All about the roundabout


April 2017


Spring at last, and to celebrate, here is the latest A39 Falmouth Gateway (Treluswell Roundabout) e-newsletter. We aim to keep you informed as much as possible about the work we’re doing on this project, and – more importantly - how it may affect you. We hope you find it useful.

What's happening...

The construction of the new retaining wall at the side of the railway is taking place. This will take up to six months and once completed, will aid the widening of the new road. The wall will allow us to build a new lane joining the A39 from Truro to the B3292 into Penryn.

Once the retaining wall is complete the new section of the roundabout will be utilised to provide a dedicated left hand lane for Penryn. This is in the temporary condition to allow the construction of the remainder of the scheme.

Four-way traffic signals remain in place at night at certain times of the project when needed.

We are intending to start the next phase on 2 May, but this date is subject to change. During the next phase, the junction will operate as normal and the majority of work will be at night. Close to where the new roundabout will be located, the Redruth arm will be widened to direct future traffic towards it. The existing central islands will be removed and replaced with temporary surfacing. Traffic management will be in place, with each arm reduced to a single lane.



Other local works
Antron Hill, Penryn
Specific date not set, but should be within the next two weeks and last around half a day.
Line removal to complete recent layout amendment.  Low impact on the traveling public, owing to short duration of work with minimal traffic management. 

Penryn A394 at Edgecumbe
Work starts Tuesday 2 May for two weeks
New traffic islands being built as part of local safety scheme to supplement new lining recently installed. Two-way traffic lights employed with convoy working through the site to reduce traffic speeds for the safety of road workers. Some delays likely to be experienced but lights will be under manual control to help keep delays to a minimum.

Penryn campus crossing, Treliever
Work starts Monday 8 May for two weeks
Installing pedestrian refuge crossing point on the A39 linking Mabe to the Penryn Campus at Tremough. Works to include new pedestrian islands and adjustments to white lining.  Two-way traffic lights with convoy will be in place through the site to reduce traffic speeds for the safety of road workers. Some delays likely to be experienced but lights will be under manual control to help keep delays to a minimum.

A39 Treliever Roundabout
Work starts Monday 8 May for three weeks
Construction of low wall to support bank and protect South West Water main to rear of new cycleway and extension of the cycleway for approximately 80 metres on the northbound Treliever to Treluswell arm, opposite the Packsaddle Road junction.  Traffic management will be minimal and will allow all approaches to largely run without reduction in traffic flow. This is the final element of the cycleway improvement carried out last year. 




Keep up to date

Our dedicated Treluswell roundabout webpage is live. We’ll be adding the latest updates and urgent information here first, plus you can follow the links to the council website to read more of the project’s background, so why not add it to your favourites? There’s also a handy roadworks map showing what’s happening and where, and who is responsible for the works, and how well traffic is flowing. We hope you find it useful.



Before you go…
It will be quite a while before this happens, but we have been asked what will happen to the Cormac site once all the equipment has been packed up and the site offices removed. You’ll be pleased to know that the majority of the area will be seeded and planted, returning it to a natural state.

We want to hear from you

For up-to-date information on all aspects of the project, please visit the CORMAC website.

If you have any comments, questions or complaints about the work, please call 0300 1234 222 or email
You can find more information about the background to all the projects we are working on, and the overall masterplans, on the Cornwall Council website.
Thank you in advance for your patience and co-operation.


Delays speak volumes

We have had some people tell us that our traffic management has been causing some delays at Treluswell.
The only changes we have made to the road so far is the narrowing of the final five metres on the approach to the roundabout from Truro, which is the length of about one and a half cars.  This is essential for the safety of our workers and the site itself, but shouldn’t have an impact on journey times.
It’s more likely that delays are down to the recently completed safety scheme undertaken by Cornwall Council to remove the second lane at the accident black spot at Sticken Bridge.
Rest assured that when we do have traffic management in place, it will be closely monitored and adjusted where appropriate to make sure traffic flows as best as circumstances will allow.


Seen a problem?

If you see anything you think could be an issue, and it’s something we can do something about, let us know. We can’t be everywhere all the time, so we rely on you to inform us about any problems.
