Replacing the life expired River Tame railway viaduct, which sits in a flood plain, will involve off-site construction of a new deck structure. A pier will be built within a cofferdam erected a third of the way into the 15m wide river.
'Because we're working in the river, we've been talking to the Environment Agency to mitigate potential impact on river management, ' says Network Rail project manager Keith Riley.
A busy road-over-rail and rail-over-road bridge arrangement at Armitage will be replaced by temporarily re-routing the roads over bailey bridges alongside the original structure. This will then be demolished and rebuilt.
Gungate bridge sits in Tamworth town centre, with multiple connections to local roads.
The existing steel and reinforced concrete structure will be replaced with a new reinforced concrete bridge, built in three stages so traffic fl ow can be maintained during work.
A new bridge will divert road traffic over the railway, enabling the last remaining road level crossing between London and Crewe - at Hademore - to be removed.
