Not yet outside of the Pensacola Metropolitan Area, US 90 enters Pace and gains the name Caroline Street. After the intersection of County Road 197A, the road turns northeast, where it crosses CR 197 (Chumukula Highway), and at County Road 197B (West Spencer Field Road) it turns east again. The road remains straight east and west as it encounters another segment of CR 197A. After the northern terminus with State Road 281 the road curves northeast, and officially enters Milton. It then crosses a pair of bridges over Pond Creek, where it passes by Mayo Park. Just east of the intersection with Glover Lane, Old US 90, a former segment of US 90 veers off to the right, but it is only a local street. The rest of the area is surrounded by portions of city territory, which becomes more widespread as it approaches the southern terminus of State Road 89 (Dogwood Drive), but also has a hidden concurrency with SR 89 east of there. A far more visible concurrency exists later on when the road curves back to the east where it meets the intersection with State Road 87, the eastern corners of which also includes the intersection of the Blackwater Heritage State Trail. From this point on the road narrows down to two lanes as it runs through the Milton Historic District, an area that has been on the National Register of Historic Places since November 12, 1987 and also includes an intersection with CR 191, which contains the east end of Old US 90. The district ends as the road crosses a bridge over the Blackwater River, and leaves the city limits.
