Chinook Roads Partnership has entered a project agreement to design, build, finance, maintain, and rehabilitate the Southeast Stoney Trail (SEST), as well as operate and maintain certain segments of the existing highway in Calgary, Alta., which Alberta Transportation has or will construct.

(SNCC) and Acciona Infrastructures Canada Inc. (AIC); Acciona S.A. (Acciona) and highly rated SNC-Lavalin Group Inc. (SNC; BBB+/Stable/--)
