Ozama Bridge. Dominican Republic

Expansion of roadway capacity between the east and west of Santo Domingo

The bridge over the River Ozama, known as the Juan Bosch Bridge, in honour of the writer and ex-president, establishes highway communication between the west and east of Santo Domingo. It is the straightening of the existing Juan Pablo Duarte Bridge, a metal suspension bridge constructed in the 50s.

Constructed to alleviate the vehicle congestion of the Duarte Bridge, the new bridge will increase capacity to 183,000 vehicles a day.

In order to achieve harmony with its surroundings, its design respects the silhouette of the Juan Pablo Duarte suspension bridge but, instead of designing a bridge of the same type, a cable-stayed structure was adopted.

The Ozama Bridge is a reinforced concrete structure having a total length of 647.10 metres. It can be divided into three sections: the viaduct providing east access, the main bridge and the west access viaduct.

Its deck attains a maximum height of 35 metres over the river and its pylons are 63 metres high. It has five spans, the central one is 180 metres long and lateral compensation ones are 457.50 and 35.95 metres. It is 33.5 metres wide that can be broken down into four circulation roadways, two lanes for a future urban train and pedestrian pavements. The deck is supported by forty-eight double cable stays that are separated from each other by ten metres. An extra-dorsal pre-stressing solution was employed, with greater deck rigidity.

Remarkable aspects

  • Constructed to alleviate vehicle congestion and increase roadway capacity to 183,000 vehicles.
