A large part of the Peter Lougheed Provincial Park west of Calgary has reopened after last month's flooding caused major damage.

The state of emergency for the area, which was closed June 20 when floodwaters ripped through the park, has been lifted.

Richard Starke, minister of Tourism, Parks and Recreation, said Kananaskis Country was seriously impacted by the flooding.

A map, which is posted below, gives a complete picture of what is open and closed in the area.

Highway 40 into the park has also reopened to the Kananaskis lakes turnoff, and the province has rebuilt the Evan Thomas bridge.

"As an innovative solution, a temporary prefabricated bridge was installed to allow one-lane access over the Evan Thomas bridge," said the province in a release.

Campgrounds now open, refunds available

Road reconstruction has been continuous in the area after raging floodwaters forced the closure of the Trans-Canada Highway nearby.

All front-country campgrounds are open, but some trails and facilities still under construction remain closed.

Alberta Parks is offering full refunds for campground reservations that have been cancelled. To receive a refund, call 1-877-537-2757.

Park visitors are being warned that some trails may have been altered and they should exercise caution while hiking.

Visitors are advised to check the government's website for up-to-date information on park services and facilities.

Volunteers can also sign up on the website to help clean up areas of the park still damaged by flooding.
