The Iowa Department of Transportation is overseeing nearly $980 million in highway improvement projects in 2026 to maintain the state’s interstate and primary highways. Central Iowa is expected to have over 100 construction and maintenance projects, including bridge replacements and rehabilitation efforts. The 2026-30 Iowa Transportation Improvement Program plans to invest about $4.3 billion in highway and bridge construction. Drivers are advised to practice work zone safety and use the Iowa 511 Traveler Information System for real-time updates on traffic and construction projects. Recent projects in North Iowa include resurfacing and paving on I-35 and completion of paving on U.S. 65 in Mason City.
