Work started this week on the installation of a new drainage system to solve flooding problems in the area by the Islas Marianas roundabout by the A-7 on Camino de Coín in Mijas. The town hall said the work, expected to take four months, will require some road closures, including a part of the road that leads from the roundabout to the Iceland store, where one lane will be rerouted into the street parking area.
