The decision to three-lane Whitiora Bridge was a political decision (link) that has not benefited Hamilton’s transport network. The third car lane is there to give cars a preserved benefit. The actual number of cars crossing would be the same if it still had two standard-width lanes with cycle lanes each side. The narrowing of the west-bound lane on the eastern end reduces the number of cars a lane can move (
Totally support a change back to two car lanes + cycle lanes (hopefully protected) & walkways.
