Mr Anderson was driving a truck which collided with the side of the bridge on May 1, spilling part of its load.
He has been driving that section of road for 18 years, and over the past year, five days a week.
His accident is another to add to the list of 14 crashes at the bridge and its approaches in the past 10 years.
Now, he has had enough of what he feels is one of the worst pieces of State Highway 1, which he ranks alongside part of the Kaikoura coast road for danger.
"My mission now is to have the bridge changed and I will do everything in my power to see that happen," he said.
"Something has to be done now because it's so wrong. It is substituting human lives because they do not want to do it, particularly spend the money."
He plans to campaign to have the overbridge widened or, at the very least, part of the highway filled in and a level crossing created.
He also believes owners of the rail line should financially contribute.
"A level crossing would be far better than what is there now," Mr Anderson said.
On the night of the crash, he, his wife and 7-year-old son were in the Kenworth truck and trailer unit travelling south to Dunedin.
Usually, when he approaches the overbridge, he slows if another truck is coming and lets it clear the bridge so he can go a bit wider to clear the concrete wall.
"I don't like passing other trucks under the bridge, but it's hard to see [while] coming south because you come over a rise [at Bulleid Rd]," he said.
On this occasion, he slowed for another truck going north and then continued under the bridge. As he did so, he felt the truck lurch to the left.
There was: "A big bang, carnage everywhere and a look of shock on my wife's face". The cab and trailer hit the wall, spilling cargo on to the road.
His wife received serious head injuries and he a cut on the head but his son, asleep in the sleeper unit, slept on.
After he stopped clear of the overbridge, he went back and saw his truck had dropped into a strip along the edge of the seal, about three metres long and a tyre-width wide.
That dropped him on to the Armco guard rail, which lifted the truck up on its wheel nuts and pushed him into the wall.
Mr Anderson said the shape of guard rails had a tendency to pick trucks up on the wheel nuts and he understood Transit NZ was investigating that.
He had had a similar experience on Portsmouth Dr in Dunedin.
Insurance assessors had estimated the damage to his truck tractor unit, which he has owned for just over a year, at $120,000. That did not include damage to the trailers nor loss of income.
Land Transport NZ crash statistics show a total of 14 crashes in the past 10 years at the overbridge and its approaches between Bulleid and McLeod's Rds have been reported to police.
There have been no deaths or serious injuries and nine minor injuries.
Eight of all the crashes have occurred in the months of April, May, June and July over those years, with six of them between 3pm and 5.59pm.
Thursdays and Sundays were the most common days for crashes, with three occurring on each of those days.
Transit NZ regional network manager Murray Clarke has promised to try to push through changes to the highway at the bridge, acknowledging that Mr Anderson's accident had the potential to have been very serious.
