West Sussex County Council has called for an extended public consultation regarding the A27 Chichester Improvement scheme.
Highways England announced it plans to run its public consultation on options for A27 improvements in Chichester over six weeks in the spring.
The County Council has since written to Highways England to ask this length of time is increased to 12 weeks.
In a letter to Highways England, County Council Leader Louise Goldsmith said: “We feel, along with a number of concerned local residents, this is an insufficient period of time to enable the completion of an effective consultation, necessary to substantiate any future decision on the A27 Chichester Improvement scheme.
“We recognise that consideration must be given to the impact on the overall programme of extending the consultation.
“However, to enable the options contained in the consultation to be presented with coherence and clarity, we consider it will be necessary to extend the consultation period beyond the six weeks that are currently planned, particularly as the consultation is likely to take place over the Easter period.”
She added: “This will help to ensure that the options in the consultation are fully understood and that all local stakeholders have sufficient time to provide a comprehensive response to the consultation.”
