Synopsis: The GBA is building flyovers, underpasses and railway overbridges that are being built to alleviate traffic congestion and connectivity issues in Bengaluru. While there have been some projects delayed, they are all important to building the city’s road infrastructure and future urban development.
With the ongoing urbanization of Bengaluru, the need for good infrastructure in the city has become a necessity to decongest the city and facilitate the growth of the city population. The Greater Bengaluru Authority (GBA) is coordinating a series of flyovers, underpasses and railway overbridges along the city’s major corridors to resolve the longstanding traffic congestion issues in the city. These projects are designed to boost connectivity and shorten travel times, but a number of them have experienced delays in the development process, including problems with land acquisition, the relocation of utilities, contractor problems, and coordination difficulties.
