  • We've been pushing on with the concrete deck repairs since our last update on 9 May and we're grateful to our contractor, Volker Laser, for their hard work in maintaining good progress on our major project. We're pleased that the hydro demolition has finally finished and are grateful to all of our shared path active travel users for their patience while we finished this safety critical works. 

    We've now completed half of the repairs required to the cantilever edge soffits and this is progressing at a good pace, and the repairs to the concrete slab edges at the movement joint locations are about 75% complete. You'll see the safety boat on station most days as the scaffolders erect and dismantle four scaffolds on a rolling basis, working in synchronisation with the team repairing the concrete to keep work progressing efficiently.

    The waterproofing to the concrete deck is also around 50% complete as we took advantage of the recent good weather. This is more than 7,500m2 of deck and 30,000m2 of waterproofing product (because it's a four coat system). We hope for some more dry days in June to allow us to maintain the momentum, although the weather forecast is not great for the next week or so! Our contractor will look to "chase" the good weather to make the most of dry spells.  

  • The works are still progressing to a good pace and are on schedule to be completed by the end of September 2024. A lorry mounted concrete shot blaster has been used to clean the surface of the concrete deck over approximately 3000m2 of lane 2. This removes the final remnants of the old surfacing and deck imperfections immediately before waterproofing commences.  The waterproofing system is a four coat proprietary system from GCP Stirling Lloyd, called Eliminator. It is a cold applied and sprayed system, that will protect the concrete bridge deck below from contamination. The first coat is a primer to help with bonding the further layers and to help the system adhere to the bridge deck, and the second and third coats are a waterproof resin membrane. Barrels of the product are located in the back of a lorry, and a pump system, a bit like a power washer, allows the product to be sprayed through a nozzle onto the deck. The second coat is yellow in colour and the third coat is white. Although the two layers are an identical product, the colours are deliberately contrasted so that the skilled operative can see where they have sprayed, so that they don't miss any bits! The fourth, and final coat, is a bond coat, and is red in colour. This top coat will melt when the very hot asphalt surfacing is applied in the future, so that the waterproofing is fully composite with the concrete bridge deck and asphalt running surface. All four coats have been applied between joints 3 to 10, around 1400m2. The yellow and white coats are currently being applied between joint 10 to 13. 

    The outer concrete cantilever deck soffit repairs are still ongoing, with four scaffolds present on the bridge, now working closer to the Fife end of the bridge. This work will continue for a few weeks yet as we make essential repairs underneath the bridge. The hydrodemolition to the top surface of defective concrete deck ends are almost finished, with just a few remaining deck ends to be completed. The hydrodemolition works above the waterfront path will commence tomorrow, so please be aware, that for your safety, a small pedestrian/cycling diversion will be in place around the waterfront below the bridge. The bridge shared path will remain open, but all users will be diverted to use the lift, because the stairs will be closed. This diversion will be required for up to two days. 

  • Works are currently progressing well, although the wind and rain over the last week couple of weeks did hamper contractor efforts at erecting the scaffolding needed to provide access to repair the concrete soffits of the outer carriageway cantilevers. You will see up to four scaffolds that reach out over the edge of the bridge. Weights, or kentledge, in the form of precast concrete blocks located on the carriageway, support a cantilever structural arrangement of scaffold tubes to allow us to access the underside of the deck, without the need for support from the bridge itself. This arrangement helps us to be more flexible in reaching the areas that need repair. The windy weather lost us a few days of work on this element of our works, but in response, Volker Laser will be bringing more scaffold and labour resource to site and we are hoping for good weather as we move into the latter part of April and into May, so that the good progress can be maintained.

    All the old kerbs have now been completely removed (4.5km of concrete HB and L kerbs have been taken away for recycling) and all the asphalt has been scraped off the deck. Volker Laser are progressing with the deck preparation, and you will still see the fine milling machines at work as they remove the remnants of the bitumen used as deck waterproofing in the 1960's. More boot prints from the workers in the 1960's have been uncovered and these help connect us to our colleagues from the past! These imprints will be removed when the final deck preparation is undertaken just prior to waterproofing commencing. 

    The uneven concrete edges that supported the old movement joints continue to be broken out with hydrodemolition techniques and reinstatement follows soon after. The contractor commenced this work at joint 1 in Dundee and is now up to joint 21, and with 42 joint edges to prepare, you will see this work continue for a few weeks yet.

  • Today marks the start of our fourth week of works and we remain on programme. All the road surfacing asphalt, over 2000 tonnes, has been removed over the full length of the carriageway (which is 2250 metres long x 7.2m wide). Volker Laser, the main contractor, have also removed over a kilometre of both the lane 2 half battered and lane 1 high containment "L" kerbs for recycling. Wheeled excavators, or "Rubber Ducks", are carrying out this task carefully to avoid damaging the vehicle parapet and 20 tonne lorries are being loaded regularly to keep the bridge clear of kerb debris. Housekeeping of the site is very important on such a confined bridge, where access for plant must be maintained over the full length of the bridge at all times. 

    The kerb removal will continue this week, while at the same time Volker Laser continue to prepare the concrete surface for waterproofing by using the fine milling machines to gently scabble, or scrape, the surface. This will make sure that the waterproofing will stick to the concrete bridge deck. The concrete repairs to the movement joint edges are well underway, with high water pressure jets (or hydro-demolition) techniques being used to remove the defective concrete at the deck edges, where the old movement joints have been removed. This work is taking place in containment pods to keep all bridge users safe as the concrete is chipped away. As a result, and to maintain progress, shared path users might be asked to wait for a maximum of ten minutes before being allowed to pass the works area. We appreciate that this is disruptive and we apologise for all disruption caused to our users in this regard.  It also won't be long before you start to see scaffolding appear on the bridge deck, which is designed to cantilever over the parapet, so that repairs to the concrete soffits can start.  

  • We are starting concrete repairs on 20 March 2024. This involves using high pressure water jets to remove defective concrete. As a result, and for your safety, the works are self contained within work enclosures, protected in all directions. However, as a further precaution, we may ask pedestrians and cyclists to wait for up to ten minutes on the shared path until we can confirm that it is safe for you to pass. The shared central path will remain open at all times, as will the contraflow, but please expect delays if you are a walker or wheeler. We are really sorry for the inconvenience this might cause you.

  • Works have progressed well this week, with over 2000 tonnes of the original 1960's asphalt surfacing removed off site for recycling by sub-contractor E&J Douglas. The large planers took the asphalt layer off to a level above the existing concrete deck surface, so that it wasn't damaged. This is because the concrete surface installed between 1963 and 1966 is not perfectly level and we needed to avoid damage to the structural slab from such large milling machines. The next stage, which also commenced this week, is to use much smaller milling machines to gently scrape, or scabble, the remaining asphalt to expose the concrete surface without damaging it. This process takes a number of "passes" to make sure that this process does not damage the slab before surface preparation can take place to make sure that the new waterproofing will stick to the concrete. 

    The contractor, Volker Laser on behalf of Volker Stevin, have also started to remove the smaller Half Battered (HB) kerbs from lane 2 and to tidy up the concrete upstand that they leaned against. This is a labour intensive job and requires workers using spades to remove old bedding sand and mortar from the upstand. Volker laser have removed around 500 linear metres of kebing off site to date (just another 1750m to go before we need to remove the larger L shaped kerbs from lane 1!). Milling of the surface will continue for a few weeks yet as we need to scabble an area of approximately 16,500m2. 

  • Works commenced on Monday this week when we installed a contraflow on the northbound carriageway. Please do keep your speed down when using the bridge because this reduces marker post strikes, which need to be replaced by the traffic management team. The more posts we need to put back, the greater the disruption to traffic flow. We have installed a 30mph speed limit on the bridge for everyone's safety. If you drive an HGV please take extra care because the carriageway is narrower than you might be used to on the trunk road network. We have modified the Bridgehead roundabout and installed a double white line at the Fife end of the bridge to allow more room for larger vehicles to navigate onto or off the bridge, so please be prepared to slow right down and stay in your lane until you see the Roadworks End signs. You can still access Tayport and Newport-on-Tay from the B946 link road because we have modified the "splitter island" to allow us to keep the left turn from the southbound direction. Unfortunately, we cannot allow a right hand turn from the B946 link road but you can still access the bridge northbound via the Forgan roundabout. 

    The works have progressed well this week, where existing movement joints are being removed carefully by hand to avoid damaging the concrete deck below. A large Planer Machine will start to remove the original 1966 asphalt surfacing next week, so you'll also start to see a convoy of lorry tippers that will take the spoil off site for recycling. We have also been undertaking level surveys of the southbound carriageway over nights this week to give us a baseline for determining levels for installing the new kerbs. We survey at night because the bridge is much quieter and this reduces the bridge movement that is caused by the traffic "live loading" on the structure.  

  • THE SECOND phase of major works on the Tay Road Bridge is set to get under way next month.

    Carriageway closures and traffic management arrangements will be introduced on the south (Fife) bound, in a mirror image of similar work successfully completed last year.

    From Monday March 4, crossing will be via a contraflow arrangement, with the southbound closed and both Fife and Dundee traffic using the remaining carriageway on a single lane basis.

    The works will see the original 1966 surface completely removed down to the concrete bridge deck and waterproofing applied before a new asphalt surface is laid on top. In addition, 92 new expansion or movement joints will also be installed.

    Chair of the Tay Road Bridge Joint Board Cllr Gary Holt of Fife Council said: “We learned a lot from last year’s successful completion of similar work on the Dundee bound side but fundamentally we need to do these works to keep the bridge in good condition and safe to use for all users.

    “We’ve received positive feedback about the new surface and while we appreciate that there will be some inconvenience to bridge users, a new road surface will provide a safer and smoother journey across the bridge.”

    While the bridge will be accessible for most vehicle types, wide and abnormal loads will not be able to cross with traffic going in opposite directions separated by reflective marker posts and restricted to a single lane.

    The shared path will remain open in both directions at most times but may be subject to some restrictions during certain work activities. Users can keep up to date with the works on the bridge’s twitter account @tay_road_bridge.  

    During the works a maximum speed limit of 30mph will be in place along the length of the bridge to protect bridge users and contractors working on the site.

    The speed limit will also reduce delays as lower speeds have been shown to result in less damage to the marker posts, meaning less temporary lane closures to make good the damage.

    Contractors Volker Stevin are carrying out the works which it is hoped will be completed within six months.
