Expressway and highway interchanges have large land requirements, which is a particular issue in urban areas. The design must accommodate traffic demand in each direction, yet try to minimize land acquisition cost, impact on environmentally sensitive locations, and impact during construction.
KEI has particular experience in design and upgrading of urban interchanges, and has applied advanced techniques in their design and construction.
Twenty years ago, the firm designed the first 3-level interchange in Manila to alleviate traffic congestion. The Magallanes interchange remains a key node in Manila’s road network. Since then, KEI has been influential in preparing a comprehensive plan for interchange improvements in the capital, a number of which have been constructed.
In Thailand, KEI carried out strategic location planning and preliminary designs for fourteen interchanges, with the types of interchanges determined through consideration of traffic demand, topography, and environmental considerations.
