Traffic lights have not been ruled out by the New Zealand Transport Agency as a way to ease growing congestion on Kawarau Rd.
The critical arterial road between Kawarau Falls bridge and the BP service station roundabout has been slowing vehicles to a crawl this summer.
Congestion is acute in the 50kmh zone from the Lucas Pl roundabout, which leads to Queenstown Airport and Remarkables Park Town Centre, to the BP roundabout.
Each day, about 16,700 vehicles travel between the two intersections.
Otago-Southland highway manager Ian Duncan said the transport agency was aware of the ''considerable traffic growth'' in the area.
''We believe it's being driven by a combination of tourism growth plus increased construction activity in the Frankton Flats area over the past 12 months.''
''We are about to start gathering traffic and other data to build a better understanding of the current traffic flow situation and issues,'' Mr Duncan said.
''Over the next few months we will use this information to develop options to help ease delays motorist are currently experiencing, especially at peak morning and afternoon travel times.
''Traffic signals at the BP roundabout intersection could well be in the option mix.''
