On the CM-410 road of the Region of Castilla La Mancha, within the Alto Tajo Natural Park: between the towns of Poveda de la Sierra and Taravilla (Guadalajara) a new bridge over the Tagus river is projected and built.
The bridge, noticeably deviated concerning the river channel, jumps the Tagus River in a single span through a pair of steel arches of improved resistance to corrosion, having adjacent spans on the slopes. The arches are bi-articulated with ball joints in the abutments and are braced by crosses of Sant Andrew. On these arches, the pillars support two metal trough beams in which a reinforced concrete slab is connected, which materializes the road deck.
The foundation of the arches is made on the right abutment directly on ground using concrete plinths. In the left abutment, the rock was located very deep, and micropiles were projected with an embedment of 7.00 meters in rock. The micropiles leaned in various directions to pick up the arc guideline and transverse wind thrusts.
