About this opportunity
The U.S. Army Corps of Engineers Portland District seeks construction of a replacement navigation lock bridge at Bonneville Lock and Dam, with proposals due October 29, 2026. The procurement is set aside for Total Small Business.
Place of performance is Cascade Locks, Oregon. The project involves replacing an existing bridge with a single-span steel girder bridge featuring a concrete deck, 34 feet 4 inches out-to-out, with two 11-foot travel lanes, two 2-foot shoulders, and a 5-foot sidewalk. The new bridge will be positioned on a new alignment immediately downstream of the existing structure, fitting between the current bridge and an adjacent Bonneville Power Administration transmission tower. The north abutment will be a concrete stub with spread footing anchored into rock; the south abutment will employ concrete supported by drilled shafts. Work includes lead and asbestos removal, seismic hazard mitigation through partial existing bridge demolition, and phased construction to maintain critical vehicular access throughout performance. Environmental and seasonal restrictions apply. Barge crane lifting will occur in close proximity to high voltage power lines.
The contract performance period is 1,295 calendar days from Notice to Proceed to accommodate in-water work windows in 2029 and 2030. The NAICS code is 237310, Highway, Street, and Bridge Construction. Ground anchors and jet grouting contractors must achieve pre-qualification with the Contracting Officer, demonstrating at least three years of relevant experience. Contractors must use an IL-4 web-based Construction Management Platform for all project administration and document management, beginning within seven calendar days of Notice to Proceed. Site visits were held August 27 and September 15, 2026; participants required U.S. citizenship and REAL ID. Most recent amendments (through October 20, 2026) modified Traffic Control Plan requirements, quality control standards, concrete specifications, and as-built drawing references. Inquiries must be submitted via ProjNet-Bidsm at least ten calendar days prior to bid close.

*** 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. The north abutment will be a concrete stub abutment with spread footing anchored into rock. The south abutment will be a concrete abutment that is supported by drilled shafts. To mitigate seismic hazards, portions of the existing bridge will be removed as part of the bridge construction requirement. The existing bridge provides for critical vehicular access to the Bonneville project that must remain open for the entirety of the construction project. This will likely require the contractor to construct the project in phases. In
addition, lead and asbestos removal will be required as part of this requirement. Working within environmental and seasonal restrictions and barge crane lifting will be required in close proximity to a high voltage power line will also be necessary during performance of the required work.

*** 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. The north abutment will be a concrete stub abutment with spread footing anchored into rock. The south abutment will be a concrete abutment that is supported by drilled shafts. To mitigate seismic hazards, portions of the existing bridge will be removed as part of the bridge construction requirement. The existing bridge provides for critical vehicular access to the Bonneville project that must remain open for the entirety of the construction project. This will likely require the contractor to construct the project in phases. In
addition, lead and asbestos removal will be required as part of this requirement. Working within environmental and seasonal restrictions and barge crane lifting will be required in close proximity to a high voltage power line will also be necessary during performance of the required work.
