Abstract: Bridging is provided for use in joining joists or like construction elements so as to increase the strength and stability of those elements. The present invention utilizes flexible strapping to create the bridging structure, wherein a first flexible strap is attached to a first joist and a second flexible strap is attached to a second joist.
