Structural design

Sigiri Bridge is a multi span deck-type plate girder bridge. The bridge is supported by two abutments 100m apart and two piers located 25m from the abutments. The bridge deck is divided into three spans with each of the two flank spans extending beyond the piers by 9m resulting in a mid-span length of 32m. The three deck spans are designed as composite steel and reinforced concrete decks consisting of 12 steel I-beams which together with the concrete above act as composite T-beams.

Collapse during construction

The mid-span section of the bridge collapsed on 26 June 2017. At the time, the flank span on the southern side of the river had been concreted and the placing of concrete to the mid-span deck had been completed the weekend before while the northern span had not been cast. 

Reconstruction launched

The contractor of the bridge COVEC accepted responsibility for the collapse of the bridge and the Kenyan Government have launched reconstruction of the works.

Reconstructed bridge opened to the public

Government authorities cleared Sigiri Bridge for use to the public on 31 August 2018.

Beam bridge

Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. No moments are transferred throughout the support, hence their structural type is known as simply supported.

Plate girder bridge Type of bridge

A plate girder bridge is a bridge supported by two or more plate girders.

Tied-arch bridge

A tied-arch bridge is an arch bridge in which the outward horizontal forces of the arch(es) caused by tension at the arch ends to a foundation are countered by equal tension of its own gravity plus any element of the total deck structure such great arch(es) support. The arch(es) have strengthened chord(s) that run to a strong part of the deck structure or to independent tie-rods below the arch ends.

Girder bridge

A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box.

Rigid-frame bridge Type of bridge

A Rigid-frame bridge is a bridge in which the superstructure and substructure are rigidly connected to act as a continuous unit. Typically, the structure is cast monolithically, making the structure continuous from deck to foundation. The connections between members are rigid connections which transfer bending moment, axial forces, and shear forces. A bridge design consisting of a rigid frame can provide significant structural benefits, but can also be difficult to design and/or construct.
