M10 Motorway (Enderron)

The M10 Wentworth Orbital Motorway (locally referred to as The Ring Road or The Ten) is a ring motorway encircling Wentworth Metropolis, Enderron. It is one of the most important and busiest roads in the country. It opened in sections between 1967 and 1991. The road encompasses four constituent motorways, each comprising a 'side' of the ring: the Hounslow Expressway (north), Federal Motorway (east), Castlebrook Motorway (south) and Inner West Bypass (west).

Plans for an orbital ring motorway around Wentworth were first proposed after World War II. The first section of what today comprises the M10 to open was the Federal Motorway on the eastern side of Wentworth, which opened in 1967 but was not considered part of the orbital route at the time, but rather an extension of the M1 Motorway. The M10 designation came into existence in 1972. The northern east-west section, the Hounslow Expressway, opened progressively throughout the 1970s between the northern suburbs of Wentworth and the newly opened Wentworth Bexley International Airport. The Castlebrook Motorway, which is carried by the Castlebrook Bay Bridge, opened in 1986. The two sections were linked up by the Inner West Bypass in 1991, completing the ring more than 24 years after the first section was completed.
