IL 178, Repairs to Structure 050-0096 over the Vermilion River

The Illinois Department of Transportation, District 3 office, is planning to make repairs to the bridge, SN 050-0096, that carries IL 178 over the Vermilion River at Lowell.  Repairs include replacement of expansion joints, deck patching, latex concrete deck overlay, substructure concrete repairs, fiber wrapping of deteriorated beam ends, and acrylic coating of exposed concrete repairs below the bridge deck.  The acrylic coating will be tinted to match the color of the existing concrete as closely as practical.  The purpose of the repairs is to preserve the structure and extend its useful life.

The bridge has been determined eligible for the National Register of Historic Places and public input is being sought regarding the proposed repairs.  The Department is coordinating the repairs with the Federal Highway Administration and the State Historic Preservation Officer  in accordance with the processes of the National Historic Preservation Act of 1966 to minimize potential adverse effects to the historic character of the structure.

The Department is preparing environmental documentation supporting a Categorical Exclusion (CE) for the project in accordance with the National Environmental Policy Act of 1969.

All interested persons are invited to view the project website and provide comments.  The project team will respond in writing to all comments received.

Please provide comments by January 11, 2021 for inclusion in the environmental documentation process.

Persons who wish to provide comments or ask questions and persons with a disability planning to participate, who are in need of special accommodations, should notify Mr. Dave Alexander of this office.  Email David.s.alexander@illinois.gov, write to the Illinois Department of Transportation, 700 East Norris Drive, Ottawa, Illinois 61350 (fax 815-434-8951) or telephone 815-434-8468 (TTY 800-526-0844, Voice Users 800-526-0857) to provide comments, ask questions, or so that reasonable accommodations can be made.

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.

 

Proposed repairs include replacement of expansion joints, deck patching, latex concrete deck overlay, substructure concrete repairs, fiber wrapping of deteriorated beam ends, and acrylic coating of exposed concrete repairs below the bridge deck. The acrylic coating will be tinted to match the color of the existing concrete as closely as practical. The purpose of the repairs is to preserve the structure and extend its useful life.

Under the resources tab you can view the proposed fiber wrap and concrete repair locations for the IL 178 bridge. There are also photos of latex overlay and fiber wrap with acrylic coating placed on other structures in the area to give an idea of what the repairs might look like. The acrylic used on this project will be tinted to match the existing concrete as closely as practical. Original construction and major repair plans for the existing bridge are available under the resources tab as well as the structure summary, which provides recent data, dimensions, and ratings for the existing structure.

The purpose of the repairs is to preserve the existing structure and prolong its useful life by slowing future deterioration.
