Abstract
In constructing a stayed girder bridge, the end abutments and intermediate permanent bridge supports are built in place. The stiffening girder is formed of reinforced concrete or prestressed concrete and is built in sections at a location adjacent one of the abutments. As each section is built, it is connected to the previously produced sections by the reinforcing used, and the stiffening girder is moved from the one abutment toward the other by the length of the sections. When the girder reaches the other end abutment, a reinforced concrete tower is constructed upwardly from the girder at a location spaced from the abutments. A pair of stays are constructed of prestressed concrete each secured at one end to the other part of the tower. From the tower each stay extends in an opposite direction diagonally downwardly to and is secured to the stiffening girder.
