is correct to classify Metrobus as
highway = service and
service = bus
instead of
highway = busway ???

Metrobus is dedicated lane for buses, intead of - highway=busway - I used - highway=motorway_link. is this correct ? I think that the bus lanes dont belong to Avenida da Boavista, they are independent lanes, and the image of showld reflect that.

This stret shows 2 names : "Rua de Eugénio de Castro" e "Rua de Fernando Pessoa" althou is is correct in the edition map

Is this a motorway link or already Avenida da Boavista ?

Av. Boavista layout of lanes changed
