The future Southwest Arterial and Swiss Valley Road interchanges planned on US 20 southwest of Dubuque will cut down, but not eliminate, at-grade intersections between the west side of Dubuque and Peosta.
There was a public meeting last month on the Swiss Valley Road exit, scheduled for construction in 2019-21. (Handout PDF, Map PDF) This exit is where 20 curves northward from its straight line across the county. The roadbed of the four-lane will be moved slightly and a batch of frontage roads created. Two intersections will remain east of the Peosta exit, but then none until Old Highway Road; another frontage road will eliminate the stoplight at Menards, the Telegraph Herald reported May 2.
