Another loyalty mission for APAVE MADAGASCAR.
The rehabilitation of KAMORO Bridge is one of many construction, maintenance and operation projects implemented on the road network managed by the Madagascar Road Authority supervised by the Ministry of Public Works.
The general aims of the project are to:
- Improve the effectiveness and quality of movement of goods and people;
- Ensure the flow of traffic on the National Road no. 4 (RN4);
- Improve road safety and comfort for road users.
As part of this mission, our subsidiary in Madagascar was tasked with inspecting the solidity of the structures and their integral equipment. Initiated in September 2015, the project lasted 21 months and was completed last June.
The only road linking Antananarivo to the North-West region of the island, the bridge was built over the Kamoro River at Ambondromamy at KP 406+300 of the National Road no. 4 linking Antananarivo and the North-West cost of the island.
The bridge is a suspension bridge spanning 206.50 m built using steel and concrete, with a two-lane carriageway (2 x 3.50 lanes). The deck comprises two truss support beams supporting a concrete platform. This platform comprises 22 cm-thick prefabricated elements interlinked perpendicular to the pieces of the bridge.
The new bridge was positioned parallel to and downstream of the existing suspension bridge originally built in 1932, at an interaxial distance of 14 metres.
