Interchange system for a roadway

An interchange system for a roadway including a first carriageway and a second carriageway, the interchange system comprising:

• a first ramp and a second ramp extending from a first portion of the first carriageway, wherein the first ramp is elevated with respect to the second ramp, the second ramp or a first intermediate portion ‘F’ of the first carriageway, and wherein the second ramp or the first intermediate portion ‘F’ extends towards and merges with a second portion of the first carriageway to facilitate traffic movement in a first direction over the first carriageway;
• a third ramp or a second intermediate portion ‘S’ of the second carriageway and a fourth ramp extending from a first portion of the second carriageway, wherein the fourth ramp is elevated with respect to the third ramp, or the second intermediate portion ‘S’, and wherein the third ramp or the second intermediate portion ‘S’ extends towards and merges with a second portion of the second carriageway to facilitate traffic movement in a second direction over the second carriageway;
• a connecting deck extending from the first ramp to the fourth ramp over and across the second ramp or the first intermediate portion ‘F’ and the third ramp or the second intermediate portion ‘S’ to connect the first ramp with the fourth ramp;
• a first traffic weaving section being defined at an interface between the first ramp and the connecting deck and a second traffic weaving section being defined at an interface between the fourth ramp and the connecting deck;
• and
• a primary ramp extending from the first traffic weaving section up to the second portion of the first carriageway, and a secondary ramp extending from the second traffic weaving section up to the second portion of the second carriageway, wherein the connecting deck interconnects the first ramp, the fourth ramp, the primary ramp, and the secondary ramp to facilitate the traffic movement in the first direction and the second direction.
