In physical terms, the length of the road could not be described. No one can see the destination. If it were attached physically to this world, it would be possible to see the end. We could follow it by plane until we saw the end. It might be described in time. It has been traveled for thousands of years. People reach the city of Destruction one at a time when they die. Every day, people, tens of thousands of them, disappear from the road; they die. However, the road is so crowded that the dead are not missed or, if so, only for a short time. The destination does not seem to be the object of the people on the broad way. They are just pleased with the road, their companions on the road, and the pleasures of the road.
Jeremiah 17:7-8: "Blessed is the man that trusteth in the LORD, and whose hope the LORD is. For he shall be as a tree planted by the waters, and that spreadeth out her ROOTS BY THE RIVER, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit."
