Two people have been caught on camera riding e-scooters through Brisbane’s Airport Link Tunnel.

Cars can be seen passing the pair at 80km/h, more than double the scooters’ top speed.

The number of food delivery bikes travelling in the city’s tunnel network has also increased, with approximately nine riders picked up in an average month – double that of last year.

Transurban monitors the tunnel network 24 hours a day and dispatches an Incident Response Unit whenever a scooter or bicycle is detected.

Assisting the rider to safety often requires lane closures and traffic diversions.

The police are then called, with scooter riders facing a fine of $130 and cyclists of $133.

“They’re putting themselves in danger, they’re putting other people in danger,” Transurban general manager David McLoughlin said.

Incident response officer Brady Newell said he believed some people “don’t even realise they’re not supposed to be there”.

GPS routes have been blamed for directing riders onto restricted roadways, but there is also signage outside the tunnels indicating prohibited vehicles.

Lime today said its scooters set off an alarm when the scooter was parked incorrectly – but not when ridden incorrectly.
