The summer solstice and St. Jean Baptiste will be celebrated on Quebec's roadways in the traditional fashion with slow-moving processions of overheating cars and plenty of honking.

Transport Quebec has planned extensive highway closures in and around Montreal as the inbound lanes of the new Champlain Bridge are connected to the highway network.

However work will be done on many other highways in the region and we can expect lots of roadwork on the July 1 long weekend too.
