Locals have campaigned for decades for a bypass to be built around the village.
In 2020, NH revealed that about 25,000 vehicles travelled along the A57 through Mottram every day, including more than 2,000 HGVs.
Plans for the scheme were boosted in November 2022 when Transport Minister Huw Merriman granted a development consent order.
However, the Campaign to Protect Rural England (CPRE) sought a judicial review of the plans, claiming the government had failed to consider the environmental impact, alternatives sites and the project’s carbon footprint.
The Local Democracy Reporting Service said that review had now been rejected by the Court of Appeal.
It added that the court’s decision had been “stayed” due to a case regarding another bypass, which had now been resolved.
