National Highways in Goa are among the narrowest in the country and will remain so for the foreseeable future, as the state government has received an exemption that allows narrow national highways. In Kerala, highways are 45 metres (148 feet) wide. In other states National Highways are grade separated highways 60 metres (200 feet) wide with a minimum of four lanes, as well as 6 or 8 lane access-controlled expressways.[116][117]
