KCRG reports that Boyson Road at I-380 will be closed for weeks starting Monday. There does not appear to be a corresponding press release on the Iowa DOT’s site. KCRG says it’s for “20 working days” so that’ll be four weeks. After that, though, the northbound entrance ramp will remain closed.
Northbound I-380 traffic will need to exit at Blairs Ferry Road and southbound traffic will need to exit at Tower Terrace Road or go down to Blairs Ferry Road and turn around.
