Motorists in the Des Moines metro area will want to consider an alternative route as the Iowa Department of Transportation has announced work is continuing on the Urban Loop interchange in Urbandale. Officials with the Iowa DOT said in a news release that the entrance ramp from eastbound Iowa Highway 141 to Interstate 35/80 will close at 8 p.m. today. The east- and westbound exit ramps from the interstate to Iowa 141 will also close at 8 p.m. The ramp closures are part of a project to realign the ramps as part of the interstate reconstruction project between 100th Street and Douglas Avenue. The entrance ramp from eastbound 141 to I-35/80 is scheduled to reopen at the end of September. The other ramps are expected to reopen in October. According to the news release, the eastbound exit loop from I-35/80 to Iowa 141 will be replaced by an exit ramp from northbound I-35/80 at Meredith Drive and the new flyover exit from northbound I-35/80 to westbound Iowa 141, both of which are expected to open at the end of August.
