S.A.Road along with M.G.Road are the two main arterial CBD roads connected with the Kochi Metro Rail and moving straight to Vyttila Mobility Hub, where three modes of transport (rail, water and road)converge and diverge, hence making it one of the most expensive and affluent areas in the city and state of Kerala.
Greater Cochin Development Authority (GCDA) & Rajiv Gandhi International Indoor Stadium are located along this road at Kadavanthra.
The original road was just a single lane as there was no cars other than those belonging to Royal family.
As the city grew, many commercial establishments started in this stretch which increased the traffic.
In year 2000, the Corporation of Cochin decided to go ahead with forcible land acquisitions, thereby the stretch from South Overbridge to Vyttila was able to relay into 4 lane road with some areas still under construction.
