How the Nanjing Yangtze River Bridge changed China forever

In unstable cultural revolution era, they built the long bridge by themselves. It's the first surprising thing for us. The second one is that there were(are?) pedestrians' lanes on such a huge bridge.
I wonder if there were people who walked on the bridge as a commutation route in daily life.
