Local residents have been told a decision on the proposed bypass will take at least another year.
Alton Towers said they are currently drawing up a "long-term development plan" for the park, and that villagers can expect a decision on the relief road in the next 12 to 18 months.
The latest problem to hit the much-needed development is that the originally estimated cost of £6 million, which Alton Towers would have to fund themselves entirely, has now doubled to £12 million.
Highways chiefs have pledged to re-examine the plans, which would greatly reduce congestion in Alton. The roads in and around the village are narrow country lanes not suited to the volume of traffic which the park attracts during the open season.
A spokesman for the county council said: "We have met with Alton Towers to discuss the prospects for a relief road, and will be looking in more detail at Alton Towers' future plans."
