If your going to close down Sherwood road, you would be better off routing traffic through Long St to the north. You would need to raise the bridge there which according to my napkin math would cost about $70 million.
Long St is seams to be better suited for through traffic movements especially for heavy vehicles. That bridge was also struck 13 times last year where as I can’t find a single incident of the bridge a Quarry Rd being hit recently.
This is a pointless metric. Who cares how long the gates are down? The thing that matters is how long someone has to wait on average.
As I said earlier, the Sherwood Road crossing is one with a lot of time with the gates down, but cars and pedestrians never have to wait for more than one crossing, so the delay is not that bad, and people in a rush have alternatives in any case.
I don’t think it is pointless otherwise why do they measure it? I agree that it is not the only factor that needs to be considered with assessing the impact of a level crossing closures. Other factors that need to be considered are traffic volume, crossing type, and whether there are other alternative routes. Longer closure times generally indicate a higher risk of accidents.
These are level crossings with longest reported closure times:
I have worked with government departments enough to know that they measure a lot of pointless things. I can say with confidence that it’s pointless because according to this Sherwood Road is the second worst on the network and I can state categorically as a local that it is just not that big a deal.
How much delay to trains or pedestrians or vehicles is caused?
EDIT: Wanted to add that part of the reason the delay is not that bad is that people avoid it because there are alternatives, so the traffic is not that great. Spending a lot of money on this one would be a waste in my opinion.
