HiG will never answer this.
As per usual now, the expansion is designed to work with the base game only, and they'll not clarify any interactions with other expansions.
I personally would say bridges and tunnels count as continuation of the road. And the road must go in the appointed direction on the next tile, so a straight bridge counts only for the straight arrow, and tunnels don't count for anything, as the road doesn't continue directly in the direction of the signpost (unless you place your second token on the same tile)
Maybe this is a job for Super Merpledrone to the rescue!! He will do the job that HiG won’t do. HiG live in a simply basic game rules for less headache….

OK. I've been working on these two images to illustrate those cases beyond regular roads...
The rules assume the signpost condition is met if a road segment connects the edge of the signpost to the required edge on the adjacent tile. If the road segment ends on the tile before touching the required edge or does not touch it at all, the signpost condition is not met.
The following image shows examples meeting the signpost condition (case A below) and not meeting it (case B). Case B shows a straight road (dotted in white) that ends at a feature on the tile (yellow circle) so it does not continue to the opposite edge (section dotted in black), and a curved road (dotted in white) that doesn't meet the signpost requirement (dotted in black).
In general terms, the road segment must connect the required edges to meet the conditions, but this connection may happen to include other features that provide this connection on the tile beyond a simple printed road on the tile.
Roads may include a number of features affecting them and even modify their layout at times. The rules cover roundabouts (see case A below). For other features, the same logic should apply also covered in the image below:
* Tunnels without tunnel tokens (case B) and with them (case C).
* Ferries (case D)
* Bridges (case E)
Case C (right) may present many variations when not meeting the sigpost condition:
* The signpost road enters a tunnel and exits on the same tile but not reaching the required edge (the case presented in the example)
* The signpost road enters a tunnel and exits on another tile (the second tunnel token is placed on another tile)
including those where the tunnel entrance connected to the signpost has no tunnel token or the exit tunnel token may be placed on another tile, if any
* The signpost road enters the tunnel but it may not exit (no tunnel token on the entrance or no second tunnel token to match it)
The labyrinth (case F, left) would always meet the signpost condition, the same as the 4-legged roundabouts in Exp. 7 or the Spiel '18 tile. The abbey tile would never meet the condition (case F, right), the same as any edge with a city gate.
Any thoughts?
