Expect a redesign of the exits between College and Dalrymple in the near future.
That portion is unrelated to the segment of I-10 being improved under this Design-Build contract. The latter is from the Highland Road/Perkins Road interchange south of BTR (where the existing 6-lane segment ends) to the LA 73 interchange near Gonzales.
The segment of I-10 within BTR from LA 415 through the I-12 Split is still being developed and reviewed under an Environmental Assessment; it will still be a while before that segment is finalized and funded. That will probably involve redesigns of the interchanges along that section (Washington/Louisa/Dalrymple; College Drive, and Acadian Thruway).
An associated project to construct a left exit to Terrace Avenue near the I-10/I-110 Split for southbound I-110 traffic to avoid crossing through eastbound I-10 traffic to get to the Washington Street exit for the Mid City neighborhood, is funded and waiting for final design to be competed prior to construction.
There's also the final resolution for what will become of the Baton Rouge Toll Loop Bypass; whether it will follow the routes approved in the Tier I EIS (Airline Highway to Plank Road, then new alignment north of Denham Springs/Walker for the North section; new bridge around Addis/Gardere for a connection between I-10 for the South section).
Some would prefer the BUMP solution, which would freewayize Airine Highway (US 61/190) for its full length through BTR; and a Westbank Corridor paralleling LA 1 to Donaldsonville which would use the existing Jimmie Davis Sunshine Bridge to access I-10 south of Gonzales.
IOWs, it's still very much up in the air regarding Baton Rouge.
