Residents living near the proposed new £135m Castleford Tigers stadium development fear increased traffic coming to the site could put lives at risk.
Householders on Stainburn Avenue – next to the proposed site off junction 32 of the M62 - say traffic in the area is already heavy and the development will make it worse.
Resident Peter Taylor, 65, said: “The traffic is bad enough as it is now, without this development.
“My main fear is for the emergency services. They struggle to get through from Pontefract, so if these plans go ahead, it could be the difference between life and death.”
Residents also fear there will not be enough parking for visitors to the new development and drivers will park outside their homes.
Mr Taylor, who has lived on Stainburn Avenue for two years, said: “It’s a lovely street but if this development goes ahead I’m worried it could devalue my house.”
Lateral Property Group’s proposed development includes the 10,000 capacity stadium, a food store, petrol station, shops and a country park.
It would create up to 2,000 new jobs plus hundreds more during the construction phase.
The development, off junction 32 of the M62, would be on land between Stainburn Avenue and Spittal Hardwick Lane.
Philip Lunn, managing director of Lateral Property Group, said: “We have had detailed discussions with the Highways Agency and the local highways authority.
“We are working on proposals which will bring significant investment to improve and futureproof the local highways network.”
