The A1032 across Newport Bridge is due to reopen to vehicles on Wednesday (October 29).
A large tunnel style scaffold is under construction which will enable motorists to use the road while the remaining repairs and repainting take place.
Stockton Council’s Cabinet Member for Regeneration and Transport, Councillor Mike Smith, said: “We had hoped to reopen the bridge on Monday but that was weather dependent and despite the contractors working round the clock, the very high winds we’ve had in the last few days have made it unsafe to progress the scaffold as quickly as we’d have liked.
“It’s unfortunate that we’ve lost this time but the forecasts are not indicating weather that should cause any further delays and contractors are working flat out so the bridge can open with two lanes in each direction from Wednesday. We know the works have caused a lot of frustration and look forward to the congestion easing once the bridge reopens.”
The repainting of the 80-year-old Grade II listed structure began following the completion of a deep clean of more than 50,000 square metres of metal.
But the cleaning process revealed further areas of corrosion and damage in need of extensive repairs.
The discovery prompted Stockton Council to revise the programme to incorporate the scaffold tunnel.
There will be a 17.5 tonne weight limit throughout the works – this will prevent use by some heavy goods vehicles but buses will be unaffected.
Access for cyclists and pedestrians will be maintained throughout.
