The Oblique Bridge was part of the M30 highway until the underground works in 2005 left it abandoned and slated for demolition. It is a valuable structure from 1969 by the engineer Fernández-Casado. The deck is a slender post-tensioned concrete trapezoidal slab with a complex, gently banked and curvilinear layout reflecting the ‘high-speed’ geometry of the highway.
The undergrounding project required the demolition of one of its abutments and foundations and the cutting of the ribs, leaving the bridge partially cantilevered. Despite this damage, the structure remained standing. The Madrid Río project renovated it into a pedestrian and cycling bridge. This rehabilitation involved delicate structural calculations to restore the rib heads and apply the appropriate tension, as well as the reconstruction of the lost abutment supported by the M30 tunnel diaphragm walls. The deck reinforcement allows for a plantation of pines that provides continuity to the vegetation on both riverbanks.
