Traffic Impacts

The 5th Avenue West to I-35 northbound onramp is currently closed to allow for crossover construction in preparation for 2025 work on the I-35 mainline bridges. Left lane closures on both northbound and southbound I-35 between 5th Avenue West and Lake Avenue will continue for this work. Crossover construction is expected to be complete by late October.

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