It's sufficiently wide that it would normally be called an estuary rather than a river - and unless it's fed by a _lot_ of other rivers, the water will be moving so slowly that it'll need constant dredging as silt comes out of suspension. Navigable waterways tend to be a bit narrower than that. (The currently-maintained navigation channel on the Mississippi is 9 feet deep x 400 feet wide. Obviously parts of the river are wider than that, but that's enough for the actual traffic.) In the UK, we used horse-towed barges on the canal system (i.e. static water), but not on rivers; the water speed is usually too high for an animal tow to be effective. On a wide river you can use sails to get upstream; on a narrow one you're stuck with oars.
