TfL says: "We are supporting Hammersmith & Fulham Council with the repairs. It's likely we will need to completely close the bridge to do this work as quickly and safely as possible.
"The Council has asked us to consider installing a temporary walking and cycling bridge to keep this essential link across the river open. At the moment people are able to walk and cycle across Hammersmith Bridge, many of them heading to and from Tube and bus services at Hammersmith station.
" The temporary bridge we're proposing is a seven metre wide, prefabricated steel structure, supported by two piers in the river.
" The bridge would be step free, with a 5.5 metre-wide surface for people walking and cycling. Access would be by shallow ramps from Queen Caroline Street on the north bank and from close to the junction of Castelnau and Riverview Gardens on the south bank.
"We will need planning permission from both Richmond and H&F Councils to build the temporary bridge.
" We also want to ensure that areas around the landing points of the temporary bridge are fully restored for the benefit of the local community once all the main bridge repair works have been finished and the temporary bridge has been removed."
TfL says it is aware the proposal will attract a range of views and wants to understand them as soon as possible.
