I know few people use the Royal canal but it goes across a far larger part of our country, it should be protected and maintained.
After all it's entrance has only recently re-opened, and even then it's not easy to enter.
It should have been protected, just dumping gravel is insane.
When they first built that junction they went to the due care to put in a viaduct (or is it aqueduct?) for the canal, i'm sure it had to be closed then as well, but this is just reckless.
