The grade separated junction is required to provide access to the Tiverton EUE, a residential development located between Tiverton and Post Hill.
Construction of first phase of grade separated junction including westbound on and off-slip roads, drainage, acoustic bund, fencing and landscaping
Works are due to start in September 2017 and are programmed to complete in Summer 2018
A temporary 40mph speed limit will be in place for the duration of the works. Some overnight closures are needed to install a contraflow system (two directions of traffic on one side of the dual carriageway) for resurfacing of the A361. These will be published in due course.
All site traffic has to use the A361 for access. This is to protect nearby residents.
Devon County Council’s web site provide further information.
The general hours of work are 7.30am until 6pm Monday to Friday and 8am – 1pm on Saturdays. We have a tool box talk / briefing with the Works Manager at 7.30pm, so no large machinery should start until 8am. We are reliant on natural light to do this work so as winter closes in we may have to finish when it gets dark for safety reasons.
As the work, will be throughout the winter months predominantly we don’t envisage this will be a problem due to our climate. However, if we have an unseasonably dry autumn and winter we have water bowsers to dampen the work area to minimise dust.
The majority of the archaeological investigatory works required prior to start of construction were completed last year. The planning condition relating to archaeology has been fully discharged by Mid Devon District Council. A limited amount of precautionary approach may be necessary and this has been arranged. The archaeological report for this project has just been published online and can be accessed via this link.
The slip road is rising constantly from the level of the A361 North Devon Link Road to its highest point at the roundabout. The level of the roundabout has been kept as low as possible, however is constrained by the required headroom clearance for the bridge across the A361. We will be using soil from excavation work accessing the area from the A361 to use to create a 2.5m high acoustic bund with a 2m high acoustic fence that will be installed adjacent to the slip road to protect residents.
We will also be resurfacing the A361 in 2018 and using a higher grade of tarmac that will minimise road noise in future.
Example of Acoustic Fence
Under license from ‘Natural England’ we have managed to one-way gate and remove badgers from the outlying sets located on the works site. Under ecologist supervision these were destroyed on 5th September 2017. Three toads and a frog were relocated to the retained vegetation on the edge of the site during these works.
The next phase of site clearance is beginning on the existing verges with the vegetation being strimmed to 150mm above ground level working from the middle of the verges out to the retained vegetation. This will persuade reptiles to migrate to the edges of the site to the retained vegetation. Two days after, phase 2 will involve strimming the remaining 150mm of vegetation down to ground level, again working from the middle of the verge out to the edges. Another two days on, phase 3 will involve removal of the top soil.
All three phases will be supervised by an ecologist who will catch any reptiles encountered and release them in the retained vegetation.
