KeithlKen,
Our approximated costs for the two bridge options are on the attached excel file. These unit costs are based on
average bids from recent projects and the assumption that shale extends 50' below the roadway. I added the
15% contingency to cover items such as grading, riprap, lighting, pavement marking, etc.
Let me know if you have questions or comments.
Thank you,
Madonna
