Maybe the wide divergence of opinion has to do with which part of the Camino Portugues each person is referring to. I think there are three typical starting points -- Lisbon, Porto, and the Spanish border (Tui). The camino experience, IMO, changes radically from Lisbon to Porto, Porto to Spain, and Tui into Santiago.
The most popular is Tui to Santiago. Albergues are well established, everyone knows about the Camino. On that section, at least according to one recent rant/commentary, the massification is such that it resembles the moving sidewalk of the Frances.

From Porto to Santiago, there is good pilgrim infrastructure, but probably it lags behind the growing crowds. Scroll down on the facebook page of the albergue de Ponte de Lima and you will see evidence of huge crowds. With its 60 beds fully occupied on a day in April, something that would have been unheard as recently as last year, I think, the camino between Porto and Santiago is experience a crush.

Still relatively untraveled is the segment from Lisbon to Porto. But if you look at the facebook page of the albergue in Mealhada, youºll see daily postings of pilgrims staying there.

My experience on the traffic is that though from Lisbon to Porto there is a lot of road walking, it is only VERY rarely on the side of major roads. And when it is on the side of major roads, the shoulder is very ample. From Porto there is a fear-inducing walk out of the city, but in general my experience was like Davroos´ but day and time of day could be huge factors as well.
Would love to hear about more recent experiences from Lisbon northward, bom caminho everyone. Laurie
