The Grand Pont, designed by the cantonal engineer, Adrien Pichard (1790--1841), was built 1839-1844, while the Barre tunnel was pierced 1851-1855 and the bridge of Chauderon was built in 1905.
This reform was justified by the religious intolerance of the parlements; by their scandalous trials of Calas, Pierre Paid Sirven (1709-1777), the chevalier de la Barre and the comte de Lally; by the retrograde spirit that had made them suppress the Encyclopaedia in 1759 and condemn Emile in.
The Iroquois were assuming a threatening attitude towards the inhabitants, and Frontenac's successor, La Barre, was quite incapable of leading an army against such cunning foes.
At the end of a year La Barre was replaced by the marquis de Denonville, a man of ability and courage, who, though he showed some vigour in marching against the western Iroquois tribes, angered rather than intimidated them, and the massacre of Lachine (5th of August 1689) must be regarded as one of the unhappy results of his administration.
The intended victim was named Annie Gauthier, of Barre.
