Work to install barrier rail along westbound Iowa 141 north of Interstate 35/80 in Urbandale requires closing the east- and westbound I-35/80 exit ramps at the Iowa 141 Urban Loop (formerly Rider Corner) interchange from 7 a.m. to 5 p.m. on Saturday, Nov. 9, weather permitting, according to the Iowa Department of Transportation’s Grimes construction office.
The ramp closures are necessary due to the reduction of westbound Iowa 141 to a single lane between I-35/80 in Urbandale and 37th Street in Grimes. Significant traffic congestion on westbound Iowa 141 is anticipated with this lane closure, which would cause traffic to back up on the interstate exit ramps and onto the interstate, leading to unsafe conditions.
Entrance ramps from Iowa 141 to east- and westbound I-35/80 will remain open during this project. Motorists can follow a marked detour route (see map) during construction.
