Traffic Impacts

Beginning July 8, motorists can expect lane closures from 5th Avenue West to 13th Avenue East. The southbound I-35 off-ramp to Lake Avenue bridge and the northbound I-35 on-ramp from Lake Avenue bridge will also close July 8 for about one month.

In August, ramp closures will be required at Lake Avenue/Michigan Street on southbound I-35. There will also be lane closures from 13th Avenue East to 21st Avenue East.

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