The Abu Dhabi Gate is commonly known as Al Salik. This is the single entrance to Abu Dhabi city. The Abu Dhabi Gate is a toll road that is located in Al Ain and Al Gharbia. This road is open 24 hours and allows you to pass through the city of Abu Dhabi. This is essential for taxi drivers who drive from Al Ain to Abu Dhabi. However, the Abu Dhabi Department of Transport has launched a new online payment system for its Darb toll gates. The new system is available online. This allows the users to pay the tolls without going to the gate. It helps in saving time and money.
