What is Freeway?

Freeway is a limited and controlled access road without intersections and is also a part of the highway.

It is named as freeway because you don’t have to pay anything to use it, and it is free from stoplights, at-grade crossings, and intersections.

Traffic on the freeway moves faster as compared to the highway, but the speed limit is restricted between 80KMph to 90KMph. On the freeway, there are two to four lanes in each direction with a barrier in between.

Freeway connects the city outskirts and rural areas and, subsequently, to the highway.

They can be solely used for vehicular traffic and are not to be used by other means of transportation such as bicycles, hacks, carts, e-rickshaw, etc.

The central government operates them, and they only take care of all its maintenance concerning upgrades and repairs.

Freeway can be accessed through on-ramps and off-ramps as no intersection exists.

On Freeway, you can see the large signboards in green colours with destination details, i.e. kilometre left or what is the next upcoming destination, convenience services or restroom ahead, and other outdoor recreation.

All these are posted on the freeway sides or overhead gantries.
