CLIENT: VSL

LOCATION: San Salvador (El Salvador)

KEY ELEMENTS: Cable-stayed bridge, with one centered plan of stays in the main span and two ruled surfaces for the backstays

SERVICES: Feasiblity Studies/Conceptual Design, Detailed Design

BUDGET: US$ 30 million

PROJECT DURATION: Design 2002

PEDELTA’S KEY PERSONNEL: Juan Sobrino, PhD, PEng, PE; Leonardo Rosillo, MSc; Nelson Betancour, MSc

PROJECT DESCRIPTION

Conceptual design for a cable-stayed bridge over the highway connecting San Salvador to the airport, in Miraramar Zone, El Salvador.

Due to its location in a heavy traffic road and the international access from the airport to the city of San Salvador, the proposed bridge would become an iconic bridge of San Salvador.

The retaining stays have been designed in two sections in order to achieve a fine spatial distribution that forms a ruled surface.

 

DESIGN/CONSTRUCTION APPROACH

The bridge has a 124 ft (38 m) long cable-stayed main span in order to allow the highway crossing with no intermediate supports, and includes an approach lateral span of 16 ft (5 m). In the approaches, the deck slab is 13 ft (4 m) wider in order to allocate the retaining stays without geometric interference with the access road.

The deck consists of a 39 ft (12 m) wide concrete slab, with maximum depth of 29’’ (0.75 m). The deck is supported by a semi-harp shaped section of stays spaced 19 ft (6 m), with anchorages placed in the 6 ft (2 m) wide median of the bridge. The slab is designed with curved shapes to achieve great visual slenderness.
