DESCRIPTION

This overpass is located in the A1 connection to Leiria and it relocates the Coronel Pereira Pascoal street. The main feature of this structure concerns the road constraints, namely, its short radius curve defined by the layout. The overpass, with a total length of 69m, consists of 2 spans of 34,5m each. The deck structure, 12,5m wide, is a continuous, reinforced, longitudinally prestressed, concrete trapezoidal girder. One shall also highlight the transverse prestressing on the pier alignment in order to ensure an adequate transmission of vertical forces to
the support.
