Waitaki Mayor Gary Kircher said there was ''considerable concern'' about the recent placement of rumble strips on State Highway 83.
He met NZ Transport Agency officials last week to discuss the concerns ''particularly between Otematata and Omarama at the moment''.
''Our concern is that you'll have some people that may or may not be confident on bikes travelling along that road, and potentially vehicles travelling both directions at 100kmh, and the risk is there,'' Mr Kircher said.
''And we believe that generally rumble strips are good at lowering risks, but that in some places they are increasing the risk for cyclists because they are pushing cyclists on to the road, where there is not necessarily good visibility.''
He said the council wanted the rumble strips gone ''in some places''.
A transport agency spokeswoman said the agency's cycling safety staff had ''a constructive discussion'' with Mr Kircher and other Waitaki District Council representatives.
The agency had asked Mr Kircher to identify specific locations ''where he felt there were issues, so we could investigate these''.
''Once we've got that list, we can look at what the next steps might be,'' she said. ''It's important to note that rumble strips offer significant safety benefits which can save lives and reduce the risk of a serious crash, and we need to balance the needs of all road users in making improvements.''
NZ Transport Agency system manager Graeme Hall said installing rumble strips was part of the agency's programme of low-cost safety improvements on regional state highways across New Zealand.
''On lower-volume rural state highways, more than 50% of deaths and serious injuries from crashes are as a result of run-off-road crashes, followed by head-on crashes, 30% in total.
''Rumble strips give drivers a wake-up call if they stray across the line, and can reduce all crashes by around 25% and fatal run-off-road crashes by up to 42%.
''By helping drivers stay in their lane, rumble strips reduce the risk of them driving along the road shoulder and crashing into a cyclist from behind. This is also the case on left-hand curves, where some drivers cut corners.''
Drivers might have a ''short wait'' at times before being able to safely pass cyclists, but the agency had put in rumble strips only on roads with ''lower levels of traffic'', to avoid significant delays.
''In places where there is very little road shoulder, we have put rumble strips to the left of the edge line, so cyclists have as much as room as possible.''
Mr Kircher said the council was soliciting feedback from cycling operators in the area, as they would have insight into users' experiences.
''The Omarama Kurow area, there's some challenging topography there and we want to make sure that we get this sorted out as best as we can.''
He said the agency could also play a role in helping the council complete the work to take the Alps 2 Ocean trail off the road entirely.
''That's our longer term goal, but if they can help us get it done in the medium term ... that would obviously be better for everyone and obviously improve the Alps 2 Ocean experience that much more.''
The trail of more than 300km, from Aoraki Mt Cook to the coast at Oamaru, is roughly 50% off road at present.
