What is the "bridge" on a U-shaped desk?

The bridge is the third surface section on a U-shaped desk — the panel spanning from the return to close the U. Bridges typically measure 36"–48" wide and 24" deep. Some configurations use a credenza (lower surface with storage, 29" high) as the bridge; others use a standard-height bridge (29"–30") for a continuous work surface. A credenza bridge offers storage but sits slightly lower than the main surface. At OfficeFurniture2go.com, our listings specify bridge type clearly — call 1-800-460-0858.
