Just a note to record why I edited this article to make it differ from Domain Tunnel (5 Jan 2005).

We didn't actually finish the Burnley tunnel until December 2000 (as those who worked to dry out Swan Lake remember all too well).

The shallow river crossing (sheet-pile cofferdam, half the river's width at a time) was restricted to Domain tunnel. The roadheader on Burnley tunnel went deep under the river and wasn't troubled by the river at all.

The presence of the Yarra had nothing to do with the water ingress problems of the Burnley tunnel - that was all down to the pressures in the Silurian aquifer Burnley passed through. The water pressures were much higher than expected.

It's perhaps a wee bit unfair to say that the deepest parts of the Burnley tunnel still leak (five years after the last inundation). But I suppose under the circumstances (having opened a year late, under higher legal pressure than water pressure) it's still worth recording that the tunnelling engineers didn't come out of this one smelling of roses.

Do we really need separate articles for each of the Citylink Tunnels, can't they be merged with the Citylink article ? Andypasto 04:58, 14 April 2006 (UTC)
