Dear Mr Fleming 

Reg 28 Report - After Inquest PORTMAN M J 17122023 

Thank you for your correspondence dated 27 August 2024.     

National Highways has investigated the circumstances of the incident and the items raised 
by the Coroner at this location. This includes undertaking a site visit on the 4th September 
2024 and talking to both West Yorkshire Police and Calderdale Council representatives. 

I can confirm that National Highways is the Highway Authority for the M62 motorway and 
the exit slip roads at junction 22. This extends up to the marked timber boundary fence 
and cattle grid at the interface with the A672. Beyond this point Calderdale Council is the 
relevant highway authority, including the A672 carriageway and immediate slip road 
interface. 

The slip road from the east bound M62 consists of a single wide lane dropping down from 
the mainline carriageway with open forward visibility. The alignment of the slip road 
includes two progressive bends, first to the left and then right, prior to the interface. Drivers 
leaving the motorway have a full and uninterrupted view of the slip road, including the 
changes in longitudinal alignment, for over 250m along the approach to the junction. 

At the end of the slip road, prior to the junction with the A672, a metal cattle grid spanning 
the full width of the slip road is installed to deter stray animals entering the motorway. The 
junction of the exit slip road and the A672 is controlled by ’Give Way’ signs.   

From the mainline diverge the slip road drops towards the junction which is located below 
the level of the mainline carriageway. An overhead concrete sign gantry, showing the 
destinations accessible at the junction, is located approximately 200m prior to the A672.

 From this position the forward visibility is such that there is a clear and unobstructed view 
along the slip road up to the junction. 

There are additional warning and direction signs installed along the slip road, between the 
gantry and A672 junction, as outlined below: 

i) 

ii) 

iii) 

iv) 

v) 

A warning sign assembly, consisting of a ‘hazard ahead’ triangular sign, together 
with a supplementary plate indicating ’cattle grid’ is located within the nearside 
verge, 135m prior to the junction. 

A large ‘map’ type direction sign is also located within the nearside verge, 
approximately 35m further along the slip road (100m from the junction). This clearly 
shows the A672 dual carriageway footprint and layout, indicating the destinations 
that can be accessed from the junction.   

A ‘chevron’ type sign, indicating the change of alignment to the right, approaching 
the junction interface, is located within the nearside verge, 10m prior to the cattle 
grid.  

The nearside and offside extents of the cattle grid are adjacent to timber boundary 
fences and are marked with vertical black and yellow reflective signs to visually 
highlight these areas. 

At the time of the incident in question there was also a post mounted ‘End of 
Motorway Regulations’ sign installed in the nearside verge, in line with the cattle 
grid itself. This was damaged in the collision and at the time of the site visit had not 
been replaced. 

The above signs are installed along the section of the slip road for which National 
Highways is responsible. Between the cattle grid and the A672 carriageway there are 
some additional traffic signs and carriageway markings. These are on the section of the 
slip road that is outside National Highways area of responsibility. The traffic signs are 
installed on both the near and offside of the carriageway interface with the A672 and 
consist of co-mounted ‘Give Way’ and 50mph speed limit signing. These were installed by 
Calderdale Council in April 2024 as part of a 50mph speed limit scheme on the A672, 
replacing the previous ‘Give Way’ signs in the same locations. 

There are also white thermoplastic carriageway markings in the form of Give Way triangles 
and broken white lining to delineate two traffic lanes and a ‘ghost island’ separation at the 
junction. The ghost island arrangement would normally consist of a hatched area which is 
not present at this site. 

Forward visibility along the slip road is clear and uninterrupted, and the current ‘chevron’ 
signing specifically addresses the change of alignment at the A672 junction approach.

 The traffic and signs installed at this location all comply with best practice guidance and 
current legislative requirements. The damaged ‘End of Motorway’ sign identified during the 
site visit is scheduled to be replaced by the end of October. 

We have access to historical records of collisions that result in personal injuries or fatalities 
for the motorway network and can confirm that, with the exception of this incident, there 
have been no other recorded incidents over the previous 10 year period at this location. 

In examining and assessing the current situation, we believe that the current layout and 
signing strategy adequately conveys the necessary and appropriate information regarding 
alignment and detail of the junction in order to enable the slip road and junction to be 
approached at an appropriate speed. We therefore do not propose any alterations to the 
current junction layout or speed limit along the slip road. 

I hope that you find this information helpful.  

Yours sincerely 

Operations Regional Director
