CHATTANOOGA (Times Free Press)-- The restored Market Street Bridge, the largest drawbridge of its type east of the Mississippi River, is expected to pick up a new honor in coming weeks — a spot on the National Register of Historic Places.

The bridge, opened in 1917 after three years of construction, is still a working drawbridge and is among 10 Tennessee sites up for a National Historic Register vote later this month.

Technically, it's known as a bascule truss bridge — "bascule" being French for "seesaw" or "balance" and referring to the bridge's counterweights, which help raise and lower it.
