US 90 enters Crestview itself where the divider ends at CR 188, but remains four-lanes wide. Further into the city, it runs along the border of the Crestview Commercial Historic District and then encounters an intersection with Main Street where West James Lee Boulevard becomes East James Lee Boulevard, and then intrersects State Road 85 and Courthouse Terrace on the southwest corner of that intersection. US 90 leaves the historic district at Industrial Drive, and then passes by Twin Hills Park on the south side, and the Okaloosa County Jail on the north side. At the intersection with Del Cerro Camino, the road changes from a four-lane undivided highway to a four-lane divided one. East of Crestview, US 90 remains four lanes wide as it crosses a bridge over Mandle Creek, but narrows down to a two lane undivided highway before crossing the bridge over the Shoal River. The rest of the way through the county it includes both names "East James Lee Boulevard" and "Old Spanish Trail," as it meanders around rural Okaloosa County. As it enters Killingsworth Crossorads, the road runs along the north side of the P&A Subdivision, but the tracks begin to move away momentarily as it enters Deerland, where it encounters the southern terminus of CR 393. The tracks return to the side of the road just west of the intersection of Mare Creek Drive, and will remain on this side even as both pass through some last developments hidden away on both sides before it crosses the Okaloosa-Walton County Line.
