Erosion along I-94 in Macomb County prompts ‘emergency’ action

Stormwater drain experiencing significant erosion with each rainfall, threatening freeway

Macomb County officials are concerned that heavy rainfall will cause more erosion at a stormwater drain than runs along I-94, which could potentially take out the freeway.

ROSEVILLE, Mich. – Macomb County officials are concerned that heavy rainfall will cause more erosion at a stormwater drain than runs along I-94, which could potentially take out part of the freeway.

Macomb County Public Works Commissioner Candice Miller said Monday that the department is taking emergency action to help prevent further erosion of a Roseville stormwater drain. Running parallel to westbound I-94 near Little Mack Avenue, the drain has recently seen significant erosion with each rainfall.

Officials worry that additional rainfall could cause more severe erosion, which could be tragic to the freeway’s infrastructure.

“We consider this an emergency,” Miller said.

The stormwater drain has essentially eroded up to the fence that borders it, inching closer to the freeway’s edge. Miller says the ground between the drain and the freeway is the “foundation for the road.”

“We are gonna fix it right away,” Miller told Local 4 on Monday. “This will be fixed within the week.”

Crews are expected on site this week to work on mitigating the erosion, potentially through the use of large rocks or boulders, or by redirecting the water. Officials say a more permanent fix will also be in the works soon.
