Cosign on this one.
Louisiana is kinda weird regarding signing interchanges through cities.
On I-10, when they added the Louisiana Avenue interchange in Lafayette, they also revised the I-49/US 167 BGS's for the exits for 167 South (Future I-49 South) to read "Morgan City" rather than "Lafayette". You'd think they would have used "Downtown Lafayette" and left "Morgan City" for a secondary reassurance sign.
However...on I-49 through Opelousas, they have the "Opelousas NEXT 3 INTERCHANGES" signs up, but they still have the US 190 West BGS labeled as "Opelousas" rather than "Downtown".
Some consistency would be nice, LADOTD.
