Great East Road

The Great East Road was a Dwarven road connecting Moria and the High Pass with Belegost and Nogrod in the Blue Mountains. It originally extended west into Beleriand, where it terminated at Thingol's halls at Doriath, and also extends east to the Dwarven mansions in the Iron Hills.
After the First Age, when Eriador became populated with Men, Elves and later Hobbits, it became one of the major roadways in Middle Earth. It crossed with the great South Road at Bree. It also passed through the Shire, near Hobbiton and Michel Delving.
The road was used by Thorin and Company on their journey from Bag End to Trollshaws, and from Rivendell to the High Pass and east over the Bruinen. There, they had to change course to the Elven Road. Aragorn decided against taking The Hobbits through the East Road, instead going into the Wild and through the marshes, although they drew near it when they scaled Weathertop.
