Introduction

2 x 40m Span Two Lane Roadways Through-Truss Steel Bridge Construction Project South Sudan

Despite worldwide competition, ZHM were selected alongside the Ugandan construction company Terrain Services to supply these Through-Truss Steel Bridges. So far we have overseen the construction of more than 30 bridges, of varying sizes, and the orders are still coming in.

Due to the poor state of Sudan's road network, we have to ensure that all parts required for erection are able to fit into 40feet and 20feet containers and the pieces relatively small to permit delivery of the bridges to the sites and reduce the amount of cranes needed for construction.

Unlike in previous years, the bridges are being designed to be long-term, and to withstand full high-way loading. These are not short term emergency equipment bridges with their narrow decks, rattling roadways, sagging shape and vulnerable trusses. And they are not the feeble single lane short span concrete bridges which were often all that were available.

The design of the bridges included two lane roadways. These roadways have multi level barriers to prevent collisions between vehicles and the main steelwork, and to keep vehicles on the straight and narrow (or rather, wide). The pedestrian footpaths are well segregated from the roadway. These features should increase the safety and welfare of the road users and, more so, the pedestrian users of the bridges.
