Abu Dhabi's Transport Department (DoT) has announced the implementation of a toll fee system effective 15 October.

The electronic toll fees will apply when crossing four toll gates on Sheikh Zayed Bridge, Sheikh Khalifa bin Zayed Bridge, Al-Maqtaa Bridge and Mussafah Bridge.

The toll fee will be AED4 for every pass during peak hours from Saturday to Thursday, and AED2 during off-peak hours, and on Fridays and public holidays. The peak hours are from 7am to 9am, and 5pm to 7pm.

The daily maximum fee for each vehicle is AED16.

"Vehicles will be identified by their plate number without having to stick a tag on the windshield," DoT said in a statement.

The new system aims to reduce traffic congestion and "raise the efficiency of the transport sector".

It also aims to encourage the public to use Abu Dhabi's public transport network, reduce the use of private vehicles, and encourage car pooling among employees of the same organisation or members of the same family.
