Iowa Highway 946 (Iowa 946) is a short state highway that provides a direct connection between U.S. Highway 61 (US 61) / US 151 and US 20 in downtown Dubuque. It was created in 1991 after the construction of an expressway made a direct connection between the two roadways impossible.
Route description
Iowa Highway 946's short route begins at an interchange along the US 61 / US 151 expressway. Northbound traffic passes beneath the expressway and joins southbound traffic on Locust Street. In the half-mile (800 m) between US 61 / US 151 and US 20, Iowa 946 passes a light industrial area. Iowa 946 intersects U.S. Highway 20, known locally as Dodge Street, at a signal-controlled intersection. Immediately east of this intersection is the approach to the Julien Dubuque Bridge, which carries US 20 across the Mississippi River into East Dubuque, Illinois. Iowa 946 continues north on Locust for 1,000 feet (300 m) through another light industrial area. At the edge of downtown Dubuque, Highway 946 turns east for 600 feet (180 m) where it meets US 61 / US 151 just west of Dubuque's Ice Harbor.[2][3]
History
Iowa 946 was created along Locust Street upon the staggered completion of an expressway starting in 1991 which relocated US 52, US 61, and US 151 away from Locust Street and closer to the Mississippi River. The new expressway carried the three routes beneath the approach to the Julien Dubuque Bridge, making a direct intersection impossible. Since all four routes are U.S. Highways and come from all directions, it was imperative to keep the routes connected. With the completion of the Southwest Arterial around the southern edge of Dubuque, US 52 was routed away from the downtown area.
Major intersections
The entire route is in Dubuque, Dubuque County.
