First I take off to the outside then onto one of the main roads that take me to the city limits. This is where a metro station is. Past it about some distance from it is the expressway. This thing is huge with more parallel underpass roads as it looms over them running almost in straight line on 4-5 lanes of elevated concrete, on each side to and fro the city. A green patched way on the extremes for pedestrians on foot. Automobiles zipping past me as I walk about 8 km of it. Air is clean, and even after the overwhelming volume of traffic on both sides, almost every few meters always filled with cars trucks bikes zipping past me, there is no noise just like water flowing. But there were moments when after border crossing on foot I would feel scared or if I got lost there.
