It runs along the coast of Kwun Tong before reclamation, spans south in Ngau Tau Kok and Kwun Tong, and ends at a junction with Tsui Ping Road, where it is succeeded by Lei Yue Mun Road.

Kwun Tong Road runs through the areas around Kwun Tong Bypass, Kai Yip Estate, the ex-premise of St. Joseph's Anglo-Chinese School, Kowloon Bay station, Lower Ngau Tau Kok Estate, Ting Fu Street, Ngau Tau Kok station, Millennium City, apm Millennium City 5 shopping mall, the roundabout with Hip Wo Street and Hoi Yuen Road beneath Kwun Tong station of MTR, and Bus Terminus.

Having traffic on the main route diverted into the tunnel, the roundabout functions efficiently.

Nevertheless, as road transport in the region becomes saturated, the roundabout still occasionally has traffic congestions.

Remaining buildings of the former RAF Kai Tak are located along Kwun Tong Road.
