Pedestrian bridges exist in the various maps and can be added in the editor, but do CiMs actually use them? I just set up a series of lines on each side of the river so that the only way to interchange between the two lines was to cross the pedestrian bridge in the Berlin map. I watched the bridge and the lines for half an hour at high speed and no one ever stepped onto the bridge. No one moved between the two sides of the river. No one used the sidewalks that cross other bridges. Are the people unable to cross the bridges for some reason?
