2 Bridges were curved CIP post-tensioned concrete box girders continuous in two 54m spans supported on single monolithic telescopic pier. The superstructure of the other 6 bridges are precast posttensioned girders spliced together to provide continuity with integral piers. The multi-column piers have different aesthetical features aesthetically. The abutments were spill-through, or closed conventionally or embedded with MSE walls. Another bridges is spanning over seasonal high speed streams, they are continuous 3 spans Box Beams Bridge. The bridges are aligned in different geometry, skews and curvatures. The main challenges in these bridges are: integral and semi integral bridges as new experience in KSA, comparable designs towards cost savings, sea water at or close to the foundations with high concentrations of chlorides and sulphates
