The idea behind toll-highway MP-203 was to reduce the traffic congestion in this part of Madrid's metropolitan area. In 2007, after having built 70% of its 12.5 km (and having spent €70 million on it), the constructing company abandoned the works because of problems with the connection with highway R-3, and the bypass of the high-speed rail tracks that could not be solved. These problems however, were known from the beginning, and the regional government let the works begin anyway. Today, the highway is used for leisure by joggers and bicyclists.
