'Essential' repairs close Dorset roads
Road users in Dorset are facing disruption as a series of "essential" repair works begin in the county.
Starting from Monday, part of the A350 north of Blandford will be shut for five weeks to repair damage underneath.
Waterproofing and a concrete slab will be added to Waterloo Bridge in Christchurch over eight weeks to halt the deteriorating stonework there.
And from 19 September the "worn out" A351 between Poole and Wareham will be closed for five weeks.
The carriageway will have a deeper surface layer to last 20 years and meet the current standard for carrying heavy goods vehicles.
The repairs under the A350 centre around a culvert that is collapsing because of damage caused by tree roots.
When rebuilt it will incorporate an "otter run" to enable the animals to use the stream running under the road.
"Otters currently cross the A350 and only tend to use the culvert in the summer as it often floods during the winter," a Dorset County Council spokesman said.
Businesses, pubs and restaurants are expected to remain open during excavations to Waterloo Bridge.
The bridge will be closed to motor vehicles during this period, although pedestrians and cyclists will continue to have access.
