In August 2009, a 9‐km twinned section of the TCH immediately east of Lake Louise (IIIB‐1) opened for traffic. Twinning work along the remaining untwinned 14‐km stretch of highway west of Castle Junction (IIIB‐2) has ended for the season. Work will continue into December 2009 on the installation of arches for two wildlife overpasses in this section. Highway construction will resume in the spring, with the majority of work expected to be completed by late fall 2010.

What’s Next?

1. The tendering process is underway for the final phase of the project from Lake Louise west to the Alberta/British Columbia border (IIIB-3). Reconstruction of the Icefields Parkway Interchange just west of Lake Louise will begin in November 2009, concentrating on blasting and installation of bridge foundations and piles. The new Interchange should open to traffic by late fall 2010.
2. Tree-clearing along the highway right-of-way further west of the Interchange will take place this winter. Highway construction will begin in spring 2010, with substantial completion slated for fall 2012.

Temporary delays during blasting can be expected.
Watch for workers and obey flag persons and posted speed limits .

Thanks for your patience! To date, over half of the 83-km section of the TCH in Banff National Park has been upgraded. These improvements will maximize motorist safety, reduce highway wildlife mortality and habitat fragmentation, and improve the flow of goods and services.
