The first bridge across the Canal in Lockport was located at the extreme eastern edge of the Big Bridge.  It was a narrow log bridge, only wide enough for one way traffic, with a log at eather side for guard rails.  The Canal was forty feet wide at the time.  Called the "Main Street Bridge" it was Lockport's only bridge spanning the Canal.

During 1843, when the first enlargement of the Canal was in progress, another wooden bridge, 105 feet wide, was built to carry Main Street traffic across the Canal.  Strangly enough,, this wooden "Big Bridge" or "Main Street Bridge" was built west of the direct line of Main Street.  By 1851, a portion of the Bridge was used as a marketplace.

The current "Big Bridge" is one of the largest bridges in the world.  The bridge represented a tremendous engineering achivement when it was completed in 1914.  The current "Big Bridge" is one of the widest bridges in the world.
