Elekahia Bridge

Location: City of Port Harcourt, Nigeria
Status: Completed 2011

Project Description

The Elekahia bridge is a new 32m long railway bridge above a main road in the city of Port Harcourt, Nigeria. 


The initial plan was to replace an existing bridge, with a new one. However, as site works in this location would cause a significant disruption to the bottle necked traffic, it was decided to relocate the entire intersection 100m eastwards, thus reducing the impact.

Construction
To accommodate the existing lay of the land, the bridge was designed utilising top-down construction, where the bridge was built from deck level, downwards.
Piled foundations were drilled from deck level and the deck was then cast directly onto the ground.

After casting the post-tensioning the deck, the soil beneath it was excavated, down to the proposed level of the new road.
