Autoroute 730 (A-730) is an autoroute located in the region of Montérégie, Quebec, Canada, and is freeway spur of Autoroute 30. Originally opened in 1992,[1] it was part of Autoroute 30 until November 19, 2010, when A-30 was realigned,[2] resulting in the bypassed section becoming a collector highway.[3] It extends from the A-30 / A-730 interchange to Route 132, just east of the Honoré Mercier Bridge, and is approximately 4.2km (02.6miles) long.[1]
From south to north; old exit numbers are former A-30 exit numbers.[4]
