"1.2.4.3 Continuity Tendons
To complete a span, the ends of two adjacent cantilevers are connected by a cast-in-place closure at or near mid-span of interior spans. In end spans, the closure joint is usually nearer to the end expansion joint. When the closure concrete attains sufficient strength, longitudinal post-tensioning (continuity) tendons are installed, tensioned and grouted. Figure 1.13 depicts typical locations and layouts for bottom continuity tendons at mid-span."
