Burrill Lake Bridge - Princes Highway upgrade

Roads and Maritime Services has started construction on the new Burrill Lake Bridge on the Princes Highway, just south of Ulladulla. Construction of this $58 million project is expected to be complete by early 2018, weather permitting.

Burrill Lake Bridge

Updates and announcements

Work completed since construction began in April 2016 includes construction of the temporary work platform to safely build the permanent structure, bridge piling works, major earth works, drainage work, vegetation clearing and the installation of other environmental protection measures.   

Construction of the $58 million Burrill Lake Bridge upgrade remains on time and budget and is expected to be completed by early 2018, weather permitting.

Temporary new road alignment

Roads and Maritime carried out planned night work on Thursday 9 February. This included line marking in preparation for a temporary new road alignment.

  • The temporary new road alignment opened to traffic on Thursday evening, 9 February, directly adjacent to the highway.

Temporary closure of Dolphin Point Road at the Princes Highway

The northern end of Dolphin Point Road at the Princes Highway will be the location for a site compound and work area. This section of Dolphin Point Road will be temporarily closed to local traffic from late March 2016 until early 2017, weather permitting. This will allow for the safety of motorists and workers during construction of the project. For more information on the closure view the letter to residents (PDF, 225Kb).

Community update - March 2016

Key features

Roads and Maritime completed the detailed design for the project in September 2015. Key features include:

  • A 290 metre long bridge spanning the lake on a new alignment to the east of the existing bridge
  • Roundabouts on either side of the crossing to connect the A1 Princes Highway to local roads
  • A pedestrian and cycle path on the new bridge, connecting to new paths on both sides and linking to the Ulladulla cycle path
  • Pedestrian paths underneath both ends of the new bridge. There would be a total of five locations where pedestrians can safely cross the highway
  • The new bridge and highway would be higher than the future 1 in 100 year flood level and reduce the impact of flooding
  • Complete removal of the existing causeway and bridge
  • A southern foreshore park on the existing bridge approach.

Potential benefits

Roads and Maritime’s detailed design of a higher bridge to the east of the existing crossing would:

  • Improve the overall reliability of the Princes Highway on the south coast by reducing future maintenance issues
  • Provide a lake crossing and road approaches designed above the predicted 1 in 100 year flood level
  • Improve road safety by providing new intersections to modern safety standards connecting the Princes Highway to local roads
  • Provide improved pedestrian and cyclist access and safety.

Review of Environmental Factors

The review of environmental factors assesses the potential environmental, economic and social impacts associated with the proposed upgrade and recommends measures to minimise any potential impacts identified. The review of environmental factors also includes detailed information from specialist studies undertaken by Roads and Maritime to determine whether the proposal is likely to have significant effect on the environment. You can view the Review of Environmental Factors on the project documents page.
