Local coverage
We deliver traffic management across South Wales — Cardiff, Newport, Swansea, Bridgend, Merthyr Tydfil, the valleys and the M4 corridor — and across North Wales, including Wrexham, Deeside, the A55 corridor and the towns along the north coast, along with mid-Wales in between.
Wales is a long country with a road network shaped by terrain. Many communities are served by a single valley road or a single coastal route, so a closure does not shift traffic to a parallel street; it can remove access to a whole community or add a very long detour over higher ground.
That makes method selection the most important decision on a Welsh scheme. Convoy working, stop-go and signal arrangements often keep a route open where a closure would be unacceptable to the authority and to residents — and where a closure is genuinely necessary, the diversion has to be assessed properly, including height, width and gradient restrictions.
The work includes utility and civils programmes in the South Wales cities and valleys, A-road and M4 corridor schemes, A55 and North Wales trunk route works, long-duration development accesses, rural stop-go and convoy on mountain and valley roads, and event traffic management on constrained routes.

Local conditions
Welsh schemes are shaped less by traffic volume than by geography: where the road goes, whether anything runs parallel to it, and how steep and exposed it is.
Many valley communities have one main road in and out. Closing it does not divert traffic; it isolates people, blocks bus routes and can obstruct emergency access.
That is why so much valley work uses signals, stop-go or convoy arrangements, with maintained access for residents, deliveries and emergency services designed in from the start.
Where closure is unavoidable, the alternative route can be very long and may include narrow lanes, steep gradients, weight limits or low structures unsuitable for HGVs.
Diversion routes are driven and assessed, and signed continuously, because a driver who loses the route on a mountain road does not simply take the next left.
Wind, driving rain, fog and winter conditions on exposed and upland routes displace cones and signage and reduce conspicuity badly, and gradients lengthen braking distances.
Sign siting, weighting, cleanliness and inspection frequency all have to reflect that, and a stop-go shuttle on a steep or blind section needs its length and sight lines set conservatively.
The valleys and industrial South Wales carry a legacy of older utility apparatus, mine workings, retaining structures and narrow carriageways built for far less traffic.
Excavations there frequently reveal unexpected apparatus and need more space than planned, which changes the traffic arrangement mid-job under the permit conditions.
Cardiff, Newport, Swansea and Wrexham bring the urban set of problems: bus routes, pedestrian volume, cycle provision, loading and limited diversion options.
Pedestrian arrangements need barriers with tapping rails and workable widths, and bus swept paths need checking before submission rather than on the first morning.
The M4 in the south and the A55 in the north carry high volumes at speed, including freight and seasonal holiday traffic to the coast, and works there are tightly restricted in peak periods.
High-speed arrangements are delivered under Sector Scheme 12D with correct taper lengths, safety zones and advance signing, usually inside agreed overnight or off-peak windows.
Our process
Step 1
You send the location, the works and the dates. We check the road type, the speed limit, the highway authority involved and any local constraints before quoting.
Step 2
We produce the temporary traffic management design and scheme-specific CAD drawings for the arrangement your works actually need, not a generic layout.
Step 3
We submit to the local highway authority and manage the process end to end — permits, Temporary Traffic Regulation Orders, notices and conditions — and confirm approval in writing.
Step 4
Crews, signals, signage and barriers are allocated from our fleet of around 150 vehicles and team of around 300, and booked to the dates you have been given.
Step 5
Carded and ticketed operatives working under our supervision install to the approved drawing, with the arrangement checked against the drawing before works start.
Step 6
The scheme is inspected and maintained, damage and displacement dealt with including out of hours, phases changed as planned operations, and everything collected at completion.
Certificates are issued for your pre-qualification pack on request. We work direct for end clients and as a subcontractor to principal contractors.
Straight answers
Yes, North and South Wales plus mid-Wales — including Cardiff, Newport, Swansea, Bridgend, Merthyr Tydfil and the valleys, and Wrexham, Deeside, the A55 corridor and the north coast towns.
Wales is a planned coverage area with crews and equipment allocated from around 300 staff and around 150 vehicles. Planned schemes are booked to your dates, and emergency rapid-response call-out cover runs 24 hours a day, seven days a week.
Cost is driven by the road type, the method the terrain allows — closure, signals, stop-go or convoy — the equipment on hire, the duration, the number of operatives and travel to site, plus authority permit or TTRO fees. A long convoy operation on a mountain road prices very differently from portable signals in a town, so we quote each scheme in writing.
Yes, 24/7. That includes securing a route after a collision, carriageway failure, burst main or landslip-related closure, and attending damaged temporary traffic management.
Usually, yes — through signals, stop-go or convoy working with maintained access for residents, buses, deliveries and emergency services. Where the valley has a single access route, keeping it open is normally what the authority will insist on.
Yes, under Sector Scheme 12D registration with ticketed crews, in windows agreed with the relevant trunk road authority, with correct taper lengths, safety zones and advance signing.
Yes, end to end with the relevant local highway or trunk road authority: permit applications, Temporary Traffic Regulation Orders, notice periods and conditions, with approval confirmed in writing before your works start.
We assess them on the ground for width, height, weight limits and gradient before submission, then sign them continuously so drivers do not lose the route. On rural Welsh roads a missing sign creates U-turns and unsuitable rat-runs.
Yes, particularly on the M4, A55 and busy urban corridors where daytime occupation is restricted, with lighting and conspicuity planned for night working.
