Transport bosses on Teesside have apologised to motorists ahead of major disruption to roads during a major regeneration project.
The development will change the face of Stockton's riverside
The £300m project will change the face of Stockton's North Shore area, with a mix of homes, leisure facilities, hotels and offices.
But the scheme will give travel headaches to commuters in Stockton for 65 weeks from February.
Project organisers say road closures and diversion are unavoidable.
It is expected that the scheme will generate about 2,500 jobs by the time it is completed in 2014.
Work is due to start on the 56-acre site in 2006.
A spokesman for Stockton Borough Council, which, along with Tees Valley Regeneration, is behind the project, said disruption was regrettable, but necessary.
He said: "While the scheme has been designed to minimise disruption, the works are now at a stage where temporary road and lane closures are unavoidable."
From 4 February, the section of road towards Portrack from the Church Road/Maritime Road roundabout as far as the Reg Vardy roundabout will be closed for four months. A diversion has been established.
Traffic lights will control the junction at the west end of Portrack Lane taking traffic onto Maritime Road until work to raise the level of Church Road is complete.
A pedestrian route will be maintained throughout the closure.
