Understanding Baton Rouge's geography
Why Baton Rouge's drive times defy radius math.
The Mississippi River cuts off any westward expansion of a 15-minute isochrone, while the I-10 elevated corridor through downtown creates bottlenecks that compress northward reach toward Scotlandville. I-12 eastbound toward Denham Springs opens up rapidly in off-peak hours, making that corridor deceptively large on a time-based map.
Franchise developers should focus on the Perkins Road corridor and the Siegen Lane/I-10 interchange, where suburban retail density is highest and traffic flows are more predictable. The Bluebonnet Boulevard spine through the southern suburbs connects Summa Hospital, LSU, and major retail — a reliable daytime traffic generator.
