Bali Mandara Toll Road or Nusa Dua-Ngurah Rai-Benoa Toll Road is a toll road carried by a bridge stretching across the Gulf of Benoa. The 8.3-kilometre (5.2 mi) highway connects the city of Denpasar and South Kuta, Badung Regency, Nusa Dua and Ngurah Rai International Airport. It cost Rp 2.48 Trillion to construct and was intended to prevent traffic jams on the Ngurah Rai Bypass Road, previously the only road connecting areas of Bali on opposite sites of the airport. The Ngurah Rai Bypass Road, a land-based route, could not be widened because of the location of the airport runway; the new toll road was instead constructed over water.
