its junction with Highway 22X to its present terminus near De Winton. During planning, the segment had been temporarily designated as Highway 2X. Prior to the project, Deerfoot was effectively disconnected from the rest of Highway 2. Traffic continuing south to Fort Macleod proceeded west on a two lane bridge carrying Highway 22X over the Bow River, before turning south onto Macleod Trail, which was then designated as Highway 2. The section of Highway 22X over the river became Stoney Trail (Highway 201) in 2013, and a second bridge was completed in 2007 to carry the westbound lanes, while the original bridge built in 1974 carries the eastbound lanes. Interchanges were constructed at Barlow Trail, 130 Avenue SE, McKenzie Towne Boulevard, Cranston Avenue, and Dunbow Road between 2000 and 2004. The last set of traffic lights was removed in 2005 upon completion of the interchange at Douglasdale Boulevard, making the entire length of Deerfoot Trail a freeway. Since completion In an effort to reduce head-on collisions caused by vehicles crossing over the grass median in north Calgary, the installation of high tension cable barriers was completed in the first half of 2007. In 2009, modifications were made to the interchange of Peigan, Barlow, and Deerfoot Trails, built in 1979. The existing westbound to southbound ramp left little distance for traffic to merge, causing bottlenecks. The ramp was modified to first curve north and then loop back underneath itself, extending the merge distance before the three southbound lanes crossed Ogden Road and then the Bow River. In November 2009, construction of a major interchange at the northern terminus of Deerfoot Trail was completed, connecting it to the northeast and northwest sections of Stoney Trail. In August 2013, 96 Avenue NE was extended to the east across West Nose Creek and the Canadian Pacific Railway tracks to meet the existing interchange at Deerfoot Trail and Airport Trail. It provided an alternative to Beddington Trail and Country Hills Boulveard for access to the neighbourhood of Harvest Hills. The project included a controversial $470,000 piece of public art, a tall blue ring called "Travelling Light" that lies on the north side of 96 Avenue between the railway and Nose Creek. Highly visible from Deerfoot, the ring received national attention and was called "awful" and "terrible" by Calgary mayor Naheed Nenshi, and "an example of bureaucracy run amok" by Councillor Jyoti Gondek.
