May 7, 2006: This loop ramp from eastbound I-80/northbound I-35 to IA 141/Urbandale Avenue will be removed by the end of the 2010s.
KCCI reports that the Iowa DOT last week selected Alternative 2 for the IA 141 interchange at I-35/80. (That’s Rider Corner, not Ryder, where the interstate turns from north-south to east-west.) The selection comes with a 500-page, 25-megabyte (!) PDF about it.
A diamond interchange will be built to the east, at NW 100th Street, and two ramps will be added to the south, at Meredith Drive (northbound off/southbound on). As for IA 141 itself, the folded diamond/parclo will be removed. The westbound off/on ramps will remain substantially the same, but the northbound ramp will become a flyover ramp with bridge. However, there will not be any ramp from southbound 141 to eastbound 35/80; traffic will have to make a left turn at the stoplight at Grimes’ 37th Avenue half a mile north of the interchange and then a right turn onto 100th Street to that new interchange. Alternative 2 also adds a lane to most of each side of the interstate between Douglas Avenue and 86th Street, but as a non-merging onramp lane that becomes exit-only, not a through lane.
All the work on this interchange, the east end of IA 141, would occur later this decade.
