This expressway was originally envisioned as an 8 lane road from the get-go, but was downgraded to 4 lanes in mid-2020 keeping the projected traffic in mind. The expressway will feature a 21 meter wide depressed median and all structures (bridges, culverts etc.) will be built up to allow for future widening to 8 lanes from the inside.

Four spurs have been proposed for inclusion in the Bangalore – Chennai Expressway project. Within those, only Spur-3 has been approved but with a reduced length of 2.050 km. Spur-1 has been subsumed into the 280.8 km Bangalore Satellite Town Ring Road project.
