the sort of thing you discover when working on a map.
I’m finally expanding the Greater Northshore and MEGAMAP the extra mile or so into Snohomish County as I’ve been promising. This expansion gets users to Edmonds and Lynnwood Town Centre – including the light rail station – so there’s some real meaning to it. In the east, it’ll eventually be important for the expansion of the Rail Trail, too.
Sometimes, tho’, when you’re doing stuff like this, you discover something. That happened tonight.
Check out this incomplete little map section-in-progress. There’s something to infer from it:
The crossings of Highway 99 at 208th and 228th have weight. Cyclists use them, even where the infrastructure stops short of the highway. They’re okay with both.
But they don’t use 220th. That’s fine – 220th interacts badly with I-5 not much further to the east, and has no infrastructure east of Highway 99 anyway. Of course they don’t use it.
212th, on the other hand, doesn’t have those problems. Infrastructure on both sides, even if a little short on the east. No I-5 issues.
And yet, people DO NOT WANT TO CROSS there. They REALLY don’t. They want to go half a mile or more out of their way north and cross at 208th, or a mile and a half out of their way south and use 228th instead.
It’s very specific to the crossing, too. They do use the infrastructure on 212th, on both sides. It lights up on the heatmaps, nice and bright.
But they don’t leave it. They don’t cross 99. Not there. They go north. Or maybe south, but mostly north.
And I can’t for the life of me tell you why. Not from looking at the maps I have. The intersections at 212th and 208th seem much the same to me, even from streetview. Infrastructure’s a little more complete at 208th, but not all that much – what’s half a city block between friends?
And yet.
People who bike there, they know something. Something I don’t, and something I can’t see on a map or from a satellite.
Neat, eh?
I wonder what they know.
