On the bridge like this (Diego Valeri)

I've been thinking about Diego Valeri's wonderful poem about a bridge...and wondering if he had a particular bridge in mind when he wrote the poem?

Here is a photo of the elegant iron bridge, the Ponte dei Conzafelzi, over the Rio della Tetta near the Palazzo Tetta in Castello.  It was built in 1852 by the Collalto foundry at Mestre. 

I'd love to know the meaning of the word 'Conzafelzi' - can anyone assist?

On the bridge...like this...by Diego Valeri

E così mi son fermato
ai piedi del ponte.
E così ti sei fermata anche tu
un gradino più su.
Non sapevo ch’era un addio.
L’ho saputo un attimo dopo
sentendo le tue labbra sfiorare le mie.
Era la prima, era l’ultima volta.
Così.

And so I stopped
at the foot of the bridge.
And so you stopped too
a step up.
I did not know that it was a goodbye.
I knew a moment later
feeling your lips touch mine.
It was the first, it was the last time.
Just like that.
