Why is the Brussels Ring Road being redeveloped?

The Brussels Ring Road, also known as the R0, has not changed since it was built (between forty and fifty-six years ago). The many slip roads on and off (on average every 500m!) lead to dangerous weaving manoeuvres, traffic jams and accidents. In 2014 alone, almost 1100 incidents leading to disruption took place on the Brussels Ring Road. With the redevelopment, the road will be completely renewed and the handling of the traffic will be improved.
