Propuesta de un diseño geométrico de una autopista a doble nivel para la calle 13 entre la avenida Boyacá hasta la intersección con la propuesta del anillo vial para Bogotá

Abstract

The road system of a city is one of the most important factors in the economic, commercial and industrial development of a country, promoting local development and quality of life of its inhabitants. The lack of adequate transport infrastructure, the high growth of the fleet, the large number of signalized intersections and delay in delivery of road projects; reduce traffic carrying capacity, reduce the efficiency of mobility and slows the progress of the city as secreted spatially and socially. The two-level highway proposal aims to unite Sector 4 of the ring road to the sector 7. The stretch this project (Sector 6) in conjunction with the Sector 7 brokers manage 13th Street, the Americas Avenue and 26th Street up the intersection with the road sector 1 ring; as this tour is extensive, by length it has been divided into two sectors: Sector 6 and Sector 7. Therefore, this project will manage a section of motorway to dual level from the municipality of Funza intersecting with the sector 4 and making his journey by 13th Street to the Av. Boyacá where it connects with the Sector 7. Avenida Calle 13 is one of the most important roads running through the city in the direction East - West. The project is designed to speed 100 km / h comprising a length of 9,068 kilometers from the municipality of Funza, K0 + 000 to the junction with the Sector 7, 380.00 meters before the road bridge of Boyacá Avenue in the K9 + 068.09. The geometric design of the two-level highway at 13, in general, contains: • Horizontal Alignment: 9 curves, including 7 spiral (ECE) and 2 single circular, with radius between 492 meters and 13,000 meters • Superelevations: between 2% and 4% • Vertical Alignment: 6 curves which 3 are concave and three convex, with a maximum elevation of 26.00 meters at the field level because of the existing elevated structures, and a low point of 7.00 m. Considering pending allowed. • Cross sections: Viaduct design is done with total width of 24.70 meters. 907 cross sections with an interval of 10.00 meters are created throughout the project For the constructive Development of the viaduct an investment of $ 1,075,395,296 724.69 , financing 19 Years Later ( 2035 ) Required Recovers , para 20 The year lifetime of the highway two levels , the value of the Investment UN is reached initially made the collection scam $ 1,232,527,401 000.00.
