Border between Spain and Portugal

Hi all,
I noticed that using OSM (web) with cycling profile to go from Ayamonte (Huelva, Spain) to Vila Real de Stanto Antonio Algarve, Portugal),
OSM illustrates an absurd and very long route, while there is a ferry service across the river(Rio Guadiana) in an hour to $ 2 only. The ferry operates from 15th June to 15th September.
Who can fix this anomaly? I unfortunately can not.
Thanks,
Sonia from Italy.

I’d suggest posting a link to the route that you get (just copy the URL).

I’d also suggest asking somewhere that’s a bit more high volume than this forum, which seems to have had one post in the last month. https://help.openstreetmap.org/ is a general help site that is higher volume.
