GONZALO 2020 bridge, Cable-stayed bridge over the Ozama River in Santo Domingo, Dominican Republic

The Puente Juan Bosch is a cable-stayed bridge of reinforced concrete over the Ozama River, linking Santo Domingo Este with the Distrito Nacional along the DR-3 highway. Its deck runs 647.10 m, carried by 48 double stays spaced ten metres apart from two towers 63 m high, with a 180 m main span. The 33.5 m deck holds four traffic lanes, two reserved lanes for a future urban train, and pedestrian walkways.

Built to relieve congestion on the Juan Pablo Duarte bridge, which carried 80,000 vehicles a day, the bridge was designed by engineer Leonardo Fernández Troyano of the Spanish firm Carlos Fernández Casado. Work began in 1998 under Leonel Fernández and was carried out by an FCC Construcciones, Dragados and Construcciones Civiles y Marítimas consortium. President Hipólito Mejía inaugurated it on 19 December 2001, at a final cost of RD$618 million.

The bridge is named after writer and former president Juan Bosch. It was designed to echo the silhouette of the neighbouring Juan Pablo Duarte suspension bridge, and its towers match that bridge's height, unusually low for a cable-stayed structure. It carries the DR-3 highway, linking Expreso 27 de Febrero with Expreso de las Américas.

The deck carries four traffic lanes plus two reserved for a future urban train, with pedestrian sidewalks on both sides. It links Expreso 27 de Febrero on the west bank to Expreso de las Américas on the east, next to the older Duarte bridge. The main span crosses the river on cantilevered segments, and the deck sits 35 m above the water.

The towers are unusually low for a cable-stayed bridge: they match the height of the neighbouring Juan Pablo Duarte suspension bridge so the two silhouettes harmonise. The main span of 180 m was judged too short for another suspension bridge, so a cable-stayed design was chosen instead.
