We held public consultations for phase 1 in December 2017, July 2018 and February 2021.

Following these consultations we made changes to the scheme design, such as moving the road as far away from the Wendover Park and Stoke Grange estates as possible.

In February 2021 we held a phase 2 consultation event, which took place online due to national Covid-19 restrictions. We held an online questions and answers session on 15 February 2021.
