In 2002, the two largest newly twinned segments of Highway 43 had opened to traffic. The largest segment stretched from Whitecourt to west of Two Creeks. The other segment stretched from west of Highway 733 to Crooked Creek, which included a realignment to bypass Bezanson. The interchange with Highway 2 north of Grande Prairie also opened to traffic on October 3, 2002. By 2003, the first newly twinned segment in over 20 years at Highway 43's southeastern end was open to traffic – starting from west of Gunn and ending east of Highway 765 near Glenevis. Also, the brief 2 km segment from Highway 2 (north of Grande Prairie) to east of Highway 2 opened upon completion of an interchange at Highway 2 and a grade separation over a CN rail line. By 2004, three additional segments of Highway 43 had been twinned. The first was from northwest of Fox Creek to near Giroux Lake. The second was filling in the gap between Fox Creek and Whitecourt from west of Highway 947 to west of Two Creeks. The third was from east of Highway 658 to east of Green Court/Highway 18.
