Ι.MAVRAKIS & PARTNERS S.A.
STRUCTURAL DESIGN OFFICE 

The Bridge carries Dual Motorway "Egnatia" over a deep valley near Asprovalta village. The project includes the design of two identical Bridges constructed next to each other. Each one carries 3 lanes of the Motorway.

The Bridge has total length of 210.00m and comprises 6 simply supported spans of 35.00m each. The total width of the deck is 13.70m and is all intended for traffic (no footways). Traffic is contained with steel safety gantries.

The deck comprises 5 precast – prestressed beams, 1.90m deep. In-situ casted cross beams connect the precast elements over the supports. The slab consists of 10cm precast elements that are stitched together with 14cm of in-situ concrete.

Intermediate piers are formed as box-type sections in order to avoid buckling failure due to horizontal seismic loads. They are founded on rigid pile caps over large diameter piles.
