Gosh, I'd just assumed the crossties would be set in stone ballast, but then again I was (wrongly) picturing the concrete viaducts in new systems like LA and Norfolk VAThe sunlight passing through the elevated superstructure is great. I hope the design allows for some of it after the ties and tracks go in,

Sure, and the Lechmere Viaduct still does (though it is hard to experience from most angles most of the time). Do we actually know they're setting the crossties across the steel beams here?Old Orange Line El had plenty of daylight in spots between the tracks, as it was wood crossties on open deck.

Reminds me distinctly of the Southwest Corridor which Orange Line problems aside is certainly the highest quality bit of Commuter Rail tracl infrastructure in the networkAm I the only one who loves transit trenches with defined walls and structure like the ol corridor much more than just dirt and bushes and crap? I like the exactness of it, the cleanliness, the uniformity, the separateness... I dont even know why but Im excited to see how quality and prepared this corridor soon looks vs the unkemptness of before.
I wonder why those beams are painted green and the ones further towards Brickbottom aren't. Is it just that it's a high-visibility location so they wanted them to be prettier?
No...probably just more sensitive work windows when they're painting above roads and sidewalk. That's night work in Lechmere Sq. They can do it 24/7 everywhere else, and use a lull in other schedules to backfill paint chores if they need an excuse on a given day to keep someone busy.
Pretty sure the beams were painted long before they arrived on the property. Haven't seen paint equipment anywhere near the site, and I was riding through semi-regularly before the lockdown.No...probably just more sensitive work windows when they're painting above roads and sidewalk.

There is probably an earth reinforced wall built behind the thin facia wall. Horizontal layers of geofabric separated by select material go a ways back into the soil behind the facia wall. I've deigned similar structures myself. They're very commonly used.Ball square bridge and near school street bridge.
I’m surprised how that thin wall can hold all that weight for the berm
The green beams arrived already painted. They had them sitting at the site weeks before being hoisted onto the concrete supports.Pretty sure the beams were painted long before they arrived on the property.
