The Milford Road (SH 94) was closed today (28 Aug) from 5pm, after significant rain increased the avalanche risk.

The road is the only land access to Fiordland's Milford Sound.

NZTA said the road would likely reopen tomorrow morning, but only after it had been inspected and the avalanche risk reassessed.

Predicted snow tomorrow (30 Aug) could see the road reclose again in the evening, they said.
