Figure 1 shows a two-lane road beam bridge.

The beams are made of prestressed concrete; the span s ≅ 20 m, the height h ≅ 0.7 m, and the width (per beam) ≅ 1 m. The beams are placed side-by-side and supported by two column bents. Figure 2 shows a single-lane road beam bridge with steel trusses.

The beam type and geometry are the same as beam bridge 1, and the support consists of wall piers. Figure 3 shows a bridge entrance.

The truss is connected to the walkways; the height h1 ≅ 3 m, and the members are made of built-up sections. Figure 4 shows a connection between two members and the walkway.

The connection consists of a base plate and six anchor bolts. Figure 5 shows a schematic three-dimensional view of a span of beam bridges 1 and 2.
