EYRE Peninsula livestock carrier David Smith, Tumby Bay, says it is farmers who are ultimately paying for the lack of B-double access to Lobethal.
He believes it costs them 5 cents to 6c a head extra in freight.
"We have been road train-capable for 12 years and B-double capable for even longer, but we still only load singles to Lobethal, which is just a joke in 2012."
Mr Smith's business delivers between two and five loads of sheep a week to Lobethal.
He says it is frustrating that he can freight animals up to 800 kilometres on a B-double. but cannot take them the last 20km.
Mr Smith will not consider unhitching the lead trailer at a parking bay near the Freeway and then delivering each section individually because of animal welfare and road safety," he said.
"We already have curfews for noise control at Lobethal so it (B-double access) is just another thing to contend with."
Mr Smith says those delivering lambs interstate on a B-double have logistical issues accepting jobs back to SA if lambs are destined for Lobethal.
He also questioned what happened when the abattoir's largest customer Woolworths suddenly needed extra lambs for a special kill to fill higher meat sales.
Ideally, the route would bypass as many towns as possible.
"We are satisfied the department is treating it seriously now and moving forward with it, but it is still a little way away," Mr Smith said.
