Wednesday's Google doodle celebrates the anniversary of a Canadian landmark.

The longest covered bridge in the world opened July 4, 1901, in Hartland, the self-described smallest town in New Brunswick.

It's a wishing bridge, a kissing bridge and a national historic site.

Original toll charges were three cents for a pedestrian and six cents for a single horse and wagon to go across the 390-metre bridge built by the private Hartland Bridge Co.

The bridge was projected to cost between $70,000 and $80,000, but came in at just $27,945 because local labour was used and the structure was built out of wood instead of steel, according to the town's website.

The province bought the bridge in 1906 and removed the tolls.

They say that if you make a wish, then cross the entire length of the bridge with eyes closed, fingers crossed and breath held, your wish is likely to come true.

And, as legend has it, the enclosed bridge was the perfect cover for lovers in a more modest era to sneak a kiss. Modern couples carry on the tradition.
