Nice trail, but dangerous crossings
I parked at the high school and picked up the trail at 11 Mile Rd. I took the trail all the way into Wixom and back. For the most part, it is a nice trail. Living on the other end of town, I found it amusing to see 12 Mile Rd. as a two-lane dirt road. (On my end of 12 Mile Rd., it ends at Lake St. Clair.) The trail does have a few rough spots in it, but I have been on far worse.
A few things to note. First, while heading north on the trail, the diversion of the path past Old Plank Road is not marked--it took me a moment to realize I needed to follow the paved path to the right, not the dirt path which continued straight ahead. And while the path is flat for the most part, there is a hilly section alongside the Lyon Oaks County Park. Past that, the trail goes past an industrial/office park, and not many drivers are willing to yield to bicyclists, as I found. (Going later in the day, they are more concerned with getting home rather than following safe driving practices.)
Also confusing is that at the intersection of this trail, and the connector that goes to the Kensington Metropark (right by the viaduct under I-96), there is no signage. If I hadn't known where I was going beforehand, I would probably have passed this connector by.
The crossings, though, can be very dangerous. I did not find the Grand River crossing to be much of a problem, but one other crossing (I believe it was Pontiac Trail) had a limited sight distance around the curve with a lot of traffic exceeding the speed limit. A few of the other crossings also had too much brush blocking views of the traffic (and also blocking the motorists' views of the path). At one crossing, there is a rut between the trail and the gravel road which makes it dangerous if approaching it at any kind of angle.
Overall I give the trail 3.5 star, but rounded up to 4 stars. The dangerous crossings detract from the overall experience, and a bad crossing (like I had, at Pontiac Trail) can ruin the whole ride. Since most drivers in southeast Michigan are extremely bike-hostile, some sort of traffic devices are needed in these areas.
I absolutely love this trail. I live in South Lyon, off 11mi and Milford Rd, so I have a variety of choices, for starting points, and directions, depending on what type of ride im desiring. I enjoy the variety of views, from covered canopy to the open areas past businesses and residences. I can ride to Wixom, Island Lake or Kensington. For safety reasons, I am pleased that they put the flashing lights at the Grandriver crossing (in New Hudson). If I need to run to Walmart, for something small. Biking is a good alternative. And that crossing use be a problem sometimes. But, most drivers dont know that they are suppose to stop when the lights are flashing. From and avid bike rider, I say thank you and keep up the good work!!
