Hammersmith Bridge engineering challenges and early solutions

An article in New Civil Engineer summarises rather well the challenges and timeline of fixing Hammersmith Bridge.

From the article:

Returning Hammersmith Bridge to its former glory will be a “huge feat of engineering”, according to the Hammersmith Bridge Taskforce’s project manager Dana Skelly.

Skelly and DfT engineering director David Coles outlined the engineering challenges of repairing the bridge during a public meeting.

Challenges include replacing the bridge’s 172 hangers, replacing the seized bearings on all four pedestals on both towers as well as installing external frames to allow the cracked pedestals to be by-passed providing temporary stabilisation to the bridge structure.

Coles said that “17 major defective elements need addressing before the bridge can be fully opened”.

The repair plan has been split into three phases, and it is estimated to take six and a half years to fully reopen the bridge to vehicles.

Fingers crossed, we can look forward to walking and cycling across the bridge by next summer. It will take around 6½ years to strengthen it enough to allow cars back over it, by which time (hopefully):

  • the money will run out, or
  • we will all have got used to not driving over the bridge, so why create a new route for cars, or
  • people will realise that it would be crazy to allow cars to start pounding the bridge again.
