This Mohave was the largest and most palatial of the paddle-wheelers on the Colorado River a century ago. The photo was taken in 1876, when the Mohave was docked at Yuma taking on school children for a May Day excursion.

The toll road — Central Ave. (then called Center Street) north of McDowell — was built by the Central Avenue Driving Association.

Buggies and wagons paid a 25 cent toll. Bicycles were free.
