SEP 2019Work to begin

Work to repair damage on the culvert (large drain) at Jounama Creek will begin in October 2019. Initial work will include establishing stockpile sites, temporary access tracks and ramps, and constructing a crane pad.

Work will be carried out from 7am to 6pm Monday to Friday and 8am to 1pm Saturdays.

There will be single lane closures at various times as the site is set-up.

Work periods will depend on water levels, weather and conditions.

The work is expected to be completed by mid-2020, however due to fluctuating water levels in Jounama Pondage, the project may extend into 2021.

Project information

The concrete slab on the culvert separating Jounama Creek and Jounama Pondage has been damaged, resulting in the slab separating from the culvert. The adjoining road embankment is also damaged and needs repair.

The damage is due to flood events in Jounama Creek since the culvert was built 50 years ago. Repairs are required to ensure further damage does not occur during flood events and reduce the` risk of emergency repair work closures on the Snowy Mountains Highway.

Construction is expected to start in October 2019. The work is expected to be completed by mid-2020, however due to fluctuating water levels in Jounama Pondage, the project may extend into 2021.

Features of the work include:

  • building an access track off the Snowy Mountains Highway
  • building site compounds for stockpiling of materials and equipment
  • building an access ramp from the compound into Jounama Pondage
  • removing the damaged concrete slab and loose material
  • extending the external culvert side walls
  • building a new apron slab
  • reinstating road batters.

The objectives of the work include:

  • providing a safe and available structure for all users
  • ensuring the long-term serviceability of the Snowy Mountains Highway and culvert structure
  • maintaining structural integrity of the culvert and embankment
  • providing timely repairs to minimise asset deterioration
  • being sensitive to the area’s natural environment, heritage and local communities.

A Review of Environmental Factors (REF) has been carried out to assess the likely impacts of the project on the environment and to detail the protective measures to be implemented.

The REF found the project would not significantly impact the environment. The safeguards detailed in the REF would avoid or minimise the expected impact.

Culvert repair work is expected to start later this year and will include removing the damaged concrete material, rebuilding a new concrete slab and extending the drain’s external side walls. Work will be carried out from 7am to 6pm Monday to Friday and 8am to 1pm Saturdays.

During this time, single lane closures may be required on Snowy Mountains Highway for short periods. The majority of work will be carried out with no major impacts to traffic, however speed restrictions will be in place during work hours.

Work periods will depend on water levels, weather and conditions.

The work is expected to be completed by mid-2020, however due to fluctuating water levels in Jounama Pondage, the project may extend into 2021.

Work at Jounama Creek will remove and repair culvert damage.
