Great Western Highway holiday congestion
The Great Western Highway through the Blue Mountains can experience significant congestion during long weekends and holiday periods. Find out how traffic congestion is managed.
Holiday congestion
Transport for NSW is working to help manage this congestion to minimise your travel delays and keep everyone safe on their journey through the mountains.
Due to the closure of the Great Western Highway at Victoria Pass, we expect delays may be experienced in Lithgow and on the detour route via Chifley Rd and the Darling Causeway.
If vehicles begin to queue eastbound at Scenic Hill, a traffic management plan will be put in place to prevent breakdowns on Scenic Hill.
Motorists will beheld at Scenic Hill to prevent traffic congestion, breakdowns, and start/stop movement up the hill. Vehicles are then released in small groups, allowing them to travel up the hill in one smooth movement, and preventing delays due to breakdown.

Project information
Congestion through the Blue Mountains
At the end of school holidays, long weekends and special events, a significant amount of traffic travels east on the Great Western Highway towards Sydney.
Due to the closure of the Great Western Highway at Victoria Pass, we expect congestion through Lithgow during the Easter weekend and autumn school holiday period.
Traffic incidents or road repairs can also lead to an increase in congestion.
In these situations, traffic queues may build down Scenic Hill.
Scenic Hill
Due to the closure of Victoria Pass, we expect congestion through Lithgow and on the detour route via Darling Causeway and Chifley Rd. Should traffic queuing extend down Scenic Hill, we will implement a traffic management system to reduce pressure on vehicles Increased breakdowns.
As traffic travels slowly up Scenic Hill, stopping and starting, vehicles can overheat and break down.
Tow trucks and emergency vehicles must navigate the congestion to access breakdowns and accidents.
These factors all add to congestion and create longer delays for all motorists.
On the final day of the 2020 June long weekend 32 vehicles broke down or overheated on Victoria Pass.

Why is traffic held at the bottom of Scenic Hill?
Transport for NSW is working to make journeys safer and minimise travel time delays during peak congestion periods.
Staff monitor traffic across the network and if vehicles begin to queue at Scenic Hill, the following traffic management plan will be put into place:
- Motorists are held at the base of Victoria Pass.
- Once there is enough storage room at the top of the hill, vehicles are released up in groups.
- Groups of vehicles travel up the hill in one smooth movement, free of stopping.
With this traffic management plan, vehicles are held on level ground at the base of Scenic Hill. This places less strain on vehicle engines and allows better access to Scenic Hill in emergency situations.
This Plan has been used on previous holiday periods/long weekends since October 2020 with demonstrated improvements in travel delays and elimination of vehicle breakdowns meaning everyone can return home safely.
This Traffic Management Plan has been shown to improve road safety, greatly reduce the risk of break down, and prevent further delays.
Plan your holiday return to avoid congestion
Transport for NSW encourages motorists to try the following steps to avoid congestion and queues on the Bells Line of Road, Great Western Highway and through Lithgow:
- Plan your trip – leave earlier, or leave later, to avoid the peak congestion times of 11am-7pm.
- Consider alternative routes – traffic management at the base of Scenic Hill affects east bound travellers. For your return to Sydney, the Hume Highway or the Golden Highway may offer a better alternative, depending on where you start your journey. However, please be aware that these Highways also experience some congestion at the end of school holidays and long weekends.
- Use public transport – for a day trip or for travel beyond the Blue Mountains, use public transport. For information on booking travel beyond Lithgow, please go to TransportNSW
