Question: How long is the motorway that Theydon Mount is close to?
Context: Provincial road 35-12 (Turkish: "İl yolu 34-12" ), named the O1-O2 connector (Turkish: "O1-O2 bağlantısı" ) is a 6.9 km long motorway in Istanbul, Turkey.  The motorway is a connector route linking the motorway O-1 (Istanbul Inner Beltway) to the motorway O-2 (Istanbul Outer Beltway), where it becomes the O-4 (Anatolian Motorway).  The route is one of two motorways linking the two beltways on the Asian side of the city, the other being the Şile Motorway. The R 7 Motorway (or "Ibrahim Rugova") is a motorway located in Kosovo .  Forming part of the E851, it is the first motorway constructed in the region and it links the Albanian border at the village of Vërmicë with the capital Pristina.  Construction of the motorway started in April 2010.  It was finished in 2013 with the Vërmicë-Pristina segment ending in Gjergjica at the M9.  The highway is seen as part of the larger Vërmicë-Merdar corridor ending at the Merdare border crossing with Serbia in eastern Kosovo.  R 7 is 101 km long at a cost of €824 million.  This highway, along with the A1 Motorway in Albania, have set the travel time from Pristina to Tirana to 3 hours.  Once the remaining E80 Pristina-Merdar section project will be finalized and completed, the motorway will link Kosovo through the present E80 highway with the Pan-European corridor X (E75) near Niš, Serbia.

The M25 or London Orbital Motorway is a 117 mi motorway that encircles almost all of Greater London, England (with the exception of North Ockendon), in the United Kingdom.  An ambitious concept to build four concentric ring roads around London was first mooted in the 1960s.  A few sections of the outer two rings were constructed in the early 1970s, but the plan was abandoned and the sections were later integrated to form a single ring which became the M25, aka London Ring Road, finally completed in 1986. Theydon Mount is a village and a civil parish in the Epping Forest district of the county of Essex, England, close to the M25 motorway.
