Sindh Chief Minister Syed Qaim Ali Shah has said that the existing $800million ADB-funded mega city project will be redesigned and improved with the inclusion of mass transit schemes such as a light rail, costing Rs2.4 billion, to provide a solution to traffic congestion in the city for the next few decades. This was one of the salient features of the budget 2008-09, said the chief minister while addressing the post-budget press conference on the seventh floor of the New Sindh Secretariat on Tuesday.
