They say someone will die if something is not done to improve safety on the road.
But the New Zealand Transport Authority says people need to remember it is a state highway and the main road to the province's main port.
And while narrow and busy, it is not congested, nor does it have a large number of crashes compared with state highways in other parts of the country.
Neither the authority nor police say they are aware of, or concerned about any major problems with either the road's surface, or the way it is used, despite residents' concerns.
However, the authority says it has run tests to check speed limits are appropriate (it was happy with the 80kmh speed limit, but has reduced the advisory speed on the corner to 65kmh) and will check the camber of the road while waiting for the police report onlast week's truck-trailer crash.
If that report comes back with concerns about the road, it will investigate further.
Since the crash - in which emergency service workers said it was "a miracle" no other road users were injured as the trailer overturned and logs were splayed along 40m of the road at St Leonards - residents have expressed their concerns in the Otago Daily Times and on its website about the dangers they believe the corner presents.
Contributors expressed concerns about logging truck density, loads and speeds, the camber and general state of the road, and questioned why there could not be a return to rail for transporting logs.
Clare Ridout, from the nearby Dunedin Rudolf Steiner School, summed up several contributors' arguments when she said that stretch of road had become "frighteningly dangerous" because of the volume of logging trucks,Long-time truck driver Wayne Laurie said if there was a cyclist, a car was parked on the side of the road, or a car coming from the opposite direction was over the centre line, there would be little leeway for truck drivers to move without hitting a bank or crossing the centre line.
NZTA Otago coastal area manager Roger Bailey said SH88 was narrow and busy and a "big glut" of logging trucks was using the road.
Having so many residences close to a state highway was not an ideal mix, "but we have to live with it", he said.
Moving or altering the road was a matter of priorities and economics.
Everyone always wanted speed limits reduced, and they were reviewed every year, but that, too, needed to be balanced against the efficiency of moving traffic.
Senior Sergeant Steve Larking, from highway patrol, said police recognised SH88 was a narrow, busy stretch.
With more traffic, it was more likely more crashes would happen.
Police carried out regular speed operations and a static speed camera operated, but the road was not identified as a particular problem.
