Foster & Partners / Delancey temporary bridge proposal

Bridge proposal

We were surprised and excited in equal measure to see a radical new proposal published by the council, in partnership with Foster and Partners and Sir John Ritblat of Delancey, the company now owning the Earls Court development site.  This is designed to temporarily solve the conundrum of getting across the river while the original bridge is repaired.  Details can be read on the council’s website, there’s obviously more detailed work needed to bring it to fruition.

Key points are:

• Raised temporary deck envisages crossing for vehicles, pedestrians and cyclists on 2 levels.
• The deck would overlay and rest on the footings of the existing bridge.
• River traffic could pass underneath.
• Costs believed lower and timescale significantly faster than previous plans.
• Partial dismantling and offsite refurbishment of the existing structure while temporary structure in place.
• Transport Secretary given outline brief by H&F Council Leader on 25th November.

There’s been generally positive comment in the press and social media, and we were particularly pleased to see our favoured approach of offsite construction/restoration being embraced, which should improve the quality of the end result.

Funding

Since the public Task Force meeting in October, there have been snippets of gossip from behind the scenes, but little significant  progress to report. TfL have been instructed to pay for a temporary ferry river crossing, and to contribute £4M towards the bridge stabilising work, drawing from their recent £1.8B government emergency funding.

Central government has now promised to fund the project, conditional on a substantial contribution from the local authority.  LBHF report that funds are not available to meet this demand.  The Hammersmith Society and others are pressing the government to take the long view, and release the Bridge funds now, and negotiate separately with the local authority,  and this is set out in our letters to the Task Force chairman and the Secretary of State for Transport, as previously published.

Enquiries to LBHF and other parties have revealed some further context to the funding problem.  We understand that Hammersmith became involuntary owners of the Bridge in 1985, when the government abolished the GLC (Greater London Council); there is no record of a condition audit taking place at the time, and no maintenance arrangement accompanying the gift, which was perhaps a mistake.

In normal circumstances structural repairs to the bridges over the Thames have been paid for by TfL, with costs of a fraction of the c. £150M budget for Hammersmith Bridge;  this very substantial cost arises largely from the design of the structure with cast iron, and design restrictions on the repair methods imposed by Historic England Grade ll* listing status. 

Over the last five years it appears that LBHF have spent around £5M on bridge maintenance, and a further £2.7M this year on safety monitoring. For comparison, the comprehensive refurbishment and structural repairs to Wandsworth Bridge, have been carried out against a budget of only £6M this year.

Seen in this context, the government demands from the borough appear misplaced. LBHF finances have had no cause to make provision for such costs in their budget, and the cost should surely be carried by TfL , extending the TfL  government support grant as required.
