Release (NWNOPS 01/0109) issued by COI News Distribution Service. 15
January 2009
In the first
installation of its kind in the UK drivers and rail users in the
North West are to benefit from a new barrier system that will
prevent bridge strikes along the M6 motorway.
As part of the £3.2m overhaul of Rose Whittle Bridge near
junction 28 of the M6 at Leyland, a new Delta Bloc System,
specifically designed for the protection of bridges, was installed
last month.
The bridge carries M6 traffic over the West Coast Main Line and
the blocks have been installed to prevent and minimise the impact
of bridge strikes. Incidents involving bridge strikes can cause
long delays for safety reasons as engineers need to check for
damage before re-opening roads or railway lines.
Work on Rose Whittle Bridge, which is half a mile south of
Junction 28, began in October this year and is due to be finished
later this month.
Temporary concrete barriers around the bridge have been removed
and replaced with the permanent Delta Bloc barriers DB 100AS-R.
The new design will provide better protection of the bridge and
the Highways Agency approved a containment level of H4b for the
project. A working width of W5 enables the provision of a full
hard shoulder. There will also be 500m of new surfacing added to
every lane in both directions.
Marshalls' new Delta Bloc Bridge Systems feature a precast
concrete barrier with a jersey profile to a single side. These are
joined together by 'connectors' and the system draws its
strength from each piece of the barrier being connected to the other.
Under a heavy impact, the barrier is designed to deflect in the
manner of a heavy chain. The non-structural bolts that secure the
barrier to the concrete foundations are also designed to shear off
which imposes lower forces on the bridge deck than conventional
concrete and steel barriers - thereby reducing the significant
costs of carrying out deck strengthening works required for the
provision of a conventional barrier.
Highways Agency Project manager Phil Hardy-Bishop said,
"This new protection will significantly reduce the impact of
crashes on the superstructure of the bridge reducing the threat of
delays to drivers and rail users. The M6 and the West Coast Main
Line are key strategic routes which is why we are investing in
this new system."

to reduce the risks of working on the roads. For the safety of
roadworkers and all road users, when you are approaching roadworks:
* Keep within the speed limit - it is there for your
safety.
* Get into the correct lane in good time - don't
keep switching.
* Concentrate on the road ahead, not the
roadworks.
* Be alert for works' traffic leaving or
entering roadworks.
* Keep a safe distance - there could be
queues in front.
* Observe all signs - they are there to help you.
