The Grand Trunk Road is one of the oldest and longest roads in South Asia.  It was originally built to connect Agra with the town of Sasaram.  The road was extended westwards by the Moghuls, at one time reaching as far as Kabul in Afghanistan, and was later extended further by the British until it spanned a major portion of India.
