CLIENT: Concesión Sabana de Occidente S.A.S.

LOCATION: Bogotá (Colombia)

KEY ELEMENTS: For the bridge design the standards of methodology of load factors and resistance (AASHTO LRFD 2012), Colombian Code of Bridges Seismic Design CCDSP – 2014 and American Association of State Highway and Transportation Officials, Guide Specification for Isolation Design, Edition (AASHTO LFRD 2010) were taken into account.

SERVICES: Feasiblity Studies/Conceptual Design, Detailed Design, Erection and Construction Engineering, Assistance During Construction

BUDGET: US$ -

PROJECT DURATION: Design 2014 - Site Supervision 2015-2016

PEDELTA’S KEY PERSONNEL: Leonardo Rosillo, MSc; Nelson Betancour, MSc; Alicia Serrano, MSc

PROJECT DESCRIPTION

The bridge is located on the left roadway of the road between K0+150 and K0+295.52 in section 7.2 of the highway Bogotá-Villeta (Colombia), horizontally crossing the channel of the Bogotá River, west of the city. This bridge will allow to decongest the entry and exit from the capital by 80th Street and is part of the concession Bogotá-Siberia-Villeta, a road that will have 81.6 km of dual roadway.

 

DESIGN/CONSTRUCTION APPROACH

The bridge is composed of an overall deck width of 14.75 m, which includes three lanes 3.50 m wide, hard shoulders 0.5 and 0.8 m wide, a pedestrian walkway 2.1 m wide, and side barriers 0.5 and 0.3 m wide. In addition, a 3.0 m wide bike lane was included. In longitudinal direction, the bridge has 3 spans: 25.7 m, 98.4 m, and 25.7 m. Accesses are made up of seven post-tensioned beams 25.0 m long between supports, separated approximately 3.0 m and a variable cantilever with a maximum depth of 1.50 m at each end, working on composite section with a 0.22 m thick concrete slab. The main structure will be designed as a bridge with parallel steel arches. Each arch is composed of a reinforced box girder, the bottom chord consists of two longitudinal reinforced beams with box section of 1400mm, the deck is composed of transverse beams with variable depth between 1250 and 980 mm and secondary longitudinal beams of 500 mm, working on composite section with 22 cm thick concrete slab, the arch hangers consist of 300 mm square profiles. The structure rests on abutments with deep foundation.

The structure was designed so as to cause the least impact to the flow of Bogotá River channel and to the traffic and public service networks, during both, the construction phase and structure lifecycle.
