Upcoming road closures and restrictions on Mountain Highway at Thames Creek

We are working on Mountain Highway at Thames Creek (north of Borthwick Road) to increase capacity of the existing culvert.

Construction is expected to be completed in January 2018, but will be delayed in snowy or slippery road conditions.

This work will require some road closures on Mountain Highway, north of Borthwick Road, and restricted access to the Mt. Fromme parking lot. Pedestrian, bicycle, and emergency vehicle access will be maintained throughout construction.
