INTRODUCTION
Aziz Cross project is a signal free interchange with partial clover
leaf system and two additional directional ramps.
Clover leaf interchange Partial Clover leaf interchange with two
directional ramps instead of loops
INTRODUCTION
There are normally 32 conflicts at any interchange which are
completely resolved at Aziz Cross.

BASIC COMPONENTS OF FLYOVER
Bridge cross-section can be divided
into two portions.
1. Super StructureThis portion receives the live load
directly. For example, Box Girder
2. Sub StructureThis Portion supports the entire
structure and live loads. Piles Pile cap Piers Abutments

CONCRETE PILES
A pile is a vertical structural element of a deep foundation which transfers super structure loads to the earth farther down from the surface to a subsurface layer.
PILE CAP
PILE CAP
Pile cap is a thick
reinforced concrete mat that
rests on concrete piles that
have been casted into ground.
concrete pile cap distributes the
load of the superstructure (from
piers and abutments into the
piles.Pile Cap

PILE CAP AND PIER
PIER
A pier is a reinforced,
raised structure in form of
pillars typically supported by
well-spaced pile caps. It
transfers the loads from deck to
pile caps.
For this project, special shape
of pier is adopted. It as two
components
1. Pier Shaft as column
2. Pier Canopy as transom

Box Girder
Abutment refers to the substructure at the ends of a bridge span. It
supports; Super Structure load Live Load Lateral Earth Pressure

REINFORCED EARTH WORK
Reinforced earth wall is earth retaining structure and provided at
approaches (from road level to bridge level). The key components of a Reinforced Earth wall are geo-strips,
granular backfill and precast concrete facing panels. The frictional bond between the backfill supports the lateral earth
pressure and stresses induced due to traffic load.

PRE-STRESSED BOX GIRDERS
Bottom View of Box Girder
Piers
An optimal and most efficient design of beam is box girder. A box girder consists of enclosed tube with multiple walls.
The advantage of a box girder is that it better resists torsion. Having multiple vertical webs, it can also carry more load than an I-shape girder of equal height.
