The Mount Vernon Trail and a few roads nearby are under renovation this summer. This detour, located south of the long Dyke Marsh bridge, bypasses two short bridges that are being replaced. A second detour is about 200 yards north of this one. Further south, Northdown Road is being rebuilt, as are East and West Boulevard Drives south of the stone bridge on Alexandria Avenue. I haven’t had difficulty getting through all this on my bike.
One life, some bicycles. A million possibilities, zero clue!

Thanks for posting. It’s kind of a hassle now, but I’m glad they’re replacing those short bridges. I wiped out on one of them last year. Also glad they’re repaving all the way up to Collingwood.
