The proposal could see a tunnel running beneath the existing A4 from the Hogarth roundabout to Earl’s Court with north-south links.

Residents believe the tunnel is the solution to the "Jammersmith" chaos brought to west London by the emergency closure of the Hammersmith Flyover. Other possibilities include building the tunnel without the supporting link roads and a straight replacement of the existing flyover, either with or without the link roads.

Local press reported that many residents spoke out in favour of "burying the flyover".
