The Iowa DOT has a meeting scheduled later this month on six-laning I-35 through the rest of Ankeny, from where the southern 1st Street (former IA 931) ramps join/split to where the rest areas used to be. North of there, a short segment is six lanes as part of construction of the Northeast 36th Street exit that opened in November 2012.
This is a follow-up to the original announcement in December that the 1st Street exit would be turned into a diverging diamond interchange.
