by any local authority in the UK - opened last year two months

Built by contractor Costain, the single carriageway scheme
provides traffic relief for the heavily congested A473 which passes
through the communities of Church Village, Ton-teg and Llantwit

controlled junction and around 3km of side roads which provide
links to the existing road network and the communities. Structures
consist of two road bridges, three footbridges, a pedestrian
underpass and two cattle creeps together with a number of major
culverts. To reduce health and safety risk and to simplify and
speed up construction the road bridges were constructed using
precast concrete arches while the culverts and cattle creeps were
constructed using steel arch designs.
Particular attention was paid to reducing the visual impact of
the bypass through the use of bunding and extensive planting of
around 117,000 trees. This reduces the effects of traffic noise on
the community that will be further supplemented by selective use of
A pedestrian and cycle community route has also been provided
along the whole length of the scheme. This links into communities
along the route providing a safe, sustainable alternative form of
