Latest on flood-affected major roads in NSW:

THE NEWELL HIGHWAY is closed to light vehicles in both directions between Narrabri and Coonabarabran due to water over the road at The Pilliga.

Motorists should divert via Gunnedah using the Oxley Highway and Kamilaroi Highway.

THE SILVER CITY HIGHWAY is closed in both directions from Broken Hill to the Queensland border due to flooding. Motorists should delay their journey as there is no suitable alternative route.

The Castlereagh Highway is closed in both directions at Angledool, near the Queensland border, due to flooding at Fingerpost Road.

From Walgett, motorists should divert via the Gwydir Highway to Moree and then use the Carnarvon Highway to Queensland. Vehicles over 26 meters must use the Newell Highway from Moree.

Some other major roads also remain closed due to flooding:

• The Kamilaroi Highway is closed in both directions between Curlewis and Willow Tree. Divert via the New England Highway and Oxley Highway.

• The Kamilaroi Highway also remains closed in both directions between Narrabri and Wee Waa. Motorists travelling between Narrabri and Walgett can divert via Moree using the Newell Highway, Castlereagh Highway and Gwydir Highway. This diversion is suitable for all vehicles but will add considerable extra travel time.

• The Newell Highway is closed to light vehicles in both directions between Narrabri and Coonabarabran. Motorists should divert via Gunnedah using the Oxley Highway and Kamilaroi Highway. Heavy vehicles are being allowed through at this stage, but should exercise caution.

• The Silver City Highway is closed in both directions from Broken Hill to the Queensland border. Motorists should delay their journey as there is no suitable alternative route.

In addition to state managed roads, some local roads managed by councils may also be affected
