As several news outlets have reported, construction has begun on the new segment of the Lower Yahara River Trail. This trail will connect Madison to McFarland and, in a later stage, Stoughton. Once completed, the trail will provide a convenient, safe, and scenic link between those communities, likely attracting a lot of recreational as well as transportation cycling. Dane County Parks published two aerial videos of the location of the trail, one before construction started and one after. Definitely worth watching. Videos after the break.
