ITD Projects Southwest Idaho Idaho 55 Lardo Bridge

Lardo Bridge

Project Number: A013(392)

Project Key Number: 13392)

Project Description:

The 82-year-old Lardo Bridge on Idaho 55 at milepost 145 near the McCall City Park on the southwest shore of Payette Lake is scheduled to be replaced starting in 2014.

The department is developing a conceptual design that maintains McCall's character, protects natural resources and preserves scenic amenities.

When completed, the project will:

  • Replace the existing Lardo Bridge, built in 1931
  • Replace roadway approaches to the bridge
  • Provide bicycle and pedestrian facilities on both sides of the bridge
  • Serve as a gateway to the city of McCall

The new bridge will accommodate one lane of traffic in each direction. The existing bridge is 200 feet long and 38 feet from one outside edge to the other. The new bridge will be approximately the same length, but may be up to 50 feet wide.

ITD will use a design-build method for this project. Design-build is a streamlined process in which the design team and construction team work together simultaneously. This method allows for innovative methods of construction and results in quicker project completion. Lardo Bridge is only the second design-build project in Idaho.

Final bridge design will be completed by the design-build contractor. ITD will require the design-build firm to comply with the City of McCall Design Guidelines, include provisions for City-led public art on the bridge, include a viewing platform on the north side of the bridge, and provide outlets for holiday and other lighting.

The design-build contractor is selected on “best value,” which evaluates the team’s qualifications, technical proposal, project delivery, construction time and cost.
