HIGHWAY 25 / LA FONTAINE TUNNEL
The following closure is in effect until Monday at 5 a.m.:

SAINT-PIERRE INTERCHANGE
The following closure is in effect until Monday at 5 a.m.:
- The Highway 20 east ramp (Exit 63) to Route-138 west / Honoré-Mercier Bridge.
As a result the following are default closures:

- One of three lanes on Highway 20 between the 1st Ave. exit (62) and the interchange.
SAMUEL-DE CHAMPLAIN BRIDGE

TO BE EXPECTED
- On Highway 40, pavement work from April 29 to the fall between Morgan Blvd. and Lee Ave. (km 46) in Sainte-Anne-de-Bellevue and Baie d'Urfé will result in counterflow lane management during rush hours.
- In Montreal (Borough of Ville-Marie), two of three lanes on Robert-Bourassa Blvd. will be closed between Ottawa and William streets from Saturday at 7 a.m. to Sunday at 5 p.m.
- In Candiac, one of two lanes on Highway 15 will be closed in both directions at the Montcalm overpass (Exit 44) until Sunday at 8 p.m.
