Montel Civil Engineering has been engaged by the developer Robert Hitchins to construct a new roundabout on the A38 to the north of Gloucester city centre, near the village of Twigworth. The land to the east of the A38, in this area, has been ear-marked within the Joint Core Strategy for Gloucestershire as an area for residential development.
The construction of this roundabout will provide a safe access into the development land, and allow the subsequent access and egress for both future construction vehicles and residents.
The works are anticipated to be completed within a twenty week programme, and whilst as much of the works will be carried out without adversely affecting vehicles users of the A38, there will be instances where the configuration of the new roundabout will require traffic management to be implemented in order to protect the safety of both our workforce and members of the public (both road users and pedestrians).
The works required within the scope include; the protection and/or diversion of significant existing utilities (as well as the installation of new for the proposed development); the installation of a new storm water drainage network which also provides attenuation for surface water run-off prior to it entering the local, existing drains; the realignment of the A38 and formation of the new roundabout; and the installation of all necessary signage and street lighting in order to provide adequate safety measures for the safe use of the new road layout.
Update: 3rd October 2019
The Works are now complete with the new roundabout now open to traffic.
Update: 1st October 2019
The white lining is being undertaken in the morning and once completed we envisage the roundabout will be open to the public by midday.
We would like to thank all the local residents and businesses for their continued patience during the works.
Update: 9th September 2019
On Monday 9th September we will be extending our northbound lane closure to the entrance of Nature in Art, this will allow us to construct the final section of our footpaths which will give Twigworth Business Centre a brand new footpath linking it to the existing footpaths to the north and south.
For the 3 week duration of the final phase of works, Twigworth Business Centre will not be able to see the traffic lights as they have previously, the exiting traffic will be joining the end of the passing convoy as guided by the signage which will be put out in advance, in addition to this, one of our traffic management operatives will be there from 4pm onwards for the first few nights guiding the vehicles out accordingly.
Update: 16th August 2019
Latest Traffic and Pedestrian management plan:
Update: 9th August 2019
With Severn Trent Water completing the road crossing, we are now in a position to carry out our tie-in works to the eastern section of the A38. This will see us installing 2-way traffic lights from Orchard Park to the lay-by and moving the temporary pedestrian route into the carriageway. This will allow us to install the new kerb lines and service connections in preparation for our surfacing works which are programmed for week commencing 19th August. Later in the month we will be switching traffic to the newly constructed roundabout section so that we can proceed with the works to the western section of the A38.
Update: 26th July 2019
Now that BT Openreach have successfully relocated the existing BT cabinets and infrastructure, we can now carry on with the service protection works in these locations, these works will require the temporary rerouting of pedestrian around our works as shown on the drawing below.
What’s happening in August?
• Not connected to our works, but worth sharing with you is Severn Trent’s works at the pumping station adjacent to Orchard Park. North Midland Construction, working on behalf of STW are currently installing a 1.8m attenuation pipe. These improvements will reduce the risk of flooding during periods of heavy rainfall, reducing the risk of damage to properties. Information can be found @ https://www.stwater.co.uk/in-my-area/planned-improvements/twigworthgloucester/
They will be installing signalised traffic lights from Tuesday 6th August to install drainage pipework across the A38 carriageway to Twigworth Business Centre, the works duration is 2 weeks.
Should you wish to contact NMC, the contact is Viktoras Zabotka 07525 591414
• On 12th August we will be installing 2 way traffic lights to enable the final ducting and drainage connections to be made, this will allow us to lay kerbs to the entire section in preparation for the surfacing at the end of the month.
Update: 21st June 2019
Now that we are nearing completion the first phase of our extensive service protection works, we are now in a position to remove the traffic lights and the main temporary pedestrian diversion routes, we are planning on having this in place for Friday 28th June. Pedestrians will be routed through barriers on the original footpath route and diverted around our lay-by works over a short distance.
Update: 10th June 2019
Following extensive service location works, our next phase of works is to locate and protect the services within the existing footpath opposite Twigworth Business Centre, to do this, we will temporarily divert the pedestrians through a safe corridor on the existing southbound closed lane carriageway, whilst using this temporary passage, pedestrians will be guided by barriers and signs. Our intention is to keep the disruption to pedestrians and motorists to a minimum, and we will get the carriageway back open to two-way traffic as soon as possible.
Update: 31st May 2019
A38 Lane Closure Monday 3rd June – Friday 21st June
In order for us to carry out phase 1 of the of the new roundabout construction, we will need to close the southbound lane on the A38 between Twigworth and Longford, this is to ensure the safety of our workforce whilst the works are carried out. At Peak times between 07:00 – 09:30 and 15:30 – 19:00 the lights will be manually operated to ensure traffic build up is managed accordingly.
Update: 28th May 2019
In order for us to carry out the remodelling of the northern end of the lay-by, it will be necessary at times to temporarily close this access to allow our construction works to be carried out. We appreciate road closures are inconvenient, but in order to keep you and our team working on the road safe it is necessary. We have planned the work so we can be in and out as quickly as possible and have tried to do it at a time that will minimise any inconvenience. The first closure is planned for Thursday 30th May and we should get the layby reopened for the weekend.
Update: 23rd May 2019
Pedestrian Management Phases 4 and 5 23/05 – 06/06
In order for us to more efficiently expose and map the services and concrete protect them where required, the pedestrian diversion will be undertaken in 2 phases as shown on the attached drawing.
Update 21st May 2019:
From 22/05 to 24/05
Phase 3 pedestrian management phase for our trial hole works take place at Twigworth, Glos.
Update 17th May 2019:
In order for us to carry out investigative service location works, there will be occasions where we will need to temporally divert pedestrians around our works via a temporary footpath. These temporary footpaths will be made up of compacted crushed aggregate and temporary red/white barriers and signage will safely guide you around our works.
We will endeavour to complete the investigation works in the working day so we can open up the footpath by 5pm, but please be patient whilst we carry out these essential works and as always we thank you for your co-operation.

Frequently asked questions
Q When will the scheme start?
Construction is due to start May 13th 2019
Q. Will the A38 be closed to traffic during construction? Will there be a detour?
Some traffic restrictions, including speed restrictions and lane closures will be unavoidable at certain points during the construction of the scheme.
It will be necessary to carry out the final surfacing works and drainage connection via localised night time closures of the A38 at the end of the scheme in September. These will be in place from September 23rd – September 27th from 19:00 – 06:00 daily (a diversion route will be provided and signed accordingly) – in order to protect both members of the public and the workforce during these activities. This diversion will be advertised, and ample notice will be provided to all stakeholders.
Q. How will the road construction affect businesses and residences on the A38?
Whilst every effort will be made by Montel Civil Engineering to minimise the impact the roundabout construction will have on businesses and residents on the A38, there will be a need to implement traffic management controls whilst certain operations are being carried out. We would hope that these do not adversely affect the ability of local residents and businesses to access/egress their properties. If you have any concerns, please contact the Project Manager: Nick Rowe 07921 455 557
Q. How will I get to my property during construction?
All property access will be maintained throughout the project duration.
Q. What hours will the construction team work?
It is anticipated that the site team will be at work from 7.30am to 5pm. Normal levels of construction noise are to be expected.
Q. When will the traffic lights start on the A38?
2-way Traffic Signals will be in place from 12th August through to the end of September. You can view the latest information in the ‘Updates’ tab.
Q. Will these lights be manually controlled during peak times?
To alleviate the build-up of traffic, the lights will be manually operated during the peak traffic flow periods through Monday to Friday.
Q. How long can I expect to be delayed waiting in traffic?
This obviously depends on the volume of traffic and therefore will fluctuate during the day. We would advise that should alternative routes be available, then these are used. Montel Civil Engineering will monitor waiting times and provide feedback.
Q. Are the temporary traffic lights going to be in place seven days a week?
Whilst we endeavour to remove the temporary lights when not required, the final phase of our scheme requires us to divert the traffic around the new roundabout whilst the final section is constructed, to do this we require temporary traffic lights to be out for the full duration of this temporary traffic diversion.
Q. The traffic lights are still in place, but I can’t see any works being carried out. Why are they still there?
There is nothing more frustrating than seeing road works in place but no activities being carried out. Montel Civil Engineering are aware of this and the perception it gives. We can only state that the lights will only be left in place if we have any safety concerns that prevent their removal – or if the works programmed for that day dictate that we need to have them in place. There are a number of activities that will be weather dependent, and as such there may be instances where the lights are on in readiness for that day’s scheduled works, but the conditions (either at that time or forecast) dictate that those operations cannot be carried out. When this becomes apparent, the lights will be removed.
Q. Where can I find updates about the scheme?
There will be a dedicated website which will go live on Monday 13th May and be updated on a regular basis, all information can be found here http://montelcivilengineering.co.uk/portfolio/twigworth-roundabout/ We will also be tweeting about the scheme as it progresses follow @Montel_CivEng.
Q. When will construction end?
The project is planned to be completed September 2019.
Where will the road closure signs begin, will it be at both ends of the diversionary routes?
Yes, Road Closure signs will be placed at each end of the diversion route.
How will you monitor and ensure that HGV lorries do not use the lanes around Twigworth throughout the duration of the night. each night?
Clear Signage will be in place along the sections of road prior to the road closure section on each side. Frog Furlong Lane and Down Hatherley Lane will have No HGV Signs at their entrances as a safeguard.
If the weather affects the work, how much longer will this work take?
This is an unknown factor
What time will the heavy machinery usage end each evening?
Our intention is undertake the heavy machinery works at the start of the shift leaving only the quieter surfacing works happening thereafter.
How will you manage the vibrating roller used for the purpose of levelling the tarmac with minimal disruption and noise to the residents?
The vibratory equipment used to compact the surfacing vibrates at a very low frequency, the compaction required is called a near surface compaction type therefore will not be felt in the surrounding ground even at short distances away. The noise levels on the compaction equipment used by our surfacing contractors is extremely low due to them having the latest technologically advanced equipment.
How will you ensure that any contractors and deliveries to site throughout the night cause minimal noise? Who will monitor this noise?
Road wagons delivering the surfacing materials will not be allowed into the vicinity of the works until they are required to dispense the materials into the paving machine, plant and machinery will be switched off when not being used. noise monitoring will be done via specialised equipment as approved by the HSE
Will there be additional flood lit lighting used overnight during these works and how will this be managed to ensure that there is no intrusive light into nearby households?
No, our surfacing contractors use the very latest light technology on their equipment which only lights up the areas in and around the machines.
