Highway Heraklio – Ag. Deka – Viannos – , Section Ag. Varvara - Apomarma

The new National Road -Agioi Deka (Region Kasteli) is the most important artery in connecting the North with the South axis of Crete and the most important commercial center and port of the island, the city of Heraklio.

The project contains the design of two valley bridges with a length of 210m (six spans of 35m ) and 245m (seven spans of 35m) and the design of nine shorter bridges with variable lengths (12m to 25m). All bridges are precast – prestressed concrete beam structures. Precast beams are transferred in situ and raised to be placed on the high piers and abutments. They are circular in plan and have a longitudinal slope of about 6%. The overall width of the deck including the pavements is about 16.60m. They have a single traffic surface with one lane on each direction and barriers on each side. Expansion joints are provided at the abutments. The structural continuity of the deck along the length is provided with a continuity deck slab through the piers. Each pier consists of a rectangular hollow column of reinforced concrete and a cap beam on top of each pier which supports the upper structure resting on anchored laminated elastomeric bearings. At both bridge ends, transition slabs in conjunction with the abutments and the abutment wing walls form the transitional backfill. The piers and the abutments are founded on pile foundations.

The Land survey design includes: • The design of the topographic background for the road design • Cadastral work and acts actuarial The Survey Design involves the creation of the topographic background for the road design which includes contours and Land marks as : • Local traffic network. • Houses and other small structures (fences, retaining walls, etc.). • Fields and agriculture areas. • Utility networks (Electricity, water supply and irrigation, etc.) • Site elevations
