Hi Carlos,

When you take the graphhopper routing, it does use the tunnels. The only 
thing not 100% correct I could find is that a lot of roads still have 
construction=trunk on them (as well as highway=trunk). If it is still 
under construction you use highway=construction+construction=trunk, when 
the road opens you have to remove the construction=trunk. Maybe OSRM 
gets put off by that?

I've removed construction=trunk from all roads that have highway=trunk. 
See if that solves it.
