Amman has an extensive road network, although the mountainous terrain of the area has prevented the connection of some main roads, which are instead connected by bridges and tunnels. The Abdoun Bridge spans Wadi Abdoun and connects the 4th Circle to Abdoun Circle. It is considered one of Amman's many landmarks and is the first curved suspended bridge to be built in the country.Abdoun Bridge, considered one of Amman's landmarks
