Which highway runs through both Round Rock, Texas, and Saint Paul, Minnesota?
Interstate 35 Interstate 35 (IH-35 or I-35) is a major north–south Interstate Highway in the central United States. I-35 stretches from Laredo, Texas, on the American–Mexican border to Duluth, Minnesota, at Minnesota Highway 61 (London Road) and 26th Avenue East. Many Interstate Highways formerly had splits or spurs indicated with suffixed letters (N/S/E/W), and I-35 was the only one that still had such divisions, before the recent opening of I-69C, I-69E, and I-69W in South Texas. In two stretches, both through twin cities, the highway splits into Interstate 35E—at Dallas and at Saint Paul, Minnesota—and Interstate 35W—at Fort Worth, Texas, and at Minneapolis.
State Highway 243 (Minnesota–Wisconsin) Trunk Highway 243 and State Trunk Highway 243 (MN 243, WIS 243) are two short state highways in the U.S. states of Minnesota and Wisconsin. They connect MN 95 in Franconia Township, Minnesota with WIS 35 in Osceola, Wisconsin. The two highways meet at the state line on a bridge across St. Croix River. The combined highway is 1.53 mi in length, 1.23 mi in Minnesota and 0.30 mi in Wisconsin. The two highways were designated in 1949. The bridge across the St. Croix River dates to 1953.
