One of New South Wales' most historic roads is set for an overhaul, with the Australian Government committing $100 million for safety works on Bells Line of Road.

The funding will allow for safety upgrades, such as overtaking lanes, making for a safer journey for the thousands of locals and tourists who use the scenic route between the Blue Mountains and Richmond each day.

Stretching from Richmond in the east to Bell in the west, the road was heavily impacted by extreme weather in March 2021 and subsequent bouts of record rainfall.

This funding injection comes as Transport for NSW continues to undertake investigation and repair work following the damaging weather events.
