A proposed new bridge, costing up to £41m, to reduce traffic congestion in Great Yarmouth is due to be looked at by Norfolk County Council on Wednesday.
The plans, which are at their early stages, could see the River Yare gaining a third river crossing.
A lifting bridge is being considered to allow boats to pass underneath.
A report to the economic review panel of the council says the new bridge would be used by between 1,400 and 1,800 cars an hour during peak time.
It would also take pressure from the existing Haven Bridge and Breydon Bridge.
Planning officers say in the report that the crossing would "contribute greatly to reducing congestion in the Great Yarmouth area".
They say the construction costs would be between £34m and £41m.
The report says more work is to be carried out by the county council's Planning and Transportation Stretegic Partnership and Great Yarmouth Borough Council are being consulted.
Development work on the project is expected to cost £50,000 per year.
