From my trip to Baton Rouge, last week, I can confirm the following...
LA 427(Pra) has been cut back from Siegen Ln (LA3246) all the way south to US 61 (Airline Hwy).
Interestingly enough, the fine folks in Ascension Parish have kept the signs for LA 427 between US 61 & La 73, a mere 1/3 of a mile length.
With the deletion of LA 427(Pra), that will leave a dangling end for LA 928 at Perkins Rd (former LA 427). I let the admins sort that out.
LA 1248 has no signs along Bluebonnet between La 42 (Burbank) and La 30 (Nicholson).
LA 3019 no longer exists along Veterans Blvd. in Orleans Parish. Saw no signs for that number while down there.
