From
construction of the sandstone bridge, many little stores, named " obradors",
for selling of various products were built on the roadway. In XIVth century, they
were so numerous that, in 1333, an order must regulate their number. The land
register, in 1403, counted around twenty put on the two side of the bridge.
In
XVIth century, the bridge threatens to collapse and it was decided to reinforce
it building retaining arches
(2) under
original arches (1).
In 1699 it was decided to widen the roadway making corbelled arches (3)
to allow saving 35cm space. To day, these corbelled constructions still support
parapets.
