The project is primarily divided to two (2) major components: road bridges constituting Airport East Interchange and Haramain High Speed Rail Links connecting the railway track to airport stations (HHR).

There are four (4) different structures constituting the Airport East Interchange under the scope of Freyssinet SA namely AP2, AP3, AP9 and AP10.

AP2, AP3 and AP10 are road bridges composed of abutments, piers and precast deck whereas AP9 is an underpass that provides access from the North to the Ring Road Express Way.

The high speed rail under Freyssinet SA scope comprises 2 links connecting the airport to Madinah at the North (link #1) and to Makkah at the South (link #2). Each one of the 2 links is constituted of 2 lines A & B for entrance to & exit from the airport. The total length of the links is 4,965m. The structure of the links is composed of segmental precast deck supported by piers with a height up to 16m. Deep & shallow foundations constitute the substructure. Long spans up to 110m are executed in balanced cantilever technique.

All decks for road & railway bridges are in prestressed concrete, as per post-tension technique.
