*** 27 August 2026 - Amendment W9127N26BA0240001 Bonneville Lock and Dam - Navigation Lock 1 Bridge Replacement*** This amendment inserts additional Government Furnished Information (GFI) as an attachment to the solicitation.
The file “Power Line Layout” is provided for the Contractor’s information.
The Government shall not be responsible for any interpretation of, or conclusion drawn, from the data or information by the Contractor.
Information provided should be field verified by the Contractor.
If there is a discrepancy between the solicitation plan set and the GFI, the solicitation plan set takes precedence.
The project consists of replacing the existing bridge with a new fixed bridge on a new alignment and to provide for partial demolition of the existing bridge.
The new fixed bridge will be a single-span steel girder bridge with a concrete deck.
The bridge width will be 34’4½” out-to-out, with two 11’0” travel lanes, two 2’0” shoulders, a 5’0” sidewalk, and the superstructure will consist of four (4) built-up steel plate girders.
The replacement bridge alignment is located immediately downstream of the existing bridge and, at its northern terminus, will fit entirely between the existing bridge and the Bonneville Power Administration transmission tower which is located to the south.
Approach roadways will also be constructed to tie into the existing roadway alignment.
The new fixed bridge will be located over the existing navigation channel and will provide an under clearance that is larger than is currently present under the existing bridge.

Official solicitation and documents
The full solicitation, any attachments, and the actual submission instructions live on the official listing, not on this page. Oppward summarizes public record data; it does not host or mirror the source documents.
Oppward is an independent service and is not affiliated with, endorsed by, or sponsored by SAM.gov or any government agency. This page is a plain-English summary of public record data; the linked source above is the authoritative listing.
How to bid on this
This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.
- Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.
- Read the full solicitation on the official listing above, especially the scope of work, not just this summary. Our guide to reading a solicitation walks through what to look for.
- Check the set-aside listed above and confirm your business actually qualifies for it before you spend time on a proposal. See our guide to set-asides if the category is unfamiliar.
- Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
