Mott’s £6m Plan Approved For Hammersmith Bridge

The title of this post, is the same as that of this article on Construction Index.

This is the introductory paragraph.

Hammersmith & Fulham Council has approved a new plan to stabilise Hammersmith Bridge at significantly below the original expected cost, with works completing in less than a year.

Consulting engineer, Mott MacDonald have developed a solution to the bridge that is simple in the extreme.

This sentence describes the principle at the heart of the solution.

The Mott MacDonald solution involves the use of elastomeric bearings, which allow any pressure to be applied equally to all four corners while protecting the vulnerable 134-year-old cast iron structure.

There would also appear, that some very serious computing has been applied to allow the new bearings to be inserted, by just jacking up the bridge.

In addition to the cost and the speed of installation, the Mott MacDonald plan has been welcomed by Heritage England, will require less closures and doesn’t involve diversion of the gas main.


This intervention will stabilise the bridge and give time for a long-term solution to be developed, that will allow the bridge to be opened to vehicles.

Can We Innovate Our Way Out Of Our Troubles?

One Of London’s biggest problems at the moment is the bridges across the Thames.

This article on the BBC is entitled London’s Bridges ‘Are The Capital’s Embarrassment’  and is typical of many.

Hammersmith Bridge is causing particular trouble and has been closed to all traffic for some time.

But then I saw this innovative solution to the Hammersmith Bridge problem.


  1. Hammersmith Bridge is still closed.
  2. A floating bridge has been added alongside for pedestrians and cyclists.
  3. The floating bridge uses parts of the old Blackfriars pier.
  4. There is an innovative floating pontoon, which is activated by the current, that is used in the middle of the river to transfer passengers across.
  5. New Civil Engineer thinks, the temporary bridge could become a tourist attraction.

The design made me smile.

All Of Scotland Is Now Twinned With Marlow

This article on the BBC, is entitled Winds close Forth Road Bridge and cut power to homes.

At two this morning a truck overturned on the Forth Road Bridge and the bridge has been closed since.

This is the full story from the BBC report.

The lorry on the Forth Road Bridge blew over at about 02:00 GMT. A spokesman for the bridge-operating company said the bridge had been closed to HGVs from 00:30 GMT.

The truck was travelling north from the Edinburgh side towards Fife, but was blown on to the southbound carriageway, damaging a 40-metre stretch of the central grilling, he said.

It had been lifted off the central grilling by a crane by mid-morning, but it could not be completely cleared from the scene until the weather improves.

The bridge remains closed both north and south-bound.

The driver of the lorry has been charged with dangerous driving, police said.

What an idiot!

But there was also the incident on the historic Marlow Bridge over the Thames. This is from Wikipedia.

On 24 September 2016 the bridge suffered ‘potential structural damage’ following an incident where 37-tonne Lithuanian haulage lorry exceeding the weight limit attempted to pass over the bridge. The bridge was closed for two months to allow Buckinghamshire County Council to undertake a series of stress tests on the suspension bridge hangers and pins, together with ultrasound and magnetic particle tests. No significant damage to the bridge was found, and had given the all-clear to reopen the bridge on Friday 25 November following restoration of sections exposed for weld testing with three coats of paint, removal of scaffolding surrounding the bridge’s two towers, and reinstatement of timber work removed for inspection. To the applause of around 100 onlookers, Marlow Bridge was reopened to traffic at 10am on Friday, 25 November.

Consider that Marlow Bridge was built in 1832, it has survived the better part bof two centruries well.

However Marlow Bridge was built by Bristolian; William Tierney Clark, who was also responsible for Hammersmith Bridge on the Thames.

Internationally, Clark was also responsible for the iconic Széchenyi Chain Bridge across the Danube in Budapest.

I took the picture, when I did my Home Run From Budapest in 2013. What you see is not wholly the original, as that was blown up by the Nazis in the Siege of Budapest in 1945.

Incidentally, the engineer who supervised the construction of the bridge from parts sent out from the UK, was the Scot; Adam Clark.

As Adam Clark was born in Edinburgh, I’ve concluded by bringing the narrative back to the Forth Bridge.
