Construction of the new I-69 mainline in Johnson County is reaching a halfway point. Over the coming month, State Road 37 traffic is expected to shift onto more than four miles of new pavement between S.R. 144 and Fairview Road.
The traffic shifts are expected to occur in four steps, starting this Wednesday. Northbound traffic will be reduced to one lane north of Banta Road and should expect delays between 8 a.m. and 5 p.m. S.R. 37 traffic is urged to slow down and stay alert for the changing traffic patterns.
Between each of the four traffic shifts, crews will move temporary barriers and adjust pavement markings to safely shift traffic to the other side of the road with both directions crossing the center median in between.
This will allow I-69 Finish Line crews to complete the mainline pavement and bridges. To view a map of the pavement surface for each section of the project, visit our Maps webpage.
