I agree with George...
If you go to the mouth of the river near the harbor, you can get a wheelchair on the Riverwalk from there.
Thank you for the immediate response @Tejas, @Avinash, @KimberlyAnn
The access we used had stairs. But the newer parts are accessible.
I am also a tourist here and did not see any wheelchair along riverside.
There are ramps along the Riverwalk. I'm not sure if they provide wheelchairs there.
