Do you support the planned I-10 and Perkins Road upgrades in Baton Rouge?

Louisiana's Department of Transportation and Development is redesigning the Acadian Thruway interchange on Interstate 10 in Baton Rouge, after acquiring and demolishing an adjacent hotel to clear land. Engineers have shifted the on- and off-ramps to the east side of Acadian Thruway.

Why it matters

The reconfiguration is designed to avoid closing the westbound ramp for more than a year, which would reduce commuter disruption during construction. Dual turning lanes are planned to ease heavy rush-hour backups for Baton Rouge drivers.

The plan adds dual turning lanes from Acadian Southbound onto I-10 East and an extra lane toward Perkins Road, while keeping the westbound ramp open for construction. The source does not give a construction schedule or cost.

The players

Louisiana Department of Transportation and Development (DOTD)

The state agency responsible for planning and building Louisiana's highways, including the I-10 interchange redesign in Baton Rouge.

The details

The state acquired and demolished an adjacent hotel to make room for the interchange redesign, then moved the Acadian Thruway on-ramp and off-ramp to the east side of the roadway. The new layout mirrors the I-10 West ramp setup at College Drive. Proposed Perkins Road upgrades include a roundabout, removal of a bottleneck traffic light, and an extension of Greenwood Drive behind local business hubs, along with new sidewalks, enhanced street lighting, and dedicated bike paths.

Roadmap

The Acadian Thruway redesign extends the mirrored ramp layout DOTD already used at College Drive to another Baton Rouge interchange. The approach keeps the westbound ramp open during construction, a pattern meant to limit closures on busy urban freeways.

Baton Rouge commuters will see changes to the Acadian Thruway ramps and Perkins Road, including a planned roundabout and new bike paths. Because the westbound ramp is expected to stay open, drivers may avoid the long closure that a full ramp shutdown would have caused.

The takeaway

Drivers and homeowners near Acadian Thruway and Perkins Road should watch for construction notices as DOTD finalizes its plans. The phased approach suggests the state is trying to keep traffic moving during the work.
