In 1968, the politicians here decided to save some money and built a causeway connecting Moncton and Riverview rather than building a bridge.

When I was a boy, my old man would take us down to watch the tidal bore when the moon was right in the spring of the year. It was "Neato man!" to watch the bore sweep up the river from bank to bank... over a mile wide in places and to here the rush of water.

Then, the twit politicians built the causeway. To save money, they destroyed so much.
The river silted up and was reduced to a fairly deep but narrow channel below the causeway, as shown in a picture in the link - the caption says "Note the wide flood plain." Okay, but that USED to river. A shallow lake formed upstream, but the only swimmers were gulls and such.

And then the twits conveniently built a dump (A TOXIC DUMP!) and baseball fields and so on upon the silt.

The river used to have schooners docked at the wharves - over a hundred at a time. The river used to yield fish and seals for the tables of thousands. It used to be a stop for thousands of migrating birds, again putting food on tables. It contained and fed aquatic life from it's headwaters to The Bay of Fundy. It was clean. Then it was filthy... even disgusting to look at by those who had never seen what I saw.

After many years of fighting, which even included support from the Kennedy family (yes, that family), the causeway gates were permanently opened a month ago.

The fish have returned. I actually have tears in my eyes. Maybe, before I die, I'll see the real tidal bore again.
