MOTORISTS face traffic misery when work starts on Monday on an extension to the Beaconside business park.
Temporary traffic lights will be installed and lane closures will take place as part of work to build a roundabout at the junction of the A518 with Blackheath Lane.
Work is expected to last until April or May but highways chiefs say it will improve the infrastructure in the area.
The scheme was given a £1.7 million government funding boost in May and aims to ease congestion.
The new 50-acre site could create up to 2,000 jobs.
