Curving back to the southeast, the road finds its eastern terminus at US 90/SR 10 in Milligan, just southwest of Crestview.

[3] The Florida Department of Transportation annual average daily traffic (AADT) numbers for 2012 show an average of 4,300 vehicles on the Escambia County portion of the road and into Santa Rosa County to Jay, decreasing sharply to 2,600 and then 1,300 vehicles as the road approached its intersection with SR 87.

It appears that the portion of today's SR 4 from Munson (starting at mile 25.932) to its eastern terminus corresponds to this 1922 auto trail.

[8] In Okaloosa County, SR 62 runs into Baker as third-class road, but the final stretch from Barker To Milligan had already been improved to a second-class surface.

Only about half of this extension was bituminous, to just north of what became I-10, while the southeastern portion of the road was graded and drained, but not surfaced.

It spans from a secret overlap with US 90/SR 4 east of Milligan southeast toward State Road 85 in southern Crestview, Florida.
