I can’t find any mention of this fatality anywhere.
The location is US Highway 180 (a.k.a. Fort Valley Ranch Road)… between Flagstaff and the Grand Canyon.
ASDM
I found this while reconciling the 2014 data, this is adot incident=2879167
The data describes a classic motorist overtaking crash; both units were eastbound US180. Middle of the afternoon (so no lighting issues). The motorist was dinged for “speed too fast…”.
US180 is a two-lane rural highway with no shoulders. This location was within the Tonto National Forest. It’s, of course, not possible to tell the cyclist’s lane position from the database.
