St Anne’s Footbridge – Extended Closure

bridge1

St Anne’s Footbridge linking Crews Hole to the shopping area in St Anne’s has been closed since the beginning of June for major repairs.

When the old concrete bridge deck was removed it revealed significant corrosion to the bridge steelwork which required repair before it can be painted and the new deck installed (see photos below). This has led to the originally estimated period of 12 weeks for the work being extended.

Work is continuing while the bridge is open.  Scaffolding will start to be removed on Monday 11th January.   The bridge will be kept open while the scaffolding is being removed but there will be a banksman at either end of the bridge to allow the scaffolders to work safely and guide members of the public across.

The bridge should be open before Christmas provided there are sufficient breaks in the rain next week. Work will focus on the main bridge span painting, so that the scaffold can then be removed and the bridge re-opened as soon as possible. The painting of the steelwork on the ramps will be completed next year but this can be done while the bridge remains open.

The current programme is as follows, weather permitting:

Ongoing – 11th December – final fit of deck sections and painting of main span,
12th – 23rd December – removal of scaffolding,
14th – 18th December – preparation and painting of ramps, completion of painting of main span,
Before Christmas – bridge opens to public,
After Christmas – completion of painting of ramps, bridge remaining open.

Bristol City Council regret the current inconvenience to local residents.

Updated 7 November 2015

The Council now expect works to be complete and the bridge reopened by early – mid December.

The repairs and welds that had to be carried out before the deck could be re-laid are now finished and the majority of the deck replacement is now complete.

The next phase is due to commence on Monday, which will be undertaken by a separate contractor and will entail the preparation and repainting of the ramp on the St. Anne’s side and the upper parts of the main bridge structure. This has not corroded like the lower beams had and so will be a relatively quick job. Due to the likely variability of the weather at this time of year we cannot commit to a firm opening date.

Bristol City Council do apologise for the extension to the works.

Updated 8 October 2015

It is estimated that the refurbishment works on St. Anne’s footbridge will be complete by early November 2015.

Progress to date is as follows:
– The ramp on the Crew’s Hole Road end is repaired, new deck fitted and repainted except for the parapets and columns,
– The main refurbishment works across the main span are nearly complete. This includes steel preparation, removal of all corrosion, removal of redundant steel members, fitting and welding of supplementary strengthening steel members,
– The steelwork of the lower part of the main span is currently receiving its primer coat of paint,
– The new deck across the main span is currently being trial fitted prior to final painting of the lower steelwork.

The work which is yet to be undertaken includes:
– Completion of trial fit of deck across the main span,
– Completion of painting of the steelwork of the lower part of the main span,
– Final fit of new deck across the main span once repainted,

Preparation of the steelwork of the remaining parts of the Crew’s Hole Road ramp, St. Anne’s side ramp and upper steelwork of the main span and repainting. This will be undertaken by a separate contractor who is programmed to start 19th October 2015 and will work concurrently with the Principal Contractor who is currently on site. Progress of painting works is very dependent upon weather conditions.

Bristol City Council apologises for any inconvenience caused by the delay during these complex structural improvements.

We could only assess the extent of the work required once the whole of the deck had been removed. The contractor is being very thorough in the steel preparation in order to ensure that the final repair is long-lasting and we had underestimated the time required in order to achieve this result.

The current estimate is that the bridge will need to remain closed until the end of October (weather permitting).

• 2nd – 19th June – Erection of scaffolding around entire bridge,
• 8th June – 3rd July – Works on Crew’s Hole Road approach ramp including deck removal, preparation and assessment of corroded steel, test fit of new deck, fabrication of new steelwork for deck support, 3-part paint system to steel members.
• 6th July to date – Removal of deck from main bridge span, preparation and assessment of corroded steel (see photographs below), undertake repair works to steel members.

Planned programme for the coming weeks
• Ongoing – 21st August – Continue preparation of corroded steel to clean finish, continue assessment of steel condition, calculations and assessment of repair methods, removal of redundant steel members from bridge structure,
• Ongoing – 28th August Continue repair of corroded steel members,
• September – Test fit of new decking,
• September – Apply 3-part paint system to lower steel members,

While the bridge is closed pedestrians & cyclists can continue along the river path on either side of the river and cross at Netham.
