• Complete separation of opposite moving traffic
by a divider or median

avoided
• Telephone facility, Highway Police, Servicing
Stations, Refreshment Facility available at regular
intervals
9. • Heavy Traffic with high speed (120 Km/Hr.)
• Land width= 90 m.
• Connects major points of traffic generation
• Slow moving traffic is not allowed
• No loading unloading and parking allowed
• Full Access control
10. Arterial Streets
