Project Description

In October 2018 the Cali city council completed what has been considered the biggest civil engineering project recently built in the third-largest city of Colombia. The total construction cost has been in excess of 52 million dollars. The project comprises the extension of the Ciudad de Cali Avenue (also known as Calle 54), which will connect the southwestern and the northern parts of the city. Pedelta carried out the detailed design and construction engineering of the more relevant bridges along this extension.

Four road bridges and two pedestrian bridges have been designed and built. Two of the road bridges cross the Melendez River. Each bridge has an overall width of 15.1 m and carries three traffic lanes and a bike lane. The composite deck is composed by three steel box girders constant in depth with a top concrete slab. These bridges are simply supported with a span length of 57.3 m and 63.4 m.

The other two road bridges are overpasses, which also span the Jarillon River, with an overall length of 140 m and a span configuration of 40+60+40 m. These decks are made of composite haunched twin I girders with a top concrete slab and double composite action over piers.

The two pedestrian bridges are located beside the overpasses. The superstructure is a through girder warren truss. These bridges are integral, with the piles monolithically connected with the truss. Their span length is 61.6 m, and they are 3.50 m wide.

Design/Construction Approach

The use of prefabricated steel beams and trusses allowed construction time savings, minimized traffic disruptions, avoided the impacts associated with the occupancy of the river bed, improved workers safety, and reduced construction times and lifting equipment capacity, which translate into construction cost savings.
