Pretensioned, precast concrete hollow-core units used for interchange bridge project in Honduras

Abstract

Located about 6 km southwest of San Pedro Sula, Honduras, the interchange bridge project, a 4-span, 1-way structure with an overall length of 65 m, proved challenging because of its sophisticated design. With its horizontal and vertical curves, the bridge is an aesthetically pleasing infrastructure project. This article describes the design of the prestressed, precast concrete hollow-core units used for the interchange bridge, which also includes a 5.5-m-wide travel lane and two 0.65-m-wide shoulders.
