Plans which could help put Cornish football into the big time with a new £12m stadium are being criticised.
If approved the stadium could host a variety of other events
Some residents who live near the proposed site at Treyew Road in Truro claim the location is wrong and the roads could not cope with the traffic.
The ambitious plans go on display at Truro City FC on Wednesday.
But the promoters behind the planned 16,000-seat stadium insist the scheme is getting countywide support and have claimed the city will also benefit.
Truro City FC currently plays in the South West League - several rungs below the Nationwide Conference.
A big game for the team will normally attract a crowd of about 100 spectators. But if the team make it to the Nationwide, numbers could average up to 3,000.
But it is believed the stadium could be a joint venture with the Cornish Pirates RFC, who play in National League One.
The Pirates are realistic contenders for promotion to the Premier League. They have an average crowd of about 1,500, which if promotion is won, could rise to a potential of 10,000.
Michael Eathorne-Gibbons, who runs a guest house opposite the football club, says he is worried about the proposed development.
He said: "I do believe the concept is right, but it's in the wrong place.
"Together with the Pirates rugby, who I believe are planning to move to Truro, you could build a superb stadium with joint facilities and I think it would help to pay for park-and-ride - which Truro surely needs."
Another local resident, Mike Pickering, said cars pouring from the proposed stadium could create gridlock on Treyew Road, causing misery to local people.
But Justin Dodge, one of the directors at Truro City Football Club and one of the architects of the plan, said the plan already has a lot of support.
He said: "The idea of providing a facility like this for Cornwall is an exciting one in most people's eyes.
"They see the opportunity of someone spending this amount of money and investing.
"With the Pirates it's not just football fans, it's rugby fans and sports fans generally. It's fans of music because it will provide a venue for concerts."
The football and the rugby clubs are both ambitious and the planned stadium is being looked on favourably by the local council, although planning permission still has to approved.
It is believed the stadium will be privately funded, possibly with some cash from sports or lottery grants.
Plans for the stadium include car parking facilities, a new hotel and a park-and-ride scheme.
