Slope stability
In 2008-09 the RTA continued to use a risk
management approach to deal with road slopes.
More than 30 slopes were remediated or repaired, and major
work was completed at Mulligans Bluff on the Gwydir Highway
where the highway has been closed to one lane for many years.
Other highlights included:
• Major stability work requiring a full seven-week closure of
Bulli Pass on the Princes Highway Bulli.
• Works at Kariong on the Central Coast Highway.
• Work on Putty Road.
• Planning of new slips on Lawrence Hargrave Drive.
• Start of works on Berkley Cuttings on F6 at Berkley.
• Investigative drilling to upgrade groundwater wells on
Mt Ousley.
Reducing the risk of rock falls: Stabilising a section of the slope
using shotcrete.
Culverts
During the year, the RTA further improved
management processes for culverts. A guideline
for consistent collection of culvert inventory and
condition was released in October 2008. Thirty accreditation
training courses were run, 498 inspectors were trained and a
State-wide inventory collection process began. At 30 June 2009,
15,244 culverts had been inspected out of an estimated 33,000
culverts across the RTA road network.
A guideline for culvert risk assessment was also published
in October 2008. An accredited training program for
detailed risk assessment will begin after the completion of
a trial to validate the risk assessment procedures. A culvert
management framework policy is being completed.
