Wellington Airport has called for Let's Get Wellington Moving to ditch the idea of a pedestrian crossing on the main route to the terminal.
Consultation closes on Wednesday for a plan to install traffic lights, a crossing, speed bumps and speed restrictions of 50km/h on Ruahine St and 60km/h on Cobham Drive.
The crossing on State Highway 1 is designed to make it safer for walkers and cyclists, but Wellington Airport wants to see an overbridge built instead.
Chief executive Steve Sanderson said the changes will increase congestion and delays for 35,000 daily road users.
"Cobham Drive is a gold standard example of state highway and cycleway design. It is long and straight with four lanes, separated by a wide median strip, and the excellent new cycle path keeps walking and cycling separate from vehicle traffic."
