The project cost 15 million euros and included a new bridge on the Aragón river.
Canteras el Cerro placed the black retaining wall along the bypass road to solve the problems of flooding of the Ebro river.
It is about 6,500 meter long and the most important element of this roadwork, executed by Azysa, is a bridge over the Ebro river. That bridge has a double function as it is also an alternative in case of river floods, because usually the circulation has to be cut in case of floods, leaving Milagro isolated.
The works’ lead time was 18 months and was included in 2012 Navarra’s plan .
