The entrance to the tunnel from the River Irwell taken from Prince's Bridge. The upper structure is to allow vehicle access over the top; the tunnel proper starts further in.
The new Bloody Bridge will cross from the marked spot.
All the concrete will be faced in.

A boater's eye view of the approach to the deep lock from inside the tunnel (except that there will be 6 feet of water rather than a few inches!).
The gap on the right will allow boaters to disembark and climb up to work the lock.
