Hammersmith Bridge underside and steelwork – May 2020

The Society’s committee is of the view that as part of the renovation work, there is a great opportunity to improve the Bridge to make it better suited to future needs, requiring more space for pedestrians and cyclists, as mentioned in our last article.  Our proposal is to widen the pathways to allow safe and satisfactory bidirectional walking on one side, and bidirectional cycling on the other, so that cyclists no longer need to compete with road traffic, significantly improving safety.  Currently, because of the somewhat narrow walkways, it’s not possible to safely cycle or even pass easily when walking, certainly not in a wheelchair or buggy.  We think this can be done both at modest cost (certainly compared with the 🔗Garden Bridge!) and largely independently of the planned repair works, so as not to lengthen the closure.  We have a brief update on repair works at the foot of this article.

The bridge’s narrow pathways for most of the span measure approximately 1.6m, widening at the pillars to approximately 1.8m, but still too narrow for bikes to pass safely (one of the reasons cyclists have to dismount currently), let alone to support social distancing needed now, and possibly in the future.  We’ve now looked at the structure in a little detail, and, as shown on the photos here, the pathways are supported by simple cantilevers, apparently bolted on.

Steelwork underneath the bridge was repaired section by section in the 1970’s, and a new grid of substantial longitudinal girders replaced the originals (pierced where bridge hangers meet the deck). Historic photos (right) show the original, very much less substantial steelwork.  Given the scope of the repair works, and amount of money and time to be spent on repairs, there seems little reason not to now consider the attached pathways in more detail, especially if the planned temporary bridge removes the need to keep it open during the works.

TfL is planning a temporary footbridge parallel to Hammersmith Bridge at the request of H&F Council, to assure pedestrian and cycle transit throughout the repair programme.  The aim is to give over the entire Bridge space to the continuing works, with the result that the total closure time could be reduced by 9-12 months.

Hammersmith Temporary Bridge

In an online webinar on 3 April (replacing planned exhibitions which had to be cancelled), representatives of TfL and LBHF set out their scheme for a prefabricated steel structure supported by 2 piers in the riverbed, on the downriver side of Hammersmith bridge. It would be the same height as the Bridge and would have no impact on river traffic.   The usable deck would be 5.5m wide and there will be separation of cyclists and pedestrians (no motorbikes allowed).

Access would be via Queen Caroline Street on the Hammersmith side via gradual ramps. It would take 6-7 months to complete, and planning permission would stipulate it being in place for up to 5 years, with the aim of re-using the structure elsewhere afterwards.

Keeping foot and cycle traffic flowing has to be a welcome initiative. The one downside is that the structure would close the Thames Path on either side, meaning a detour – possibly via the rear of Riverside Studios or past the Apollo and round by Fulham Palace Road on the North side, and via Riverview Gardens on the Barnes side.

Meanwhile the pedestals, hangers, chain bearings and hanger connections are being worked on and acoustic monitoring of the Bridge structure continues. A detailed Scope of Works together with costs is expected later in the spring. The new deck will be steel, with resin on top, which will perform far better than the asphalt over boards which were alarmingly visible previously. The repairs will give 60 years of design life. 

Can we make the restored and repaired bridge work better in the future ?

Summary

In our 30th year of Awards, we renamed our Conservation Award the Tom Ryland Award for Conservation in honour of our past Chairman. We were delighted to present it for the first time to St. Augustine’s Church in Fulham Palace Road.

There were four Nancye Goulden Awards this year, in two distinct pairs, all are projects which have made positive contributions to the Hammersmith streetscape.

The first two are King Street shop fronts: Paintbox Studios and Coffeeology. The other two awards recognise another type of improvement to the streetscape in the form of the Hammersmith Grove Parklets and The Planting under the Flyover.  The wooden spoon went to phase 1 of Sovereign Court.

We were also given a detailed presentation by SSPARC architects covering the history of Olympia and the extensive redevelopment plans, followed by an update from RSHP architects covering the Town Hall redevelopment plans. In a Q&A session, Councillor Wesley Harcourt kindly gave us an impromptu update on the Hammersmith Bridge situation.

Cllr Harcourt describes Hammersmith Bridge problems

At our AGM on 12th June, members of the audience asked a number of questions about the Bridge.

As we reported in our recent newsletter and over the previous 4 years, the bridge has been in trouble for a long time, not helped by a couple of bomb attacks in its history.

Fortunately Councillor Wesley Harcourt (Cabinet Member for the Environment) was in the audience, and offered us an impromptu update on the works to repair it.  He made it clear that the Council is committed to repairing it as a fully working bridge, and that final decisions on the scope of work are yet to made as they depend on the level of funding available from TfL (who want to run double-decker buses), and the Government.  The two key issues appear to be:

1. The level of structural repair, over and above the minimum required to run the original 7.5 Tonne vehicles, is dependent on the funding available.
2. The funding is not yet all in place (principally Government, which as we know is otherwise distracted)

He described the cracks found, and mentioned the details, photos and videos available on the council website here. He also described the effect on traffic on other bridges and roads, notably Chiswick, Putney and to a lesser extent Wandsworth, plus the apparent disappearance of 25% of the bridge traffic, though that may be variability and measurement error. He noted that more environmentally-friendly electric buses actually weigh more due to the batteries, just to add to the mix.

He committed to the council finalising plans and schedule in August, though we have no idea how long the work might take as yet, due to the many variables, and 3 years remains the disappointing figure quoted. We urge the council to embark on the essential repairs as soon as practicable, notwithstanding Government inertia. The outcome of these discussions can’t be resolved soon enough.

Members of the Hammersmith Society, Historic Buildings Group and HAMRA committees met the team in charge of the major works planned for Hammersmith Bridge.

Jane Bain of HAMRA delivered an  impressive visual presentation about the effect of surrounding developments on the Bridge silhouette and general loss of visibility over time, using archive photographs (small selection shown below) to support our contention that the paint treatment of the Bridge should be revisited so the Bridge is visible, distinctive and can be fully appreciated in longer views. The agreement of Historic England will be needed to any change in the colour treatment, which may be a challenge.
