Traffic remains blocked on Sainte-Catherine Street between Guy Street and Saint-Mathieu Street as crews continue to repair a ruptured pipe.

Ville-Marie borough officials say it could take crews anywhere from four to 10 days to repair aging sewer pipes that broke near the intersection of Sainte-Catherine and Guy streets yesterday.

A part of Sainte-Catherine Street West was first blocked off Wednesday as maintenance workers tried to replace a 128-year-old sewer pipe made of brick.

The Ville-Marie borough said workers have had to dig a hole in order to access the old pipe which had collapsed.

"We're trying to do it the fastest we can," said Réal Ouellet, the crew's surpervisor.

While working on the original rupture, crews discovered a large hole where another sewer pipe should have been.

Borough officials said they are unsure whether this second pipe had previously collapsed or what has become of it.

A portion of Pierce Street is also blocked off between Maisonneuve Boulevard West and Sainte-Catherine Street West.
