Two section bridge with 44.5 m arcs, 14.55 m wide and a height of 3 m. Two 0.9 m wide and 2.5 m high rectangular beams constituted the load supporting structures. The bridge passes over the Kwisa River where the river width is 18 m.

This tunnel of reinforced concrete has 2 constructions of 238 m in length, is 10.5 m wide between walls and 6.12 m high between the foundation and the slab.
The walls are joined with 70 cm thick slab.
The tunnel has 20 separate 12 m long segments. The arc radius is 400 m.

This was a restoration project of a bridge built over the Mondego River. Specifically, the pier was restored to an “A” shape.
The job was confronted with considerable dimensions at a height of 80 m.
