NewsFuture Construction on the Twelve Mile Lake Dam Has Obstacles SHARE ON: Kaitlin Livingston, contributor, Wednesday, Jan. 25th, 2017Construction on the Twelve Mile Lake Dam can’t start until some safety issues are fixed. Director of Ontario Waterways, Jewel Cunningham, says the bridge near the Minden Hills dam needs to be taken out, because holes in the deck and broken guardrails are dangerous, and it doesn’t meat the Canadian Highway Bridge Design Code standards. Cunningham notes it shouldn’t be too much of an issue, since the bridge is only used by pedestrians and a new walkway will be added once construction starts. The dam itself needs a bigger deck and the spillways shifted. No exact start date has been settled on yet.
