Can anyone confirm that the bridge at 37Ac is "Bay"? I originally has "Bayou".

Sorry unclued, I have a complete grid but am hopelessly lost as regards the end game. I initially didn't come up with 'BAY' but had 'TUNNEL' instead. Tunnel bridges I know do exist but is not in BRB!! Cannot make any sense of the continuous path that is reqd. Anything connected with a Eulerian path?

The tunnel is the hidden method of making the solution possible. Without it there would never be a complete way round. Therefore you don't count the tunnel as a bridge - clever eh? Good luck!

Unclued, clever as you say ! Still a long way to go, and Listener 4210 imminent so time is a factor! Thanks all the same.

I don't think it's possible without crossing at all. I wonder if we're just banned from crossing on the thematic items, and from going back over them. The wikipedia analysis of the original puzzle reduces the problem to nodes (points) and connections between them ("edges"). The nodes are points (zero dimensional), hence the notion of "crossing" there doesn't arise.

I started at London and went via the tunnel to Tay, Humpback, Bay, Pontoon, Foot and Toll in thaqt order. Does anyone else agree?

The stuff in the preamble about lines being drawn from the CENTRE of cells at either end of the thematic items is there to allow a little bit of jiggery-pokery on the island. The original problem was not solvable with an odd number of items, so Merlin's additional crossing makes it an even number. You have to start ON the island, because the direction of travel on the items means you have to come off it three times and onto it twice. The finish has to cost you money, or there's no way to get to the harbour. You will need to put a curve or a kink in your line to get from the Scottish item, around the top of the one that is now in the USA, under the pedestrian one to the top of Quasimodo. I go CAPITAL, BORE, SILVERY, (2 TWISTS & TURNS) RICHARD III, HERB, CARD GAME, 12 INCHES.

The tour must start and finish in regions with an odd number of 'nodes' (ie bridge ends)and must proceed from the higher number (5) to the lower (3). The exact choice of route is dictated by the directions of travel across the bridges and the need to avoid a crossing path. That one of the objects is not a bridge is confirmed by the colour of the 'E' !!
