Motorists are advised of changed traffic conditions this week on the Pacific Highway and local roads between Glenugie and Tyndale in preparation for a major traffic change.

From next week motorists on the Pacific Highway will be permanently moved onto about 36 kilometres of dual carriageway between Glenugie and Tyndale, weather permitting.

Motorists can expect traffic control, lane closures, reduced speed limits, intermittent stoppages and delays of up to 10 minutes between 6pm and 6am.

As part of this change the split interchanges at Glenugie and Tyndale will be open in their permanent arrangement and new northbound and southbound rest areas at Pine Brush will also open.
