A small section of County Road 91 is known as 40th Avenue West. Haines Road serves as an arterial route between West Duluth, Hermantown, and the Miller Hill area of Duluth. As of 2011, the section of Haines Road between Morris Thomas Road and Skyline Parkway carries approximately 7,000 vehicles per day, on average. A $12 million reconstruction project of this section of roadway began in September 2012 and was completed in October 2013. Crews added curb and gutter along a newly constructed roadway, which should help prevent the kind of washouts and mudslides that left sections of the roadway temporarily closed after the June 2012 Duluth flood. This section of Haines Road now has wide shoulders, two uphill lanes, a wider downhill lane, and a sidewalk. A 300-foot-long culvert along Merritt Creek was also installed. During the 2012–2013 reconstruction project, the roadway's notorious hairpin "horseshoe bend" section, as locals call it, on the 40th Avenue West segment of County Road 91, was straightened some, but could not be eliminated because of the steep nature of the hill, and the lack of additional funding that would have been required for an expensive project of blasting rock on the hillside. County Road 92 runs from the intersection of County 92 / U.S. 169 / MN 73 at the northeast side of Hibbing and continues east to its eastern terminus at the intersection of County 92 and County 25 in Cherry. The route is 8 miles (12.87km) in length. County Road 93 runs from the intersection of County 93 and U.S. Highway 53 at Central Lakes and continues east to its eastern terminus at the intersection of County 93 and County 16 in Makinen. The route is 6.7 miles (10.78km) in length. County 93 is sometimes used as a shortcut between U.S. 53 at Central Lakes and County 16 at Makinen to reach Palo and Aurora (via County 16 and County 100). County Road 100 runs from the intersection of County 100 and County Road 4 near Makinen and Palo and continues north to its northern terminus at the intersection of County 100 and State Highway 135 (MN 135) in Aurora. County 100 passes through Palo. The route is 12 miles in length.
