Provincial Road 424 (PR 424) is a 34.5-kilometre-long (21.4 mi) north-south highway in both the Central Plains and Winnipeg Metro regions of Manitoba.

PR 424 begins in the Rural Municipality of Macdonald at a junction with PTH 2 (Red Coat Trail) between Starbuck and Oak Bluff, heading north as a paved two-lane highway to enter the Rural Municipality of Cartier and travel through Springstein, where the asphalt transitions to gravel.

Heading due north through farmland, it has an intersection with PR 427 (Wilkes Avenue) just west of Calrin while simultaneously crossing a railway.

Now paralleling the south bank of the Assiniboine River, the highway heads northwest through rural farmland for the next several kilometres, passing the Lakeside, Barickman, Maxwell, and Rosedale Hutterite colonies before coming to an end just south of St. Eustache at an intersection with PR 248.

[1][2][3] Prior to 2001, PR 424 was only 10.0-kilometre-long (6.2 mi), stretching from PTH 2 (Red Coat Trail) near Springstein to PR 241 (Roblin Boulevard / Lido Plage Road) just south of Lido Plage and just west of Beaudry Provincial Park.
