The Last Bridge is the easternmost bridge built by the kings of Arnor upon the Great East Road. It marks the border between the barrens of the Lone-lands and the Trollshaws in the shadow of the Misty Mountains, where lies Rivendell, refuge of Elrond Halfelven.
As Strider led Frodo Baggins and his companions to Rivendell they crossed the Last Bridge, and there Strider discovered a beryl – an Elf-stone, or more specifically, an emerald – left there as a sign that friends had passed that way. Indeed, the mighty Elf-lord Glorfindel had left the stone, and later aided in the rescue of Frodo from the Nazgûl at the Ford of Bruinen.
