 Since the beginning of the 21st century, Iowa DOT has continued to widen US 30 to four lanes. In 2004, an $ 18.6-million (equivalent to $ 28.1 million in 2016 dollars), four-lane section opened from east of Marshalltown to the Meskwaki Settlement west of Tama, bypassing Le Grand. In 2010, two sections of expressway were completed. A seven-and-a-half-mile-long (12 km) section from Colo to State Center opened to westbound travelers on November 29, while the eastbound lanes opened a week later. The seven-and-a-half-mile-long (12 km) section, which bypasses the Tama / Toledo area, opened in two segments. The first of which opened on November 1, and the second on November 25. On July 7, 2011, a section from State Center to Iowa 330 opened in Marshall County. This created a four-lane expressway from Ogden to Tama, covering 75 miles (121 km).
