North Devon Link Road, Bridge and Roundabout.

Introduction

The A361 North Devon Link Road connects North Devon and North Cornwall to the M5 motorway and the rest of the UK, acting as a crucial economic lifeline. Key objectives of the project include enhancing road safety, increasing traffic capacity, supporting regional economic growth and improving journey time reliability. The scheme focused on upgrading a 10-mile section of the route between South Molton and Barnstaple.
The works included the construction of new 2+1 wide single carriageway sections, a new grade-separated junction, two new roundabouts, improvements to existing priority junctions, and the creation of new pedestrian and cycle routes.

During the phased design and construction periods, TMS carried out over 20 Road Safety Audits. Our engineers undertook detailed inspections and assessments covering a wide range of safety-critical elements, some of which are highlighted below.

Safety-Critical Elements

Roadside features such as embankments, cutting slopes, drainage ditches and headwalls, to reduce the risk of vehicle rollover incidents. Rigid and heavy-duty items within verges, including signposts, lighting columns, trees, dense vegetation and telecommunications equipment, to minimise the risk of high-severity impact injuries.

Road Restraint Systems, ensuring they were correctly specified, located and installed to safely contain vehicles and redirect them away from roadside hazards.

Boundary fencing design, to reduce the risk of “spearing-type” injuries.

Signs, road markings and reflective studs, to ensure they were clearly visible, legible and correctly positioned to support safe driver navigation.

Street lighting provision, with particular focus on achieving appropriate uniformity at conflict points such as junctions and pedestrian crossing locations.

Skid resistance of the road surface, especially on approaches to bends, junctions and other higher-risk areas.

Visibility splays and stopping sight distances, ensuring compliance with design standards and suitability for the operating environment.

Pedestrian and cycle routes, reviewing surfacing, signing and lining to ensure safe and intuitive use.

What Our Road Safety Auditors Said

TMS engineers involved in the project, Hammy Aulak, Richard Marriott and Mike Fuller, commented:

“We were delighted to be involved in this significant infrastructure project. Our role allowed us to apply our expertise to help deliver a safer road for all users, while also enabling us to build on our knowledge of emerging technologies and best practice associated with large-scale highway schemes.”

A few more Road Safety Audits are planned to complete outstanding remedial works on certain project elements, with completion expected in early 2026.

Conclusion

Road Safety Audits remain a critical component of the highway design and delivery process, ensuring that schemes are safe, compliant and fit for purpose before opening to traffic. As demonstrated through this project, a structured audit undertaken in line with GG 119 enables potential safety risks to be identified early, supporting informed decision-making and helping designers, developers and highway authorities meet their statutory obligations.

For housebuilders, civil engineering consultancies and transport planners, engaging an experienced audit team adds value beyond compliance alone. Independent review, clear recommendations and a collaborative approach help reduce risk, minimise costly design changes later in the programme and contribute to safer outcomes for all road users.

FAQ

What is a Road Safety Audit?

Road Safety Audit is a systematic process for checking the road safety implications of highway improvements and new road schemes. The objective of the process is to minimise future road collision occurrence and severity once the scheme has been built and the road comes into use.

The audit takes into account all road users, particularly vulnerable users such as pedestrians and pedal cyclists. Having identified potential road safety problems, the audit then makes practical recommendations for improvement.

With these safety objectives in mind, the auditors need to ask the question “Who can be hurt here, and in what way?”

Why is auditor independence important in a Road Safety Audit?

Independence ensures the audit is objective and free from design bias, providing unbiased safety recommendations that highway authorities and developers can trust. Independent audit teams are a key requirement in GG 119, find out how we ensure our audit teams independence at TMS.

What happens after a Road Safety Audit is completed?

Following the audit, the design team prepares a formal response, often called a Designers Response, to each recommendation, outlining how issues will be addressed or providing justification where recommendations are not accepted. This audit response process ensures transparency and accountability.

St Mary’s Axe, City of London

St Mary's Axe, City of London

TMS recently conducted a Stage 1 Road Safety Audit associated with a temporary traffic management scheme on St Mary’s Axe in the City of London. The aims of the scheme were to minimise the impact of construction traffic associated with the redevelopment of 1 Undershaft (also known as St Helen’s Tower).

Located opposite 30 St Mary’s Axe (more commonly known as The Gherkin), the redevelopment, which includes the demolition of the existing St Helen’s Tower, would provide a new landmark tower in the City of London. Upon completion, the building will be the tallest in the City of London and the joint tallest in Western Europe, matching the height of the Shard. According to the architects, 1 Undershaft will also provide Europe’s highest publicly accessible viewing gallery and a ‘world-leading’ educational space curated by the London Museum. The development also includes enhanced public realm and a free-to-access public garden on the 11th floor of the building. A new public square featuring outdoor seating amongst trees and planting will also be provided.

The Works

The audited proposals comprised the closure of the existing footway on the southern side of Undershaft and the provision of a pedestrian diversionary route to the north of Undershaft. An alternative diversionary route was also proposed, passing between The Leadenhall Building and the construction site. Amendments to existing on-street motorcycle parking bays were also proposed, accommodating construction access into the site from St Mary’s Axe.

Vehicle activity in and out of the three gates into the site would be managed by marshals with concertina barriers, controlling pedestrian movement across the openings.

Stage 1 Road Safety Audit

At the time of our commission, the works had commenced with the area around St Helen’s Tower fenced off and the temporary pedestrian diversions were in place. Marshals were controlling pedestrian movement across the existing underground car park access during vehicle movements.

 

Following an assessment of the existing highway environment in context with the proposals, the Audit Team recommended that a temporary ramp be provided at the transition between the existing footway on St Mary’s Axe and the carriageway. Due to the temporary closure of the southern footway on Undershaft, pedestrians would be required to negotiate a full height kerb to access the diversionary route.

It was also recommended that additional temporary signage was installed to provide pedestrians with clear directions around the closures, with signage located so that it did not impede movement.

Heads of the Valleys Road Upgrade Officially Opens after two decades

Heads of the Valleys Road Upgrade Officially Opens after two decades

Over the last 12 months, TMS Engineers Harminder Aulak, Lee Williams and Mike Fuller have been busy carrying out Stage 3 Road Safety Audits on the last section of the A465 Heads of the Valleys project in South Wales. The 11mile (17.7km) section of brand new dual carriageway runs from Hirwaun to Dowlais Top and replaces the existing single carriageway road. TMS are extremely proud to have been involved in this project.

The final phase of the £2 billion Heads of the Valleys Road upgrade programme has now officially opened, marking the end of the project. The Welsh Government said it marked the completion of “one of the UK’s largest and most technically challenging road projects”. The £1.4 billion Section 5 and 6 Dowlais to Hirwaun final phase links the Valleys, South and West Wales to the English Midlands and beyond.

This has been one of the largest road safety projects TMS has been involved with in recent years. Since the summer of 2024, we have carried out 41 separate visits and produced 53 reports.  The process involved walking the majority of the new roads before they were fully opened to traffic and we estimate that our Engineers have walked a staggering 50km along the mainline, grade separated junctions and side roads. Good for the daily step count!

The programme was demanding due to the short time frames and deadlines to produce the audit reports before the “Permits to Use” were issued to the Contractor (as part of the phased opening).  Though challenging, TMS delivered in terms of arranging the audits (with the Contractor, Welsh Government Representatives, South Wales Police and Local Highway Authorities), inspecting the sites in both daylight and night-time conditions and producing the Stage 3 reports.

It was very satisfying to see that the vast majority of our recommendations to improve road safety and reduce the risk of future collisions were carried out promptly by the contractor. Many of the recommendations involved lower cost measures, such as improving roadside protection, ensuring street furniture was forgiving in the event of a collision (passively safe), road signs, markings and reflective studs provided optimum performance and facilities for pedestrians, cyclists and equestrians were safe to use.

We are confident that many of our recommended measures would produce a high economic rate of return in terms of collision savings, especially when fatal and serious casualties are taken into account. It is rewarding that we have played a part in ensuring the new road is as safe as possible as people travel smoothly and efficiently along the new road.

Over the time we worked on this project, our auditors built excellent relationships with our client, the Police and various other third parties. It was a pleasure working with all that were involved with this prestigious project. Andrew Carter from South Wales Police kindly provided the following testimonial.

Heads of the valley road

Andrew Carter – South Wales Police 

“The A465 Heads of the Valley Scheme was the largest civil engineering scheme to have been undertaken in Wales for well over thirty years. TMS were commissioned to carry out Stage 3 Road Safety Audits for the entire scheme with the lead auditor being Hammy Aulak and his colleague Lee Williams.

From the very start of the 40 plus audits completed on the scheme, the SWP Traffic Management Unit struck a good working relationship with both Hammy and Lee, and the combination of design knowledge and required specifications, coupled with over fifty years’ experience of the SWP officers, in relation to collision investigation and road user behaviour, in my opinion made a formidable partnership.

As a team I believe we identified some unique methods to offset any potential safety issues, which in fairness were rectified by the construction company and implemented quickly. Hammy was always prepared to look at any potential safety issues identified by myself and my colleague Ian Stephen and include them in his reports. We also found the expertise of both Hammy and Lee very helpful and their depth of knowledge and will be included in our annual PDR’s.

I firmly believe that what has been constructed is probably one of the best and safest sections of carriageway in Wales thanks to TMS with input from ourselves. I wouldn’t hesitate to recommend TMS for any future schemes, and it was a pleasure and enjoyable learning curve for the SWP Team.”

Portsmouth City Centre – Transforming Cities Fund (TCF)

Portsmouth City Centre – Transforming Cities Fund (TCF)

TMS have completed a series of comprehensive Road Safety Audits from preliminary design at Stage 1 through to the post construction at Stage 3, within Portsmouth City Centre, under the Transforming Cities Project.

What is the Transforming Cities Fund?

The TCF is a £2.45 billion capital grant transport fund aimed at driving up productivity through investments in public and sustainable transport infrastructure in some of England’s largest city regions. Improving access to good jobs within English cities and encouraging an increase in journeys, made by low-carbon and sustainable modes of transport, are key objectives of the TCF. The TCF also aims to support wider cross-cutting priorities such as tackling air pollution, delivering more homes and delivering apprenticeships and improving skills investments.

Our client was commissioned by Portsmouth City Council to design the highway improvement schemes under the Transforming Cities Fund (TCF). The aim was to provide bus and cycle improvements to the network, improve pedestrian links and journey times within the city. TMS were involved with auditing key highway areas of the city, at various stages, including City Centre North, City Centre South and Lake Road Corridor.

Charlotte St

City Centre North (Charlotte Street and Unicorn Junction)

For this area of the city, a new link was created between Cascades Approach and Unicorn Road, including a two-way bus lane. The junction with the A3 and Unicorn Road was redesigned to include a slip lane from the A3 to Unicorn Road. Charlotte Street was also redesigned to incorporate a one-way bus lane, which connects Cascades Approach to Commercial Road through the existing high street.

City Centre South

The City Centre South highway scheme removed the existing roundabout and installed a signalised junction. A cycle lane had been added to both sides of Station Street (eastern arm) and to the approach of the roundabout from Stanhope Road (western arm). New pedestrian crossings were also installed at each approach arm. An existing uncontrolled crossing had been signalised on Isambard Brunel Road at the location of a loading bay.

Lake Rd & Lake Rd 1

Lake Road Corridor

This scheme consisted of widening Lake Road (west) to create a west-bound bus lane and on-carriageway segregated cycleways in both directions. This involved diversion of existing utilities, new drainage and lighting and resurfacing of the entire road. Lake Road / Holbrook Road roundabout was retained with adjustments to the geometry. In Lake Road (east) the scheme included the provision of two on-carriageway cycle lanes, improvement to pedestrian facilities and upgrading the existing pelican crossing to a signalised crossing for pedestrians and cyclists.

Neal Roderick, who formed part of the audit team, commented “It was rewarding to work through the various audits from Stage 1 right through to Stage 3 and to see the designs come to fruition. If Stage 4 Road Safety Audits are commissioned in the future, we hope to be involved with these too. It will be interesting to see how the highway schemes are used by the various road users and if they have made significant improvements to the city”.
