Safety changes have been introduced on the Bells Line of Road, with Transport for NSW rolling out updated signage and targeted speed limit changes across the Blue Mountains corridor.
The changes follow a series of speed zone reviews completed as part of planning for $100 million in Federal Government-funded safety upgrades.
The reviews focused on three sections of the Bells Line of Road: Bell to Mount Wilson, Claustral Causeway to Berambing, and Berambing to North Richmond.
Why does Bells Line of Road matter for freight?
Bells Line of Road is a State Road and a key link between Sydney and the Central West.
The corridor carries a mix of local traffic, tourists and freight, including heavy vehicles travelling through steep, winding sections of the Blue Mountains.
Transport for NSW Executive Director Damien Pfeiffer said the route’s geography and traffic mix were central to the reviews.
“The road passes through the Blue Mountains, so it features many winding parts and some significant upward and downward sections, and caters for a broad mix of local, tourist and freight transport, including heavy vehicles,” Pfeiffer said.
The road also passes through towns, property access points, and intersections, with existing speed limits ranging from 60 to 100 kilometres per hour.
What speed changes have been introduced?
The 100 kilometres per hour speed limit between Bell and Mount Wilson Road has been reduced to 80 kilometres per hour in all conditions across a 6.4-kilometre section.
That section had previously been 100 kilometres per hour in dry conditions and 80 kilometres per hour when raining.
A new 50 kilometres per hour speed zone has also been introduced through Bilpin for 470 metres, where on-street parking is located.
Transport for NSW said the change is aimed at improving safety for drivers and pedestrians.
Other speed zone adjustments include extending the 60 kilometres per hour section at Bell further east by 100 metres, reducing the 60 kilometres per hour section at Bilpin Fruit Bowl by 400 metres at the western end, and extending the Bilpin 60 kilometres per hour zone 400 metres west to Horsfield Road.
The reviews found existing speed limits between North Richmond and Bilpin were appropriate, meaning no changes were needed in those sections.
How will the changes affect travel times?
Transport for NSW said the changes will add an average of about two minutes to trips on Bells Line of Road.
The agency said the trade-off is expected to deliver safety benefits for all road users and residents.
While some speed zone boundaries have moved by up to 400 metres to better reflect the road environment, the overall length of 80-kilometre-per-hour zones will not be reduced.
For freight operators, the practical effect is likely to be greater consistency through high-risk sections rather than major changes to overall route timing.
Pfeiffer said the combined changes aim to better align speed limits with current road conditions.
“The changes will provide greater speed limit consistency and smoother journeys for drivers on Bells Line of Road,” he said.
What other safety works are being considered?
Transport for NSW has also implemented additional safety measures along the route.
These include upgraded signage, updated warning signs, safer overtaking-lane merges, and new No U-Turn signage at the heavy vehicle safety station at Bell.
New town entry gateway treatments have also been installed at Bell, Bilpin and Kurrajong Heights in response to community feedback.
Those treatments are intended to better signal entry into village areas and encourage drivers to slow down.
Transport for NSW is continuing to examine further safety improvements, including realigned curves, safety barriers, improved signage and intersection upgrades.
