MOTORISTS have used an online survey to slam Logan's congested roads, with the Mount Lindesay Highway and Middle Road copping criticism from angry drivers.
RACQ's Red Spot Congestion Survey asked drivers to highlight the worst points on the region's roads.
Motorists did not hold back, with the controversial Mount Lindesay Highway - where more four-laning upgrades began in mid-March - rating low.
Drivers said the road was poorly designed, with insufficient lanes for the number of cars and too many traffic lights.

An area of concern was the Green Road/Fedrick Street intersection at Regents Park, where multiple drivers say their journey was significantly affected.
Drivers reported 10 and 20-minute delays, with long traffic queues causing headaches.
"One lane each way for a major highway linking Beaudesert, Jimboomba and Brisbane," one driver wrote.
"Residential demand has outstripped the capacity of the road."
One motorist said it was a sub-standard highway with safety upgrades that have not improved traffic flow.
"Traffic [is] usually stopped back to Park Ridge in northbound lanes of a morning at around 7.30am, then stopped southbound to Middle Rd exit after 5pm," another wrote.
Logan MP Linus Power said the driver anger about the road was not news to him, but the government had secured money to battle congestion on the road..
"It's not a surprise at all," Mr Power said.
"I'm fighting every day for more investment on the Mount Lindesay Highway.
"We have had significant investment in four-laning on the Mount Lindesay Highway to reduce congestion."
"I'll keep being on the side of locals to get more sections of four lanes."
Drivers also criticised the Middle Road/Teviot Road roundabout at Greenbank, a junction Logan City Council's acting chief executive officer Silvio Trinca said was no easy fix at the March meeting.
Mr Trinca was answering Division 11 Natalie Willcocks, who said her roads were among the worst in Logan, and it seems her constituents agree.
"Roundabout carrying too much traffic," one motorist wrote of the junction.
"Too many people [are] trying to get home without proper infrastructure."
Another driver blamed the road design.
"[The] layout gives preference to vehicles from the west, meaning cars from the east take an eternity to turn left," the driver wrote.
"[Traffic] regularly banks up kilometres."
The nearby Stoney Camp Road intersection was labelled a hazard.
"Turning right from Stoney Camp Road into Teviot Road is dangerous," one driver wrote.
"The left turning vehicles block visibility to the left and busy traffic both ways."
