Reconstruction of Kochchikade Bridge (bridge no. 38/3) on Peliyagoda- Puttalam Road (a003) - Colombo
The new bridge replaces the existing bridge (Bridge No. 38/3) on Mahaoya River which has been built around the year 1936. Road Development Authority initiated a project together with the financial aids from the Government of Austria to construct a new bridge and the design and construction works were entrusted to Messrs Bilfinger MCE GmbH of Austria and Access Engineering PLC with the objective of widening the bridge with four traffic lanes while discarding the existing steel bridge.
The scope of the project was to construct a pre-fabricated steel bridge, 150 m long three span bridge with spans of 30 m, 45 m and 30 m. The bridge is 19 m wide and has two separate carriageways. Each abutment of the bridge comprises of 11 Number of bored piles and each pier comprises of 10 Number of bored piles. The deck of the bridge was built out of reinforced concrete with asphalt paving on the top. All the piles are of 1.2 m diameter and around 21 m in depth. The approximate lengths of newly built approach roads are 140 m towards Negombo and 110 m towards Chilaw.

Access Engineering PLC completed the project for the design and construction of Beira Lake Bridge and Associated Works under the Waterfront Integrated Resort Project, one-of-a-kind iconic mix development project of Waterfront Properties (Private) Limited, a subsidiary of John Keels Holdings.
The 35 m wide and 50 m long connection Bridge for the newly constructing Waterfront Integrated Resort consists of six lanes, with aluminium claddings on either side, flower troughs, high mast light towers and decorative lamps while the deck was constructed of precast concrete slabs and in-situ concrete finished with asphalt concrete. The deck, which rises from the side of Justice Akbar Mawatha, subsequently diverges into two key lanes which give easy access to the hotel development and condominium development. The design and supply of the steel superstructure was undertaken by Centunion S A of Spain and the design and construction of the substructure and related works was done by AEL.
