The Sidney Sherman Bridge is a strutted girder bridge in Houston, Texas. It spans the Houston Ship Channel (Buffalo Bayou) and carries the East Loop segment of Interstate 610 on the east side of the city.  It is more popularly known as the 610 Bridge or The Ship Channel Bridge.

History
Construction on the bridge was on the planning boards by the Texas Department of Transportation dating as far back as 1962.  Originally planned with a 400 foot (120 m) mainspan, it was rejected by the Army Corps of Engineers for fear that the narrow mainspan was a hazard to ships on the Ship Channel.  So a 600 foot (180 m) mainspan was in the plans instead, and the Army Corps approved of the design.
