DULUTH, MN (KDAL) - St. Louis County public works employees have repaired a large hole on the Ives Road north of Duluth and it has now reopened to traffic. The hole formed near an bridge abutment and measured two feet in diameter and around 5 feet deep. County engineers believe it formed due to a residual effect from last summer's flooding. It is a sample of how subsurface impacts take time to appear and more could pop up this spring. Public Works Director Jim Foldesi says this is a good reason why they are asking lawmakers for flexibility in how flood recovery dollars are allocated.
