Geometric design is a technique used to solve traffic problems in large cities that have a large influx of vehicles and that develop over the years mobility problems that affect the time and life of users who use these road passages. The objective of the following work is to propose a road alternative by geometric design through a slope crossing that contributes to the decongestion of traffic that is affected at the intersection of Avenida 26, between Carrera 19 Bis and Carrera 19, where a speed reduction is diagnosed and with long rows of vehicles, with high waiting times due to the traffic lights that are presented at the place. It is achieved as a result, the final model of the overpass that will help the decongestion of traffic and allow the continuity of vehicles without interrupting the passage of the two road arteries of the city. Also, the proposal of variants and alignments that improve circulation at all crossings and turns.
