Work has been continuing on two of the GWR's rail-over bridges
over recent weeks, at Gretton and at Laverton. Both involving
road closures and diversions. The directors of the
Gloucestershire Warwickshire Railway apologise to local residents
and businesses for the inconveniences caused during the closures.
However, Gretton bridge has now been reopened, three weeks early,
while work at Laverton is expected to be completed in December.
Work at Laverton involves replacement of a bridge that was
removed (with the railway's permission) some years ago to allow
heavy plant and equipment to gain access to the construction site
of a gas pipeline and pumping station. The cost of this work
is being met by the National Grid, whose predecessor Transco
removed the original steel span. A new concrete deck has been
cast and will be put in position soon. Being thicker than the
original steel deck, the track level will be a little higher than
originally, requiring a ballast ramp on either side of the
structure to lift the track to the required level. Completion
of the work will allow the Permanent Way department to install the
run-round loop here to allow trains to use the first two miles of
the Broadway extension.
Meanwhile, at Gretton repair work has been taking place
following collision by an over-height lorry attempting to pass
beneath it. Although stability and safety of the bridge was
not compromised it was necessary to repair the damage before
long-term corrosion set in which would eventually weaken the
bridge. The cost of the repair is being met by the insurer of
the lorry that caused the damage. The opportunity has also
been taken to carry out routine corrosion removal and cleaning of
the underside of the deck.
