Legacy Way Air Quality

Legacy Way Air Quality

Transurban Queensland operates the Legacy Way tunnel in accordance with conditions established by the Queensland Co-ordinator General.

Unvalidated air quality data for the Legacy Way tunnel is shown below. View monthly validated Legacy Way air quality reports.

 

In-Tunnel Air Quality

The In-Tunnel Air Quality graph displays the previous hour’s average, each hour, for:

  • Carbon monoxide (CO)
  • Nitrogen dioxide (NO2)
  • Visibility coefficient (K)

Data is plotted according to Australian Eastern Standard Time (AEST).

 
  • CO
  • NO₂
  • K

Note:

  1. Monitoring and measuring protocols for each criteria as set out in the PIARC guidelines, as current December 2009.
  2. 2. Carbon Monoxide (CO) may fluctuate when peak traffic congestion occurs (ie traffic flows are less than 10 km/h).
  3. 3. Visibility coefficient (K) may fluctuate with peak traffic conditions (ie free flowing traffic refers to a greater speed than 50km/hr).
