Florida State Road 228

Western segment

SR 228 begins at an intersection with U.S. Route 90 (US 90, Macclenny Avenue) in downtown Macclenny. At this intersection, the roadway continues as County Road 228 (North 5th Street). It heads south-southeast through town, passing Macclenny City Hall and the Emily Taber Public Library. Around the intersection with Jonathan Street, the road curves to the southeast. It crosses over Turkey Creek before leaving town. Approximately 3,000 feet (910 m) after leaving Macclenny, it meets its eastern terminus, an interchange with Interstate 10 (I-10). At this interchange, the roadway continues to the southeast as another instance of County Road 228, this time known as Maxville–Macclenny Road.

Western terminus to Downtown

The route resumes at an intersection with US 301 in the southwestern corner of Jacksonville. At this intersection, the roadway continues as County Road 228 (Maxville–Macclenny Road). US 301/SR 228 run concurrent to the south-southwest for about 1,000 feet (300 m), until SR 228 departs to the northeast on Normandy Boulevard. A short distance later, it meets the northern terminus of County Road 217. Then, it travels through Cecil Center, passing the Cecil campus of Florida State College. The highway passes by Herlong Recreational Airport, before meeting an interchange with I-295 (Jacksonville Western Beltway). SR 228 passes Gravely Hill Cemetery and John D. Liverman Park. While passing the park, the highway crosses over Cedar River. Then, it intersects SR 103 (Lane Avenue South). After that, it begins to curve to the east. At the intersection with Cassat Avenue, it takes on the Post Street name. At Hamilton Street, it heads northeast and curves back to the east past Edgewood Avenue. Then, it intersects SR 129 (McDuff Avenue). The two routes head concurrent to the south for about four blocks, to an intersection with US 17 (Roosevelt Boulevard). At this intersection, SR 129 meets its southern terminus, and SR 228 heads concurrent with US 17 to the northeast. Less than 1 mile (1.6 km) later, the two routes have an interchange with I-10. The three routes head concurrent to the east. At an interchange with I-95, I-10 meets its eastern terminus, while I-95/US 17/SR 228 head to the northeast, crossing over McCoy Creek. At an interchange with Union Street, US 17/SR 228 split off to the east, concurrent with US 23. The three highways enter downtown.

Downtown to eastern terminus

At Main Street, they intersect US 1. Here, US 23 meets its southern terminus and SR 228 turns onto US 1 south, while US 17 turns onto US 1 north. One block later, US 90 (West Beaver Street) joins the concurrency. Four blocks farther to the south-southwest, SR 228 splits off onto West Monroe Avenue. One block to the east, at Ocean Street, it intersects the northbound lanes of US 1/US 90/SR 228. A short distance to the east-southeast, SR 228 meets the western terminus of the Hart Bridge Expressway, a freeway that connects downtown to the Southside neighborhood. Here, it joins with the expressway to the east-southeast. They pass Jacksonville Veterans Memorial Arena, EverBank Field, and WJCT, before US 1 Alternate joins the concurrency. The two routes cross over the St. Johns River on the Hart Bridge. Shortly after the bridge is an interchange with SR 10 (Atlantic Boulevard). Almost immediately, US 1 Alternate splits off onto Emerson Expressway. Then, SR 228 crosses over Little Pottsburg Creek. After that, it has an intersection with SR 109 (University Boulevard). The road continues to the east-southeast and curves to the southeast to meet its eastern terminus, an interchange with US 90 (Beach Boulevard).
