[4] The highway also provides the main route to Barwon Heads and Ocean Grove, localities along the southern coast of the peninsula.

Bellarine Highway begins at the intersection of Latrobe Terrace and McKillop Street on the western edge of central Geelong.

The highway eventually ends at Wharf Street East, Queenscliff, where it meets the Searoad Ferries passenger and motor vehicle ferry which operates across Port Phillip Bay to Sorrento on the Mornington Peninsula.

Bellarine Highway was signed as State Route 91 between Geelong and Queenscliff in 1986;[7] with Victoria's conversion to the newer alphanumeric system in the late 1990s, this was replaced by route B110, which continues on the other side of the bay at Sorrento to run along Point Nepean Road until Mornington.

The Geelong end of the highway originally ran along Ryrie Street in the Geelong city centre, but was relocated a number of blocks south to McKillop Street to remove heavy trucks from the shopping district in October 1997.
