^Looking north from Warren Avenue in Detroit, April 2021.
Michigan Highway 1 follows Woodward Avenue, radiating north-northwesterly out of downtown Detroit to Pontiac. The southern end is at Adams Street in downtown Detroit. From there, Michigan Highway 1 follows Woodward Avenue, which serves as the division between east side address and west side addresses, up until Highland Park. (North of here, Detroit's streets align to a classic grid based on the cardinal directions, and a different street called John R Road serves as the dividing line.) Even as the predominant street grid becomes oriented along the cardinal directions beyond Highland Park, Michigan Highway 1 stays on its straight, north-northwesterly course. After passing through Royal Oak, Ferndale, Birmingham, and Bloomfield Hills, Michigan Highway 1 approaches Pontiac. Still on Woodward Avenue, Highway 1 ends at an east-west road called Square Lake Road. That Square Lake Road brings Business US24 in from the west, and it brings Business Loop I-75 in from the west; both of these business alignments take Woodward Avenue over from Michigan Highway 1, which ends at this junction.
My photo for Michigan Highway 1 comes from the median of Woodward Avenue in Ferndale. Just south of 9 Mile Road, the sign assembly in this photograph points northward for southbound travelers. The intersection of Woodward and 9 Mile features a classic Michigan left; the sign assembly shows the U-turn to the northbound side of Woodward Avenue. This photo was taken in April 2021 as part of the trip around Metro Detroit and the Thumb of Michigan.
