Talks to replace the South Quay footbridge are underway, according to the organisation that looks after it.
Fears were raised after the DLR strike in November , with Canary Wharf councillor Andrew Wood claiming the bridge was too old to be taking so many foot passengers.
The bridge is managed by the Canal and River Trust , which says a study is currently underway to look into replacing it.
A spokesman said: “We currently have responsibility for maintaining the bridge and know that there are calls for it to be improved.
“A feasibility study with various partners is underway and we are looking at all the different options – each one obviously has its own funding or management challenges, so that’s what is being looked into.
“The bridge is OK at the moment, but obviously many more people use it now than when it was built in the 1980s, and many more people will use it in the future. That is why the feasibility study is underway.”
Cllr Wood raised fears about the durability of the bridge in the aftermath of the DLR strike, during which Canary Wharf workers bottle-necked on the bridge while commuting from the Isle of Dogs.
He said: “Tower Hamlets Council has admitted this bridge won’t be fit for purpose by 2021 but you do wonder whether it will last that long, can it withstand that weight of people?
“The bridge itself is half of the old bridge so it does not quite fit the gap which is why it steps down on one side.”
Both Tower Hamlets Council and Canary Wharf Group declined to comment on whether they planned to contribute to a bridge rebuild.
