ew safety measures put in place on a

Costain road-widening project to protect

both the site workforce and errant drivers

was featured on TV screens and in the press recently.

Special collapsible barriers, installed at Girton,

near Cambridge, as part of the A14 Junction 31-32

improvement scheme, achieved valuable minutes

of publicity on BBC Look East, ITV East Anglia News

and Heart Radio, as well as in the regional press.

The ‘crash cushion terminals’ have been erected

to help minimise the effects of drivers who fail to

heed road warnings and try to enter the worksite or

veer off course.

The new terminals are placed at the end of tem-

porary steel barriers at access and egress points to

the worksite and consist of steel beams enclosing a

series of metal partitions and plastic boxes.

If a driver realises he is about to mistakenly en-

ter the worksite and tries to swerve back on to the

main carriageway but hits the barrier end-on, the

internal structure progressively collapses,

helping minimise the impact.

Importantly, this barrier is designed to

keep the car on the ground. Hitting a con-

ventional steel tapered terminal end-on

can flip a car into the air, either on to the

carriageway or into the worksite – with ob-

vious risks to other road users in the first

case and site workers in the second.

The crash cushion terminals are already

in use on some schemes in the UK, but the

Highways Agency’s A14 project is the first

time that they have been used as part of

temporary barriers in the east of England.

The scale of the problem was pointed

out by the Highways Agency, Between

2009-13, eight road workers have been killed and

317 injured while working on or near motorways

and major A-roads in England.

Costain is adding an extra lane to the A14 dual

carriageway between junctions 31 and 32 in a

scheme designed to increase road user capacity

along the route.
