The event, held at Hammersmith Town Hall, discussed burying parts of the A4, including the section through central Hammersmith.
Hammersmith & Fulham Council leader Cllr Nicholas Botterill opened the meeting by reinforcing the council’s support for a tunnel. He said: “Let me be absolutely clear. Hammersmith & Fulham Council wants the flyover replaced and we will do everything in our power to make Hammersmith’s tunnel vision a reality.
“Hammersmith flyover is ugly, divisive and hugely costly. This elevated concrete monster has divided our town centre for decades – magnifying traffic noise and polluting our air in the process. It scythes through the heart of our town centre creating a very real barrier that gobbles up space, blocks light, cuts residents and visitors off from the river, and limits business and trade.”
Cllr Botterill explained that the council’s feasibility study to explore the various tunnel options is well underway and aims to answer two main questions – could a tunnel be built and should a tunnel be built?
The study is exploring various tunnel lengths and possible starting and end points, and will measure options against social, economic and environmental benefits. It will include feedback from local residents and will be completed by March 2014 – when the study will be given to Transport for London (TfL) which owns and manages the A4.
Engineering firm CH2M Hill Halcrow is exploring the ground conditions in the area to help answer the question of ‘could a tunnel be built’.
Tom Ryland, from West London Link architects, presented one tunnel option that could stretch from Hogarth roundabout in the west to Earl’s Court in the east. Mr Ryland said a flyunder could, in part, pay for itself by releasing former highway land for development.
