Eastern route Louisiana A state alternate route begins in Gretna and crosses the Crescent City Connection (US 90 Business) into New Orleans. Tchoupitoulas Street leads along the river to Audubon Park, with Magazine Street, Leake Avenue, and Oak Street continuing from the other side of the park to the city line. In Jefferson Parish, the road becomes River Road (partly LA 611-1), from which the Great River Road jogs northwest on Hickory Street to LA 48. LA 48 hugs the river to Norco, where US 61 crosses the Bonnet Carre Spillway to LA 628, connecting in LaPlace to LA 636-3 and LA 44. Another river-hugging highway, LA 44 leads to Burnside, where LA 942 continues to Darrow; the route then follows LA 75, LA 991, and LA 327 around the curves of the river to Baton Rouge. Through that city, the Great River Road uses LA 30, Government Street, River Road (partly US 61 Business), State Capitol Drive, Third Street, Spanish Town Road, Fifth Street, and Capitol Access Road (LA 3045) to I-110. At the Airline Highway interchange on I-110, the National Route comes over the Huey P. Long Bridge (US 190) and turns north to follow I-110 and US 61 into Mississippi.
