There's a new construction site affecting commuters in Pointe Claire.

The ramp from Highway 20 East to Sources Blvd. North is now down to one lane.

Meanwhile the ramp from Sources Blvd. South to Highway 20 West has new weight restrictions: 18 tonnes for a truck, 30 tonnes for a tractor trailer, and 40 tonnes for a highway train (a truck pulling two trailers).

Transport Quebec says these measures will be in place for the "medium term" while it works on the interchange.

The Ministry expects these measures will be in place until the end of 2016.
