Longest Covered Bridge
New Brunswick has its fair share of superlatives, but this Hartland attraction may be the most surprising. In what is otherwise a rather sleepy little town, the St. John River is spanned by the longest covered bridge in the world—1,282 feet long. A national and provincial historic site, the bridge opened in 1901 and is still used by traffic crossing the river between Routes 103 and 105---maximum vehicle height is 13 feet 9 inches; maximum weight 10 tons. Through the openings in the side walls, passengers can enjoy nice river views in both directions. There also is a safely separated walkway that you can walk across. A fun fact is that of the total 131 covered bridges in Canada, New Brunswick has 58.
There's only room for traffic going one way at a time across the bridge, and there are no traffic lights; so stop and check whether there's anything coming the other way and wait your turn if necessary, then turn on your headlights before driving across.
