"The highway rolls over the Oak Ridges Moraine " sounds awkward. "The highway" is overused in the route description. The sentence "The terrain continues to become rougher progressing northward, with the highway diving into valleys and along cliffs overlooking the many lakes dotting the region, following the former Bobcaygeon Colonization Road for many parts" needs to be completely reworded.
The lead should include some historical information. In addition, the history only focuses on the route before it was created. Is there any more recent history that can be added?
Alright I've made some changes, see if this is any better. There is a LOT more to the history, but I simply cannot find any source (besides the unreliable Cameron Bevers source) detailing the realignments and bypasses constructed in the forties and fifties in the north. I've dug up what I can to fill the 70-year gap. Cheers, ʄɭoʏɗiaɲτ¢06:18, 20 May 2010 (UTC)reply
