A decision on whether a second bridge will be built over the River Mersey - linking Runcorn and Widnes - has been postponed by the government.
The bridge could open in 2007 if government funding is approved
It was expected on Tuesday, but it will now be at least two months before the £250m Mersey Gateway plan is decided.
Halton Council wants to relieve pressure on the Runcorn Bridge.
Ministers say they need to know more about how the local environment will be protected in particular the river and its surroundings.
It is thought the plan will be agreed but with part of the cost being financed by tolls.
Halton Council had hoped that the bridge would be approved before the general election.
A spokesperson for the Mersey Tunnels Users Association (part of the National Alliance Against Tolls) said that another road crossing was "long overdue".
