Autoroute 720 in Montreal is being downgraded to a western QC 136. That could happen upon completion of reconstruction of the Turcot interchange with A-15/20, and part of existing A-720, which could be in 2019 or 2020.
The A-720 route file could use some recentering and perhaps truncation (an official map, and GMSV, suggest A-720 ends short of Pont Jacques-Cartier). But I would defer most changes until A-720 becomes QC 136, after all the reconstruction is completed and QC 136 perhaps gets a new endpoint. In the meantime, I'll synch A-720's waypoint 5 with the west end of A-10, and correct A-720's east end label to RueNotDame.
There are no intersections with highways in the canqc route set, so it will be unaffected until the new QC 136 is added to the system.
