A seagull treatment or seagull island refers to a traffic‑engineering setup that uses seagull‑shaped island to manage how vehicles turn at a busy T‑intersection. It creates separate turning lanes that guide vehicles entering and leaving the side road, helping to reduce crashes and delays.
See an example of a seagull treatment below.

Fitzwilliam Road, Old Toongabbie is a busy regional road carrying an average of 18,000 vehicles per day. Due to this high traffic volume, motorists often experience difficulty finding suitable gaps to turn right into Fitzwilliam Road from Greenleaf Street.
In response to increasing community requests, Council is proposing to install a painted ‘Seagull Island’ with associated line markings, including adjustments to the existing markings at this location to help motorists safely execute right turns from Greenleaf Street into Fitzwilliam Road in two stages.
The proposal will not result in any loss of on-street parking.
If there are no substantial objections to the proposal and it receives approvals from all relevant bodies, the construction work for this seagull treatment is expected to take place in May 2026.
