A cyclist who uses the Greenwich Foot Tunnel to commute to work in Canada Water has set up an app that allows people to see whether its often faulty lifts are operational.
Software engineer Andreas Nikolaou said he came up with the idea after he saw some tunnel users struggle to climb the stairs on either side of the river when the lifts were out of action.
He added that climbing either the 100 steps on the south side or the 87 steps to the north can be a problem for people with mobility issues.
Mr Nikolaou said he started using the tunnel because it is one of the few ways to cross the Thames in south-east London for free.
Mr Nikolaou said: "It doesn't feel as accessible as when you are in central or west London where there's a bridge like every kilometre.
