A19 Tees Flyover to closed off to traffic over four full weekends to allow for repairs
A busy section of the A19 is to be closed to motorists for four full weekends as essential work is carried out to repair aging joints.
Drivers have been warned to plan ahead for the closures, which will take place next month and into April.
Highways England has said it needs to carry out vital work on the section of road, which carries thousands of vehicles every hour.
The crossing is 45-years-old this year and because the joints on the viaduct are coming to the end of their useable life, they need to be replaced.
The layout of the road and nature of the work means it can only be carried out safely if one of the A19 carriageways is closed.
By shutting the road fully in one direction, engineers say they can work around the clock to complete the job as quickly as possible.
The closures are:
*Friday, March 6, from 9pm to Monday, March 9 at 6am – northbound closure
*Friday, March 20, to Monday, March 23, at 6am – southbound closure
*Friday, March 27, to Monday, March 30, at 6am – southbound closure
*Friday, March 17, to Monday, April 20 – northbound closure
Senior project manager Ben Dobson said: “We understand a weekend closure will cause disruption, so we’re letting people know in advance so people can start planning their journeys.
“Safety is our top priority and it’s crucial we take measures to stop the structure deteriorating to a point that it could become a safety issue.
“We’ve worked closely with Stockton Borough Council and Middlesbrough Council to arrange diversion routes and ensure drivers see advance warning signs and have talked to local organisations about our plans.”
The main northbound diversion is the A66 eastbound to A66/A1032 (Cannon Park), Newport Bridge and rejoining the A19 at A1046 (Haverton Hill/Portrack).
The southbound diversion is the reverse of the northbound closure.
Traffic is likely to be busiest between 10am and 6pm on the Saturdays and Sundays, so Highways England advises drivers to allow plenty of time for their journeys.
