  The Humber Bridge Board said it hoped to submit a planning application by the end of the month.
  If approved the new centre could be open at the end of 2017.
  The proposal would see visitors travelling under the bridge in a glass gondola before changing to a glass lift to ride to a platform on the top of the North tower.

  Bridge Master Peter Hill said the scheme was about "making the best of what we've got".
  "People have for years had wanted to get more access to their bridge, so we're going to make it happen, " he said.
  Mr Hill said the project would be financed by the bridge board but "would not be funded from bridge tolls".
  A public exhibition of the proposals has gone on display at the bridge.
