The next phase, 13 km at L'Ange-Guardien to route 317 will be studied next summer.
By 2032, the entire A50 should be widened.
Next phase to be widened is Lachute to Mirabel, 23 km in two phases. First phase, 6.6 km, is starting in mid-September. The next phase, 16.7 km, geotechnical studies are starting this summer.
