Bridge
Strengthening and Retrofit
Bridges
are a long term investment for road and rail infrastructure: throughout
their lives they require maintenance and repair and, with the huge growth
of traffic and traffic loads, they require strengthening and adaptation
for greater capacity.
Tamar Bridge Strengthening, England |
The Rodenkirchen Bridge project
typifies, on a grand scale, the challenges of bridge retrofit work,
which include
- the priority on maintaining
traffic flow
- technical complexity of
engineering the changes
- understanding the structure
as it is modified
- dealing with materials
of unknown or obsolete specification
- ensuring the safety of
the bridge users and the workpeople
- maintaining the integrity
of the structure
- maintaining the quality
of a landmark structure,
and indeed the retrofit process can be much more demanding than
building a new bridge

Cleveland Bridge has been associated
with retrofit work on many historic bridges including the Menai Straits
Suspension Bridge and Tower Bridge in London. Such projects range from
minor works to major long duration contracts, but every one presents risks
for the client and requires a competent experienced bridge contractor.
Over the last few years Cleveland
Bridge has acquired substantial experience in this field and can offer
a first-class service to bridge owners in the UK and, for larger projects,
worldwide.
