Windsor residents who live near Dorney Lake are campaigning to keep a temporary bridge which will give access to the Olympic venue in 2012.
Games organisers want to provide a temporary pedestrian bridge for spectators crossing the Thames from the racecourse to Dorney Lake.
They also propose to reduce traffic by using the racecourse as a transport hub for spectators.
Windsor Councillor John Fido said the bridge was unlikely to stay.
He said: "They're not even going to keep the bridge up for the Paralympics. The reason the present site was chosen was that it was the only feasible site for the bridge to go over because the river (Thames) is quite narrow.
"The only access would be through the racecourse, so it wouldn't be very practical for it to stay.
Windsor resident Gilaine Young said: "I think it would be quite useful to have a temporary bridge from this area, because I like to walk and cycle around this area.
Ms Young said the bridge would mean it would take her only 15 minutes to get to Dorney Lake from her home, as opposed to 40 minutes at present.
Residents have until Tuesday, 31 August to view and comment on the plans for 2012 at Dorney Lake by going online at www.london2012.com/etondorneyconsultation.
The London Organising Committee of the Olympic Games and Paralympic Games (LOCOG) will then apply to South Bucks District Council, Buckinghamshire County Council and the Royal Borough of Windsor and Maidenhead for planning permission.
