Before the end span of the new Pattullo Bridge—now known as the stal̕əw̓asəm (Riverview) Bridge—could behave as a cable-stayed structure, it relied on a carefully engineered system of temporary bracing. This article explores how those short-lived elements provided critical stability during construction, then disappeared without a trace.

Temporary works must do more than carry load—they must manage settlement, seismic demand, and constructability under real-world constraints. Part B of this article explores how the TP3 temporary tower was engineered to mitigate settlement, redirect seismic forces, support construction sequencing, and then be removed without a trace.

Temporary works play a critical role in building major bridges, yet disappear once construction is complete. This article explores the TP3 temporary tower that supported the Pattullo Bridge end span for six months, enabling construction to proceed before the stay cables were engaged—and leaving no trace once its job was done.
