International Bridge plans summer projects

Fast facts:
- The Sault Ste. Marie International Bridge has several repair and painting projects scheduled for this summer.
- A bridge abutment repair project will use an innovative epoxy injection technique for greater efficiency and fewer traffic impacts.
- The International Bridge Administration (IBA) will also replace sliding bearings, apply epoxy bridge deck coating and paint several bridge components.

To address ongoing maintenance needs at the Sault Ste. Marie International Bridge, the International Bridge Administration (IBA) has scheduled several repair and painting projects this summer.

“After 56 years of aging, loss of sand through the abutment embankment and retaining walls is not out of the ordinary,” said International Bridge Engineer Karl Hansen. (more…)
