The Bengaluru-Chennai Motorway, which spans 105.7 km in State, has a total length of more than 12 km of asphalt surface. An average of 30% progress has been made by the four contractors on the $5,9711.9 million project. By the end of August 2024, the project is expected to be finished. More than 98% of the land needed for the greenfield project, according to official sources at the National Highways Authority of India (NHAI), was available. 3,4765.4 million of the total would be used for construction-related expenses alone. Depending on the region, the road's height could range from 3 to 5 metres. For the project, almost 2.5 crore cubic metres of earth would be needed. The earth is gathered from surrounding districts where the corresponding district authorities and concerned departments were providing assistance. Fly ash is not required for the contractors. They can use the ash if they receive it. It is no longer required, according to a source. The four-lane wide road would have a number of structures, including 147 culverts, six toll plazas, five interchanges, three rail bridges, 31 major bridges, 25 minor bridges, and 71 vehicle underpasses, overpasses, and light vehicular underpasses. Two truck lay bays and two rest spots would be available for use by motorists on the roadway.
