Potential route options (Overview)

The potential route options are presented on this page. There are three options (1, 2 and 3) for the western part of the route, and two options (A and B) for the eastern part. The route alignments presented for the purpose of this public engagement are indicative and will be subject to refinement and further technical assessment following public feedback.

For all options for the western part of the route, transport modelling indicates that the new A46 between the M5 and B4079 would need to be a dual carriageway to cope with future traffic growth. 

For both options for the eastern part of the route, transport modelling indicates that traffic volumes on the eastern section would be lower and that the main part of the new A46 between the B4079 and Teddington Hands would only need to be a single carriageway. 

Further information about the transport modelling undertaken is available in the following document:
