A route for a controversial new bypass is due to be recommended on Tuesday.
Many people oppose some or all of the possible ring road routes
Norfolk County Council is to reveal its favoured route for a ring road north of Norwich to councillors.
There are three possible routes to link the city's eastern end with its airport in the north and six possibilities to complete the circle to the west.
But there is widespread opposition to several of the proposed routes and most leading environmental organisations have condemned all suggested routes.
Norwich already has a southern bypass and one aim of completing a ring road with one to the north is to relieve the city's congested inner ring road which is often clogged with traffic.
The city's inner ring road is often clogged with traffic
The decision over a preferred route for the Northern Distributor Route (NDR) was put back in February because the council cabinet felt the impact on the environment and traffic needed further research.
The need for a NDR road has been included as a regional priority in the draft East of England Plan.
About 78% of local residents have supported the relief road in principle, according to consultations by Norfolk County Council.
