Stoke Gifford Transport Link
Known locally as the Stoke Gifford by-pass, the Stoke Gifford Transport Link is a new single carriageway road linking the Parkway North roundabout at Stoke Gifford with the A4174 Avon Ring Road at Harry Stoke.
The 1.6km new road will improve transport links between Bradley Stoke, Stoke Gifford and the A4174. It will also improve links to the motorway network and alleviate pressure on the surrounding roads.
The new link road will include new bus stops, bus lanes for MetroBus and local bus services and a pedestrian and cycle path. The road crosses the Great Western railway line and the Ham Brook via two new bridges.
Work is ongoing on the Stoke Gifford Transport Link. The new link road is being built by Griffiths and is expected to take around two years to complete. Work began in August 2015.
- Works to place the lower carriageway surfacing layers from Parkway North roundabout up to the Network Rail Bridge have been completed. The surface course has been added on the roundabout in addition to completing and the drainage works. The final surface course to the new link road will not be undertaken until all verge works are complete and will be one of the final operations.
- Works either side of the Hambrook Bridge that are dependent on a third-party Contractor that are not under the control of Griffiths have started later than planned due to late handover of the area by the third-party Contractor. However, Griffiths has worked promptly after handover of the approaches to complete drainage and earthworks ready for the lower layers of carriageway surfacing to be placed in early June.
- Throughout the length of the new link road we are removing excess spoil and distributing topsoil to landscaping areas, however these operations are weather dependant. Concurrently with this our landscapers will complete the planting and seeding to landscape areas.
- The final surfacing and road markings throughout the project have been completed to Oxleigh Way from the A4174. Remaining areas of surfacing and road markings will take place during July/August, however we are yet to be advised by the third-party Contractor when they will hand over the Hambrook Bridge to complete the surface course and complete the Link Road ready for handover to South Gloucestershire Council.
- The work in the Stoke Gifford Transport Link is shared between three contractors with Griffiths having responsibility for the roadworks. There are two bridges, one was handed to Griffiths some months ago by Network rail and good progress has been made with the road here. The other bridge is still in possession of the remaining contractor and Griffiths await access to complete the roadwork.
- We anticipate all drainage work will also be completed during April/May and laying the road base, binder and surface course from Park Way North Roundabout entrance to our site along to the Network Rail Bridge and down to the Hambrook Lane junction.
- Work will commence moving fill materials in readiness for filling the ground level on the approach to Hambrook Bridge from the north and south side to make progress in laying of the road over it. Earthwork will continue to shape the verges and work has commenced and is ongoing on the sound attenuation bund protecting the housing from the Network Rail Bridge towards Great Stoke Way. This will be topped with a two-metre-high acoustic fence nearer the completion of the road in the summer.
- Final surface course and road marking will be taking place in early April, from the A4174 up to the Oxleigh Way and from the north of the new Hambrook Bridge up to Hambrook Lane. Hambrook Bridge and the approaches approximately 300m long, will be surfaced along with all associated works once it has been handed over to Griffiths by the bridge contractor.
- A series of short duration closures of Hambrook Lane for final surfacing and anti-skid, lasting no longer than 5 days over a few weeks in May & June. We will post further details.
- Hambrook Lane will be closed for further finishing works – Farmers access, kerbing etc from Monday, 6th February 2017 for 2 weeks. A further final 1 week closure will then be required in May/June for resurfacing and road marking.
- The section from Parkway North Roundabout to the Network Rail bridge is now fully under way, we are taking advantage of the dry weather to press on with the drainage operations. Earthworks will recommence in February.
- The carriageway, from the Network Rail Bridge to the A4174 is now largely complete with landscaping & planting works well advanced.
- The Hambrook Bridge section being constructed by a separate contractor has not yet been handed over to Griffiths to enable us to make progress with the road at the point.
- Hambrook Lane will be closed for two weeks in from Monday 6th February 2017 to allow the construction of access tracks and the widening of the lane itself.
- At the A4174 junction, second phase works (including kerbing, traffic signal works and surfacing) will continue throughout January.
A4174 – for a period estimated as four weeks from early January to early February we shall be starting on the second phase of signalisation work on the east and westbound carriageways of the junction of the link road with the A4174. This will involve lane closures in both directions but only for evening work outside of peak hours from 6pm to 1am at the latest. Lighting towers will be erected and each night a short section of road will be worked on.
Hambrook Lane will be closed from early February for three weeks to conduct second phase works for construction of farmer’s access and lane widening. Advanced signage will be in place in advance and details of diversion is attached.
From the Parkway North roundabout to the rail bridge, due to unseasonably fine weather, we have made excellent progress on the road construction in this area. Progress will continue with the hope of tarmacking the area in the spring.
Having been handed the Network Rail bridge deck at the end of October we are now well under way with the carriageway construction works either side of the deck. The cut on the southern approach to the bridge has been completed, kerbed and will be surfaced (to binder course) in early December.
The fill on the northern approach is progressing well and will be ready for kerbing in the new year. This will connect the NR bridge to the Parkway North roundabout and will be surfaced in February/March weather dependant.
Installation of WPD cables is currently under way between Tudor Lodge and the A4174 (except Hambrook Bridge), this work will be followed by planting and seeding in these areas. Fencing work is already complete in many areas.
Traffic Management (off-peak lane closures) will be required in the new year on the A4174 and Hambrook Lane, to complete traffic signal ducting installation.
Latest Updates – October/November 2016
On 14th November Network Rail handed over the Curtis Lane rail bridge to Griffiths. Taking advantage of the fine weather we immediately began earthwork operations to build up the levels to the bridge in readiness for constructing the road over. This will continue throughout November and involve removal of the earth bund at the rear of Riviera Way, Earl Close and Voyager Close to supplement the earthworks at this bridge.
Whilst Griffiths is making good progress against programme completion of the whole scheme is dependent on completion of the Hambrook Bridge which form part of the Stoke Gifford transport link to reach the A4174. These bridge works are being undertaken by other contractors employed by South Gloucestershire Council.
Latest Updates – August/September 2016
The widening works on A4174 have been completed ahead of programme and has minimised the duration of the traffic management in preparation for anticipated greater volumes of traffic with the return of schools and UWE. The remaining work will be undertaken in the winter consisting of erection of traffic signals and some surfacing, white lines once the junction becomes live.
Works on the Maules Lane junction with the A4174 are due to commence in September and are required to enable new kerb lines and civils works. It is not anticipated this will cause any disruption to the A4174.
Second stage earthworks are now under way on the main carriageway, between Ham Brook and Tudor Lodge. We are taking full advantage of the current dry summer weather conditions to shape and compact the verges prior to the installation of ditches and fences. Ducting operations are also being carried out for traffic signals, CCTV, street lighting etc.
Lighting works are also ongoing with columns already installed from Ham Brook to Tudor Lodge. Griffiths are now awaiting the two other contractors to hand over the bridges they are working on within the Stoke Gifford Transport Link (SGTL) construction area so we may commence the earthworks for the final 30% of the project.
A significant milestone in the construction of the new Stoke Gifford Transport Link (SGTL, known locally as the Stoke Gifford By-Pass) is expected to be reached during the first half of June when the beams carrying the new road-over-rail bridge near Curtis Lane will be hoisted into position by contractors AMCO.
Once construction of the railway bridge is complete and AMCO have vacated the site (anticipated by the end of August), construction of the new road between the Parkway North Roundabout and Hambrook Lane can be continued.
A second bridge on the SGTL route, over the Ham Brook, being constructed by another contractor, is expected to be completed by October, after which construction of the remainder of the route through to the A4174 can be continued.
Griffiths are now anticipating that their work on the SGTL will be finished by early 2017, subject to the two bridges being completed on schedule.
