It is significant that the road which is steeped in history has been named after the founder of the City, Kempegowda, often abbreviated to KG Road. The road, which is hardly a kilometre long, begins at the Hudson Circle. 
The Hudson Memorial Church which was built in 1904 is a mix of gothic and classical architecture. It is now a part of Church of South India. 
K G Road runs along the periphery of the old Bangalore business centre. This is the shopping centre for the masses. The road also leads to the city railway station and the Kempegowda bus stand, making it one of the busiest road in the City. Despite being the busiest road, it is lined with trees. The entire stretch of the road is one way. There is a separate lane for autorickshaws. People throng along the road throughout the days. The pavements are abuzz with hawkers who sell second hand books and textbooks and application forms for jobs.
Being a centre of commerce, some of the earliest bank branches were set up here. Karnataka Bank, United Bank of India, Allahabad Bank, Canara Bank, Vysya Bank, Indian Bank, Bank of India, Punjab National Bank, Dena Bank, Corporation Bank an UCO Bank all have their branches here.
The longish Banappa Park runs parallel to the road. This park has been a venue of many cultural events and political meetings. A part of this park has been designated as Freedom Fighters Park with a Gandhi’s Charaka, installed on a stone pedestal. There is a temple adjacent to it. Next to it is a floodlit all weather basket ball court established by the Devanga Union Sports Association which was formed as early as 1946 and celebrated its golden jubilee in 1996.
There is a girls’ high school on this road run by the Corporation. One of the entrances of St Martha’s Road also opens on this road, although the main entrance is on the Nrupathunga Road. The taluk office, which was always crowded with people used to be located in a nondescript building. About two months ago old the taluk office was demolished. It is going to be replaced by an eight-storey building.
The Mysore Bank Circle is a prominent landmark named after the bank in the vicinity. The State Bank of Mysore was established in the year 1913 as Bank of Mysore Ltd. under the patronage of the erstwhile Government of Mysore, at the instance of the banking committee headed by the great Engineer-Statesman, Late Sir M Visvesvaraya. Subsequently, in March 1960, the Bank became an Associate of State Bank of India. 
It was started in a tiled-roof building where the present multi-storied building stands. The stone building in the European style of architecture was constructed in 1923.
Another landmark at the Mysore Bank Circle is the Anjaneya Swamy temple at what was known till recently as the Yelahanka Gate for this was the entrance to the old Bangalore city or pete from the Yelahanka side. Other landmarks include Cauvery Bhavan, comprising three blocks, one of which houses the Bangalore Water Supply and Sewerage Board.
There is a statue of Goddess Cauvery which pours water from a pot.  The heritage-like Asiatic building accommodates the Janata Bazar. The newly-built theatre-like structure is Shikshakara Sadhana of the Education Department.
The Federation House, which accommodated the Federation of Karnataka Chambers of Commerce and Industry (FKCCI), was established on May 8, 1916. Starting with W C Rose, an Englishman who was its first President during 1916-20, the Chamber has had a distinguished array of businessmen and industrialists as its Presidents.
Perhaps the road was and still is known for its cinema theatres.
A Rajkumar film used to be releases with great fanfare and giant cutouts on this road. Himalaya, Kempegowda, Majestic, Narthaki, Sapna, Santosh, State Picture House, Triveni, Menaka and Sagar are some of the theatres which has their glory in the past. Most theatres continue to function but some theatres have been replaced by Prabhat Complex, Alankar Complex and Geetha Complex.
The road ends at the Kempegowda Circle where there is a Ganesha shrine.
Located near the Circle is the oldest skywalk in the City which people actually use as there is no scope for jaywalking on this traffic intense road.
