"Words cannot express my thanks to you all for making this presentation possible. My thanks to you for going beyond the call to instigate the project, it is refreshing to know that there are still some people out there who are willing to go the extra step to include all members of the community who for one reason or another could and in some cases feel left out as they are not able to join in with the majority of folks."

Burnshot Bridge is a 3-span structure originally constructed in 1964 when the Forth Road Bridge was built. The bridge is located over the A90 trunk road to the northwest of Edinburgh between the Queensferry Crossing and the City of Edinburgh.
The reinforced concrete deck of the bridge used half-joints, which are no longer permitted in current design codes. Following continuing deterioration of these joints, the bridge was restricted to single-lane traffic and after more than 50 years of use, was eventually closed in 2016.
Via the SCAPE Scotland Civil Engineering framework, The City of Edinburgh Council engaged Balfour Beatty to deliver a package of works which involved demolishing the existing bridge and the design and construction of a new bridge.
This complex project involved the following scope of works:
- Site clearance
- New foundations and superstructure for the new bridge
- Reinforced earth abutments
- 17 No 33 m single span bridge beams supporting a reinforced bridge deck containing stainless steel reinforcement to achieve a 120-year design life.
- Drainage
- Road pavement
- Road restraint systems
- Signs and road markings
- Landscaping
After more than 50 years of use, the original bridge needed to be closed to traffic in 2016 due to deteriorating joints and concerns about the structural integrity of the deck.
After the bridge was demolished in early 2017 a temporary pedestrian bridge was initially installed to support existing services and ensure the community remained connected to the local transport network whilst the works took place to build the new bridge.
More than 200 engineers, designers and employees from The City of Edinburgh Council and Balfour Beatty were involved in the project to build the new 33m wide state-of-the-art stainless-steel reinforced bridge.
The new bridge has an expected 120-year lifespan and will improve journeys for travellers for years to come. It was designed with input from active travel groups and provides improved cycling and pedestrian facilities including a segregated eastbound cycle lane and shared-use path.
Community benefit
Throughout the duration of the project, Balfour Beatty’s teams facilitated:
- 2 x school events (3 hours each)
- 2 x 2-week work experience placements hosted on site
- 2 x Graduate Engineers on project (42 weeks each)
- 4 x community engagement events – drop-in sessions at local library to keep the community informed of ongoing works and give residents an opportunity to see final bridge design using the virtual reality headset
