NW 17th Avenue Bascule Bridge Replacement

Project Overview

Located in Miami, Florida, this four-lane, two-span rack and pinion bascule bridge carries traffic over the Miami River. PCL submitted a low bid to Miami-Dade County for the rehabilitation project, including structural steel refurbishment, sidewalk and roadway grating replacement, concrete spall repair, structural steel painting with lead abatement, class V cleaning and coating, and mechanical and electrical work with span lock replacement.

Immediately after awarding the project to PCL, the client was forced to permanently close the bridge to vehicular traffic due to newly discovered bridge deterioration. In the wake of the client’s transportation emergency, PCL proposed transitioning from the current bid-build project with a defined scope to a design-build project. Our project team also proposed a solution to the aging structure that included replacing the approach-deck concrete, bascule span deck steel support system, and the bridge’s mechanical system. Granted approval for these changes, the project team worked three shifts each day to complete design, procurement, and construction in 210 days. This mitigated the impacts of the client’s emergency closure and providing a functional, structurally upgraded, bascule bridge.
