Here's the best report on what happened.
Investigators said Williams, a bicyclist, was traveling westbound on Central Avenue just west of Winding Road towards Selby Boulevard when he was struck.
Police said the driver of a pickup truck, 53-year-old Coleman Lawson, of Harwood, was also traveling westbound Central Avenue when Williams got into the travel portion of the roadway towards the eastbound lanes of Central Avenue and was struck by Lawson's truck.
My initial thought was that the cyclist left a wide shoulder to move into the "travel portion of the roadway" (whatever that is), but if you look at the streetview, that is not much of a shoulder. Sounds like the driver didn't give enough space when passing.
