The US 218-C57 (Cedar Wapsi Road) interchange opens today, the Iowa DOT says in a press release. The opening comes a month after the ribbon-cutting ceremony.
Also today, the three at-grade intersections with US 218 between Cedar Falls and Janesville will close permanently; they were right-in-right-out intersections as an interim move. This means that old 218 on the north side of Janesville will be the last intersection on 218 heading south until you get southeast of downtown Waterloo and all traffic will get on/off at C50, C57, or Lone Tree Road between Janesville and Cedar Falls.
