The new exit for IA 141 from northbound I-35/80, along with a half-diamond to the south at Meredith Drive, opened Friday. The Register had a preview earlier in the week. Presumably, northbound/eastbound, the Meredith exit will be 127A, and the 141 ramp will be 127B, as it splits right as the interstate goes under Meredith.
Here is a comparison of the area, 35 years apart (1984 and 2019), via Iowa Orthographic Server. You can also see the later additions of the 86th and 100th Street exits. Development along 141 outpaced state planning so it would not be easy to block off intersections and turn it controlled-access to the IA 44 exit.
The 2020 design takes out the inner loops at the curve, and those loops had been redone with the extension of Urbandale Drive.
The Register story links to an earlier one about the explosion of growth in Grimes, including the potential for THREE Hy-Vee stores. Meanwhile, Jewell and Edgewood had to resort to community efforts to stop their grocery stores from closing, and there is only one left in all of Calhoun County (Lake City Foods) because Manson and Rockwell City each lost theirs.
