State roads policy, objectives and investment streams

The State road network connects cities, major towns, rural areas, key ports and airports, it is used by over 370 000 people. The network is made up of 3 700 kilometres of road and 1 300 bridges and major structures. To replace the entire network it would cost about $7 billion dollars. The State of Our Roads report includes more information about the State road network.

To manage the network within a strategic framework, we have applied a five-tier State road hierarchy .

The Tasmanian State Roads Ten Year Infrastructure Investment Plan (the Investment Plan) is an important part of the state roads integrated asset management framework. The Investment Plan continues to be improved in line with international best practice standards.

The goal of the Investment Plan is to deliver sustainable, affordable and appropriate levels of service to our customers in line with the State Roads Infrastructure Service Policy and State roads level of service framework. Two primary factors determine the ability to provide this level of service:

  • a sustainable and efficient level of investment in state road asset maintenance and asset replacement
  • a highly disciplined infrastructure upgrade program that delivers outcomes at the least cost and which takes into account resulting increases in long-asset maintenance and replacement costs.

The diagram below shows the relationship between the Investment Plan, the state roads asset management system and broader policies.

Investment Plan chart

The Investment Plan consists of six investment streams to address strategic State road network challenges that we will respond to over the next ten years and beyond:

This Investment Plan will be reviewed annually to make sure it:

  • maintains its ten year time frame
  • reflects government policy objectives
  • reflects the best available demand, asset and financial modelling forecasts
  • continues to deliver customer levels of service in the most efficient way.
