The entry of two-wheelers is banned inside the tunnel and they have to take Ghat Ki Guni route to reach NH-11, the Agra bypass, from Jaipur city.
Earlier, the Ghat ki Guni route was used by all vehicles for getting onto the highway from the city.
The route used to be accident prone and therefore the tunnel project was undertaken by the state government.
