From mining to offshore oil exploration, the extractive industries have long been an important part of the economy of Liberia, a country rich in natural resources.

When a permanent bridge was needed at an iron ore mine far inland, it was an Acrow structure that was chosen to provide access for both vehicles and pedestrians.

The bridge supplied by Acrow was 51.82 meters (170′) long by 5.5 meters (18′) wide curb-to-curb, with an epoxy aggregate orthotropic deck. The one-lane structure was designed to support extreme heavy-haul loads.

Acrow bridges are well suited to meet the specialized needs of the mining industry; the modular design of Acrow’s steel bridging system makes installation easy and cost effective, and ideal for remote locations such as this, where installation of other bridging solutions would be difficult or impossible. Fully hot-dip zinc galvanized and engineered to exceed a 75-year service life even in the most challenging environments, the bridge was completed using local labor in three weeks, despite heavy daily rain.

Whether used for permanent or temporary installations, all Acrow bridges are supported by an on-site technician, providing expert instruction on site preparation, assembly and launch, through to final commissioning of the bridge, in order to ensure a safe, successful installation.
