Croydon Council, Network Rail and Menta Regeneration have restated their commitment to the project.
It follows a meeting with concerned residents regarding the completion of the public walkway over the station.
Network Rail announced in 2013 that it was to invest more than £20m into the development of an east to west over platform foot bridge.
Croydon Council has contributed around £6million and Menta has committed £15million.
The council says a timetable of how and when the bridge will be completed is now being developed.
