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, SR 228 joins with the expressway to the east-southeast. They pass VyStar Veterans Memorial Arena, EverBank Field, and WJCT, before US 1 Alternate (US 1 Alt.; Martin Luther King Jr. Parkway) joins the concurrency. The two highways 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 Alt. 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).
