AN estimated $7-$8 million will need to be spent on mitigating damage to the West Tamar Highway, according to yesterday's Parliamentary Public Works joint house committee assessment.
Evidence from the committee was presented at Henty House following an inspection of the highway.
A wider shoulder as well as a barrier separating single lanes from double would also be included, according to committee deputy chairman Western Tiers MLC Greg Hall.
''The issue with that bit of road is that it lies on a landslip area - there will be several mitigation measures in what they're doing to make sure the road has a full life of 20 years or so,'' Mr Hall said. He said the committee, comprised of Huon MLC Paul Harris, Bass Greens MHA Kim Booth, Braddon Liberal MHA Adam Brooks and Labor Lyons MHA Rebecca White, would release a report within the next few weeks.
``Some discussions are still in committee at this stage but a report will be produced as to what will transpire from our findings.''
