I would say parking under the bridge is okay. Many do. Good traffic thru April. Yes, good launching area. Firm dirt bank meets rip rap under bridge. Easy smooth dirt to haul yak under bridge. Curvy trail is part of the Ancarrow park. It is historic with markers. “Slave Trail”. The Wall ( popular elbow to elbow fishing) is original rock port for commerce tradin, including humans for sale.

The dirt trail turns to paved walk/ Ike trail as it moves north, and inside the city flood wall. Rock hopping yields 1/8 -1/4 mile of shore fishing.
