses, and are vital to enable our emergency services to support local communities.”
