Nice to meet you again with your inspiring comments :(.
The Passeio Maritimo in the eastern part of Praia Formaosa leading to the tunnel simply did not exist last week. The tunnel may have been open for some time, but the Passeio has vanished at least the last 4 years.
I left the western part from Camara de Lobos and the eastern part to Doca do Cavacas untouched, but there existed a third route connecting the both via the tunnel.
I just removed there the part through the tunnel and inserted instead the deviation per Estrada Monumental because many people are unsure how to get around the closed tunnel.
If that route is disturbing you, you may delete it, I have no ambitions on that.
