Traffic Impacts

Motorists can expect lane closures on I-35 between 5th Avenue West and 21st Avenue East starting in July. Work will also require ramp closures on Lake Avenue and Michigan Street in late summer.

2025 work will reduce I-35 to one lane in each direction and require 5th Avenue West ramp closures.
