We have now been informed that work to demolish the Burnshot Bridge will take place from 8pm on Friday 24th November, until 5.30am on Monday 27th November.
The A90 will be closed for this entire time, with all traffic being diverted onto the adjacent on- and off-slip roads. Routes for pedestrians and cyclists will not be affected during the works, however bus-stops will be temporarily relocated.
The demolition will be undertaken by a sub-contractor called Beattie Demolition, who are experienced in this type of work having recently demolished the B800 bridge as part of the south approach to the Queensferry Crossing.
Council officials have also organised two information events at Kirkliston Library where representatives from the Council and Contractor will be available to answer any questions from members of the public. The dates for these events are:
- Tuesday 7th November 2.00pm-4.00pm, and
- Wednesday 8th November 5.30pm-7.30pm
These are ‘drop-in’ sessions, so the public can arrive at any time, but there will be no formal presentation or meeting as such.
Here is the full report we received from officials.
A90 Burnshot Bridge
Progress Update No 6
27 October 2017
Introduction
This note provides an update to Progress Update No 5 (attached for ease of reference). This will be the final update prior to demolition of the bridge.
Monthly Inspections
These inspections are ongoing to closely monitor the condition of the bridge soffit. The next inspection is on Wednesday 1st November. Depending on the weather in November, this may be the final inspection prior to demolition.
Structural Health Monitoring
The bridge joints may be prone to damage from freeze-thaw action during November and so Structural Health Monitoring (SHM) equipment will be installed by a specialist contractor on 1st – 2nd November. This will enable the Council’s engineers to remotely monitor the temperature within the joints, and any movement of the central span, in the lead-up to demolition.
Traffic Diversion
Installation of the new semi-permanent signage is almost completed on site, and so much of the temporary signage has now been removed. The pedestrian/cyclist barrier on the Northbound slip road will remain until such time the permanent footpath/cycleway is installed.
Site mobilisation
The Contractor, Balfour Beatty will be starting on site on Monday 30th October. Initial work will be to secure the site with fencing, provision of welfare facilities, installation of site cabins and some further site clearance.
Following this will be the installation of a temporary steel service bridge, on concrete foundations. To facilitate these works, there will be some single-lane closures during the day, in addition to night-time carriageway closures. Daytime closures will be timed to avoid the morning and evening peak traffic. Approximately 2000 tonnes of crushed rock will be delivered to site which will be used to protect the carriageway during the demolition.
Once the temporary bridge is installed, the public utilities ducts/cables currently crossing the A90 will be moved from within the existing bridge, to the temporary bridge. There should be no disruption to residents’ power, phone or broadband during this work. This work will take place between 10th and 24th November. The temporary bridge will not be accessible to pedestrians, and will be closed-off to prevent any unauthorised access.
Demolition Works
The demolition weekend has now been confirmed. Demolition works will take place between 20:00 Friday 24th November, and 05:30 Monday 27th November.
The A90 will be closed for this entire time, with all traffic being diverted onto the adjacent on- and off-slips. Whilst the diversions will not add any additional distance to journeys, motorists should allow additional time during the day on Saturday and Sunday. Routes for pedestrians and cyclists will not be affected during the works, however bus-stops will be temporarily relocated.
The bus-stop on the A90 northbound will be relocated to the junction at the end of Burnshot Road.
The demolition will be undertaken by a sub-contractor called Beattie Demolition, who are experienced in this type of work having recently demolished the B800 bridge as part of the south approach to the Queensferry Crossing.
Beattie Demolition will close-off the entire site and no access will be available for members of the public. The concrete and steel reinforcement will be ‘munched’ using specialist machinery. It will fall onto the protective layer over the carriageway below, and be transported away from site.
The road will be open to traffic for the Monday morning rush hour and over the subsequent days, the contractor will demobilise from site.
Community Liaison
Open events will be held in Kirkliston Library where representatives from the Council and Contractor will be available to answer any questions from members of the public. The dates for these events are confirmed as follows:
Tuesday 7th November 2.00pm-4.00pm, and
Wednesday 8th November 5.30pm-7.30pm
These are ‘drop-in’ sessions, so the public can arrive at any time, but there will be no formal presentation or meeting as such.
We will be delivering a letter to residents living in the vicinity of the bridge, with some further information for them.
