Aberdeen Tunnel
The completion of Cross-Harbour Tunnel, Aberdeen Tunnel and other major thoroughfares around it increased traffic output, and thus a new road adjoined to Gloucester Road was built in the 1960s and opened in 1972, which was named "Waterfront Road"(海傍大道). The original Gloucester Road was then converted to one sided traffic heading westbound only. A number of flyovers was built. In 1980, the two roads was unified under the same name of Gloucester Road. The original Gloucester Road has been since known as "Inner Gloucester Road" or "Gloucester Road service road".
