| Abstract: |
The New Pumarejo Bridge over Magdalena River in Barranquilla, Colombia, is one of the most relevant bridges built over the past few years in South America. The bridge has a total length of 2173 m without expansion joints, divided in two access viaducts, 618 and 755 m long, and a cable-stayed central stretch of 800 m with a main 380 m long span (Colombia’s record). The access viaducts have 70 m long typical spans built by a movable scaffolding system (first realization in Colombia), whilst the cable-stayed stretch is built by free cantilevering from the pylons with 10 m long “in-situ” segments (well above the usual range). 3.65 m high, the cross section has a variable width that reaches 38.1 m in all the central stretch, what makes it the widest bridge in its typology (concrete box girder with central cable-stays). |
