Rep. Nunn announced the funding this morning at Johnston City Hall alongside Mayor Paula Dierenfield, Johnston police and chamber leaders, and State Representative Eddie Andrews. “Johnston has been one of the fastest-growing communities in Iowa for more than a decade, and our infrastructure needs to keep pace,” said Rep. Nunn . “Anyone who drives Highway 141 knows these intersections were never designed for the traffic they carry today. This investment helps eliminate dangerous crossings, improves emergency response times, eases congestion for thousands of commuters, and better connects Johnston neighborhoods through expanded pedestrian and trail access. It’s exactly the kind of commonsense infrastructure investment that improves safety while supporting continued economic growth.” Rep. Nunn secured the funding through the FY2026 Community Project Funding (CPF) process. The City of Johnston will administer the federal award through the Federal Highway Administration grant process before the project proceeds to the Iowa Department of Transportation. The project builds a new grade-separated interchange at Highway 141 and NW Towner Drive, separating local and highway traffic to eliminate at-grade crossings and reduce vehicle conflict points along the corridor. The project also includes improved access management, right-in/right-out intersections, and new pedestrian and bicycle connections that will link Johnston neighborhoods to the region’s growing trail network. The federal investment is part of a broader infrastructure initiative that has already secured more than $12.8 million toward the project, including a local commitment exceeding $6.3 million. Additional funding is being pursued through a federal transportation grant. Preliminary engineering and environmental review are currently underway, with the project expected to be bid in fall 2026 and construction anticipated to begin in 2027. Local leaders praised the investment and its impact on the community. “This project represents years of planning and collaboration by the City of Johnston, Polk County, the Iowa Department of Transportation and our federal partners,” said Paula Dierenfield, Mayor, City of Johnston . “Today’s announcement is another important milestone in moving this critical project closer to construction. A huge thanks to Congressman Nunn for his efforts in obtaining this $500,000 Community Project Funding grant for the project.” “The future interchange will be a significant investment in the future growth in Johnston, we look forward to all of the potential benefits and new opportunities that will be created, with the opening of this new project,” said Elizabeth VanGundy, President, Johnston Chamber of Commerce . “Construction of the interchange will improve traffic flow in a heavily congested corridor while also significantly improving the safety of all the current and future residents who utilize the corridor,” said Dennis McDaniel, Police Chief, City of Johnston . “As Johnston continues to grow, we have to make sure our infrastructure keeps pace,” said State Rep. Eddie Andrews . “This investment will improve safety, reduce congestion, and help ensure families, businesses, and first responders can travel this corridor more efficiently. I appreciate Congressman Nunn for securing this funding and for continuing to fight for the infrastructure improvements in Washington that keep Iowa moving forward.” Photos from today’s press conference are available here . ### Office Locations Des Moines Office 400 Locust Street Suite 250 Des Moines, IA 50309 Phone: (515) 400-8180 Ottumwa Office 223 East Main Street Suite 1 Ottumwa, IA 52501 Phone: (641) 220-9641 Creston Office 208 W Taylor Street Creston, IA 50801 Phone: (641) 220-9093 Washington, DC Office 1410 Longworth House Office Building Washington, DC 20515 Phone: (202) 225-5476 Sign Up For Newsletter Updates Copyright Privacy House.gov Accessibility
