The project included demolition of an existing bridge and construction of four new bridges for Highway 2. A substandard curve was removed and straightened, and a left entrance to Highway 2 for southbound traffic from Gaetz Avenue was reconstructed to crossover to the west side of the highway before joining the southbound lanes from the right side in a more conventional configuration. The existing bridges on this section of the highway had been constructed in 1962. The project was completed in 2018. Future Southern Alberta Highway 2 from Fort Macleod to south Edmonton is part of the CANAMEX Corridor, a divided highway with a combination of interchanges and several at-grade intersections except for a fully controlled-access freeway section in Calgary. The only set of traffic lights on this CANAMEX section are in central Claresholm; a bypass is proposed that would carry Highway 2 to the east of town on a new free-flowing alignment. A similar bypass to the east of Nanton is also proposed. A bypass of Fort Macleod has also been planned, tentatively designated as Highway 2X. It would be constructed in conjunction with a Highway 3 bypass of the town, making both routes free-flowing through the area. Plans have also been drafted for significant reconstruction of the interchange of Highway 2 and Highway 23 near High River. The existing cloverleaf interchange was built in 1967 and does not meet the current standards in Alberta's Highway Design Guide. In Calgary, where Highway 2 (Deerfoot Trail) experiences heavy congestion at peak hours, a major planning study is underway to determine the best course of action for upgrades to the freeway. In 2007, a study was completed by Alberta outlining plans for upgrades to the incomplete interchange of Glenmore Trail and Deerfoot Trail, one of the busiest road junctions in the province. Stage 1 of the proposed improvements would correct a pinch point on Deerfoot Trail by constructing a new three lane bridge to carry the northbound lanes over Glenmore. The southbound lanes would then be realigned on the existing bridges, such that Deerfoot Trail would be three lanes each way through the interchange, up from two. Central and northern Alberta Planning is underway to convert the Queen Elizabeth II Highway between Calgary and Edmonton to a freeway. Near Red Deer, traffic levels are close to 50,000 vehicles per day, and Alberta Transportation begins consideration of widening to six lanes when
