Orange cones have been placed along a left-turn slip lane bay at Anzac Ave, which flows on to the one-way-system in Castle St, NZTA Otago-Southland operations manager Roger Bailey said.
"We have been observing how it operates and there were an awful lot of people who weren't giving way to traffic and treating it like a free left turn, which was difficult for cyclists and other motorists."
A give-way sign was placed at the site when the cycle lane was first introduced along the one-way, "but the reality is a lot of people aren't giving away, and for some reason or another they are not seeing cyclists".
"If you sit and watch what is going on there, it is really scary," Mr Bailey said.
Following the death of cyclist Peter Wells (55) last November, NZTA had been approached by other cyclists "expressing ongoing concern with the close calls they have had at that location".
He confirmed NZTA was working on a permanent solution, "but in the interim the safest thing is to change the layout so that free left turn lane does not exist anymore".
In addition, a stop sign had been placed at the site, and "we are still working through a range of options to provide a permanent solution".
That might include creating a cul-de-sac for Anzac Ave, which would force traffic to go across the railway line, or down the main state highway.
NZTA would look how any changes affect traffic flow, and that could lead to a change in the phasing of traffic signals.
Affected parties, including the Dunedin City Council, and railway station and farmers market users would be consulted about any proposed change.
Asked about traffic using the front of the station as a shortcut, he said there was "anecdotal evidence that some heavy traffic is occasionally doing that".
"If we blocked off the intersection altogether we would not want to promote that route being used by general traffic. It is not a public road per se."
Another problem with the intersection was drivers who sat at the give way waiting for traffic to clear along the one way so they can turn into Stuart St.
With traffic banking up behind them, other motorists cut inside the left of them "ignoring the give-way sign ...it is quite unnerving to watch".
A permanent change was likely to take months.
