This weekend is shaping up to be a Montreal traffic nightmare with tons of road closures affecting key stretches of highway.

According to Mobilité Montreal, "major obstacles will be put in place during the weekend, particularly on Autoroute 25 north and south in the Louis-Hippolyte-La-Fontaine Tunnel, on Autoroute 40 westbound between the Laurentides and Décarie Interchanges and on route 136 east between the Turcot Interchange and the Ville-Marie Tunnel."

Work will take place at various times between Friday night and Monday morning. Some areas will be completely closed to traffic and will be detoured.

The following areas are to be avoided and you should definitely plan ahead if you're taking a drive:

• Autoroute 25 north will be closed to traffic "between Exit 90 [...] on A-20 west and the rue Notre-Dame Street E. / Curatteau entrance, including the Louis-Hippolyte-La-Fontaine Tunnel" from 12:30 a.m. Saturday to 5:00 a.m. Monday.
