Construct structure to carry relocated iron bridge RD. Over the up RR, construct two structures to carry up RR & interurban trail over woodside RD.

On May 5, 2025, the Federal Highway Administration awarded a Formula Grant totaling $7,787,231.42 to the Illinois Department of Transportation (IDOT) under the Highway Planning and Construction program (CFDA 20.205). This award funds the construction of three structures and a tunnel/underpass to facilitate the relocation of Iron Bridge Road over the Union Pacific Railroad, and the construction of two structures to carry the Union Pacific Railroad and Interurban Trail over Woodside Road.

The project scope encompasses comprehensive site preparation and infrastructure development activities including tree removal, earth excavation, embankment construction, storm sewer installation, culvert installation, retaining walls, and full-depth Hot Mix Asphalt (HMA) pavement with resurfacing and shoulders. The award also covers auxiliary infrastructure such as curb and gutter installation, sidewalk construction, concrete median construction, signing, pavement markings, guardrail installation, traffic signal deployment, and shoofly track construction to support temporary traffic management during construction. These improvements address critical transportation infrastructure needs in Illinois and reflect the Federal Highway Administration's commitment to supporting state-administered highway and multimodal transportation projects through the federal-aid highway program.
