Construction of Mwachande Bridge in Kwale Reaches 73 Per Cent Completion

The State Department for Roads reported that construction of the Mwachande Bridge in Kwale County has reached 73 per cent completion. The Kenya Rural Roads Authority implements the KES 537.58 million project across the Ramisi River.

Site photographs show substantial concrete work on the end supports and reinforcement activities in progress. These elements form the foundation for the bridge deck and approach connections.

In bridge construction, abutments act as the end supports. They connect the main structure to the approach roads on either bank while retaining the soil embankment and resisting horizontal forces from the superstructure.

Piers differ from abutments because they serve as intermediate supports in multi-span bridges. Positioned within the river or valley, piers carry vertical loads from the deck between the two end abutments.

The typical bridge construction sequence begins with site preparation and foundation works such as piling or dredging where needed. Substructure follows with the building of abutments and any piers using techniques suited to the river environment.

At the current stage of 73 per cent completion, the substructure elements including abutments and piers appear largely in place based on visible concrete work. Main beam closure has also occurred on this reinforced concrete T-bridge design.

Pending tasks centre on the superstructure and finishing stages. These include installation of prestressed concrete girders and T-beams, deck construction, surfacing, parapets and the approach roads that tie the bridge into the existing Milalani-Kikoneni-Mwangulu road network.

The 60-metre-long and 20-metre-wide structure uses strengthened reinforced concrete with composite materials for durability. Completion of the remaining works will allow the bridge to handle local traffic safely and reliably.

KeRRA teams continue to oversee quality control during these final phases. Safety measures remain active for workers on the elevated sections and in the riverbed areas.

Once fully operational the bridge will improve connectivity for communities in Kwale County. It will support movement of goods and people while reducing dependence on older or seasonal crossings.
