The supermarket chain struck a deal to build on land previously used for horsebox parking and construction is now underway at the location off West Dyke Road after planning permission was granted.
Libby Jones, who has lived in nearby Easson Road for 46 years, said highways changes meant a filter lane – used by traffic to turn right into the cul-de-sac – would be reduced in length to just one vehicle.
This was to accommodate the extension of another filter lane in the opposite direction which will be used by shoppers to turn right into an entrance road for the new store.
This had led residents to fear it could eventually be removed altogether, although Redcar and Cleveland Council said there were no plans to do so.
Mrs Jones said: “Lidl have been allowed to dictate the road markings, not just at the entrance to the proposed store but further along the main highway. West Dyke Road has always been busy with traffic, but in the last 40 years it has doubled.
“You also have traffic queues going into the car boot sale [held on the racecourse] and traffic coming in and out of Tesco.
