Monday, November 18 marks one of the last opportunities to comment on environmental impacts of a current plan to replace and expand the I-5 bridge from Portland to Vancouver. The Interstate Bridge Replacement (IBR) project is currently projected to cost north of $7.5 billion. As the project undergoes evaluation by the US Department of Transportation, the federal agency is reviewing a draft Supplemental Environmental Impact Statement (SEIS), a document required by the USDOT to analyze the benefits and potential consequences of the project.
