Important news about the Iron Bridge!

KWAG fully supports a morning event this Sunday to bring about new attention for the plight of the Grade II Listed Iron Bridge on the estate.Frustrated locals in north Bristol are marking 800 days since a vital – and historic – footbridge was closed to pedestrians by Bristol City Council, with a public rally showing how much the bridge is loved.

Kingsweston iron bridge is a Grade II listed cast iron structure, built circa 1820 by legendary roads engineer John Loudon McAdam (who gave his name to tarmac). It forms the only safe pedestrian link between the Blaise and Kings Weston estates in north Bristol. It was used daily by hundreds of dog walkers, families, schoolchildren and ramblers until it was struck by a high-sided lorry on 4 November 2015. The bridge was swiftly scaffolded by Bristol City Council and closed to pedestrians – and has now remained this way for over 2 years and 2 months. This week marks 800 days since the bridge was last open to foot traffic.

The last planting beds on the garden front of Kings Weston have recently been completed by Norman Routledge and his team at the house. Focus is now turning to the main front of the house facing the Home Park. Plans are being drawn up by the house to look at creating a new formal forecourt in front of the main steps.

The new formal area is intended to reflect the original Great Court that once lay in a similar area. Although smaller in size it is intended that the design will use the same classical proportions.

Work on designs is likely to continue over winter and a Planning and Listed building application will follow. The illustrations here are to help everyone get an idea of the character of the proposals and get feedback on them to help Norman and his architect, Quentin Alder, develop designs that respond to people’s thoughts.

If you have any suggestions, ideas, or concerns please forward them to us so we can coordinate a response to Norman. Unless you ask otherwise we will keep any feedback anonymous. Please email us at kwactiongroup@gmail.com, call 07811 666671, or post your comments to us as soon as possible, or before 1^st January 2018.

Many in Shirehampton will know about the lamentable destruction of the former National School in the village centre a few years ago, well some interesting things have arisen since the loss that might start to outweigh the loss of the historic building. Last year Avon Archaeology undertook an excavation on the site and made some exceptional finds; the first significant Roman material found in Shirehampton beneath the Victorian foundations.

Some of the pottery dating mainly from the 3rd to 4th Centuries.

As well as some fascinating individual finds including two fibulae brooch and a good quantity of pottery The dig identified a strong linear ditch feature into which much of the material had been deposited. This ditch, and an associated stone scatter along one side, support a new assessment of the Roman impact on the Kings Weston estate.

Linear ridges and shallow impressions crossing north-east – south-west across the meadowland of the Home Park have long puzzled us and our archaeological geophys surveys have not yet reached the most visually prominent areas to asses them. In association with our existing knowledge there is more exciting potential in these features.

To the south of Kings Weston was the town of Abona, on the Avon at modern Sea Mills. Roman Roads can be tracked southwards and across Durdham Downs heading for Bath, and a major connection to Gloucester is known. It is significant that the known course of this road passes to the north side of the Kings Weston Ridge, continuing a line from Cribbs Causeway through Henbury. However, if that line is projected onwards it is not to Sea Mills that it heads, but directly through the Kings Weston Parkland to the old ferry across the Avon to Pill and the Somerset side of the Avon.

The recent finds in Shirehampton now give greater weight to the route of the road passing across the Home Park, Down Park Hill, then heading towards the banks of the Avon at Lamplighter’s along the modern course of Station Road; From there significant settlements at Gatcombe, Charterhouse on Mendip, and Ilchester would have been directly connected with Gloucester.

A review of the archaeological record for the road from Bath towards Abonae also suggests that that road too bypassed the settlement proper and headed across the river Trym in a characteristically straight line, and crossed Kings Weston Hill at the Old Inn, and by way of a zig-zag known to have existed before the 1730s.

What this means for Kings Weston is significant. The conjectural new alignments give great potential for undisturbed Roman material being located within the flat land around the Home Park, and close to a major junction in Roman Roads. The nature of that junction, the foundation of the medieval manor at Kings Weston, and the efforts made by the Southwell families and those before them to divert the road outside their park might now be explored within this new hypothesis.

Some long-awaited progress to report from Bristol City Council regarding their repairs on the Regency iron bridge over Kings Weston Lane. This is the full text of the highway teams report:

Kingsweston Lane Footbridge was impacted by a HGV on the 4th November 2015, where substantial structural damage was suffered to the underside of this lightweight footbridge cast iron structure. There is already low headroom warning signage in place on approaches to this footbridge. The footbridge was immediately inspected on the same date and was subsequently closed to pedestrians on health and safety grounds.

As a consequence of the damage incurred the Council installed a temporary scaffolding bridge support arrangement above this footbridge to prevent the bridge itself from collapsing onto Kingsweston Road below. This support scaffolding was installed using an emergency road closure on the 5th and 6th of November 2015. The bridge remains closed to pedestrians. A signed alternative pedestrian route via Kingsweston Lane (including a temporary pedestrian crossing), is in now place. The road remains open to traffic. The alternative pedestrian route is inspected on a monthly basis

The Council is committed to reconstructing this listed historical footbridge and to reinstall this vital pedestrian link. However due to the listed status of the bridge and the paucity of existing information, further detailed investigation will be required to be undertaken before BCC are in a position to commence works on site. Subject obtaining the appropriate Capital Investment availability, this is provisionally programmed to be commenced on site early in the New Financial year, April 2018.

By potentially raising the headroom height of the footbridge it is hoped the mitigate the future potential for HGV bridge strikes, However this would change the appearance and would create pedestrian ramping on the approaches to the footbridge which may not be accepted by (HE) or BCC Planners. This will be investigated further by BCC and a decision made on the appropriate design accordingly.

The footbridge itself is constructed from numerous jointed cast iron elements and is also grade 2 listed, constructed circa 1800. The footbridge has received significant structural damage with the east side of the bridge sustaining major damage and loss to two arch beams which transfer the structural loadings of the bridge to the walled abutments on either side. These are the key structural members that hold the bridge in place and give it the required strength. To date we have luckily been able to find the old wooden moulds for these arch beams and have been able to source an suitable boundary and have had a replacement arch beam already recast and this is now in safe BCC storage awaiting to be installed.

We intend to use our Professional Frameworks Consultants (CH2M) to undertake the preliminary investigations, site surveys, Listed consent submission, detailed design/assessment, and Contract preparation and Tendering out to Market. The likely cost of this this commission brief would be in the region of £30,000.00 to include and cover the following phases:

Preliminary Design and Investigation Programme For Kingsweston Lane Footbridge

Phase 1: Preliminary Date: October 2017 
Undertake a full topographical survey of the bridge itself and the surrounding area of the bridge (15m either side). This will be done under a full road closure, organised by BCC. As this is a Conservation area we will need to consider the flora and fauna within the surrounding area , including bats and badgers etc.

Phase 2: Preliminary Date: November 2017
Inspect Bridge and determine the original method of original construction and connection. This will determine how the bridge is to be dismantled taken down, stored and then resembled. Undertake structural investigation and assessment as to the possibility of raising the bridge by about 400mm and look at the feasibility of this and the overall impact this would have in terms of access across the footbridge ect.

Phase 3: Preliminary Date: December 2017 
Liaise with David Martyn (BCC Historic Environment/Conservation Officer) on Listed requirements from Historic England (HE) for the dismantling, storage and re erection of the bridge. Consult with HE & Planning with regard to consents required to raise the footbridge if this is considered to be feasible.

Phase 4: Preliminary Date: January 2018
Submit required Listed Consent to HE and BCC Planning BCC and await outcome and further instruction.
Phase 5: Preliminary Dates: February to March 2018
Detailed Design, Contract and drawing Preparation, Tendering out to Market, Assessment of returns and award of Contract.

A regular complaint is that there are so few benches around the estate to rest or enjoy the parkland. We’d like to remedy that and hope that you will be able to help us. With the agreement of the Council we’ve identified a series of locations around the estate where they could be installed, and we are asking for sponsorship for simple oak benches.

Our intention is that people can select a location and sponsor a bench as a, gift, memorial, or simply as a generous gesture. KWAG volunteers will procure heavy duty oak benches and install them on your behalf. If you would like a small brass plaque on your bench these can be supplied at extra cost.

This map will show you the agreed bench locations. https://drive.google.com/open?id=1uBosa4CK0btlH_JFb_bB3jvTVZ0&usp=sharing We regret that locations can only be offered on a first-come first-served basis.

The solid oak benches are available to sponsor for £190 or £230 with a personalised memorial plaque. Payment can be made via Paypal and the location, and any further details included in the “Add special instructions” box, or get in touch with us by email at kwactiongroup@gmail.com or call 07811 666671 to reserve a location and find out alternative methods of payment.

KWAG has already committed to providing two benches and we hope to install these soon. You will also notice that one location has already been reserved. This spot, overlooking the Home Park and the house, will be the location of an artwork as part of the Forgotten Landscape project, and will be designed by Debborah Aguirre Jones. The bench will be a unique design incorporating elements of just three locations across the whole Lower Severn Vale project area. Each bench will then have a texture or pattern burnt into the wood

Robert Mylne is a significant, but less well known, figure of Eighteenth Century architecture. Long overshadowed by his contemporary and fellow Scotsman, Robert Adam, he was no less skilled as a designer. He studied extensively in Rome under the architect Giovanni Battista Piranesi, and when he returned to England in 1759 he quickly entered, and won, a competition for a new bridge at Blackfriars, London, one of the most prestigious and high profile projects of the age.

A recent research visit to the collections of the Royal Institute of British Architects at the V&A has brought new depth to our understanding of what the two men achieved at Kings Weston. Although Mylne’s diaries have been published before there have been many significant omissions.

We now know that Mylne first arrived at Kings Weston, at Southwell’s invite, On April 30^th 1763. He stayed for eleven days, during which time he no doubt he discussed his client’s ambitions at length, and made initial surveys and proposals for the house and grounds. He returned to London with Southwell and began work.

First amongst Mylne’s works were the walled garden and stables. The following year he moved onto the house itself and the interiors; The Eating parlour, Drawing Room, the building of the bay window overlooking the Severn, and the Saloon (picture gallery) and other interiors were all tackled over the following five years.

Amongst the inexplicably overlooked diary entries is one that now confirms the stone pedestal in the Echo as Mylne’s work. On March 20th 1766 he wrote “Made out a drawing for a pedestal to a statue for Mr Southwell and ditto at large. To be charged by the workman’s bill.” The following day, no doubt with the instruction of his client Mylne ordered the pedestal to be executed.

The statue is believed to have been collected by Southwell on his Continental tour, but Mylne’s pedestal is a work of art in its own right. Carved from a single piece of Portland Stone the design illustrates the architect’s knowledge of the latest understanding of classical architecture. The round cylinder-shaped pedestal takes the form of an ancient Greek altars. Carved in high relief on the simple drum are swags of leaves draped from simple rosettes; oak leaves are associated with the highest gods in the Greek pantheon, but also have a more general sacred symbolism.

Our recent trip has also identified regular payments made by Southwell for Mylne’s work. During the most active periods Southwell was paying £100 per annum to his architect. Between 1764 and 1770 payments in excess of £450 were transferred to Mylne, a figure excluding the cost of many other individual drawings considered extra to their original agreement. These substantial sums perhaps reflect the skill of the architect, and responsibility of his position; the annual wage of Southwell’s senior footman was just £16 16s a year.
