It's no longer on their site, but I seem to recall FOTCP's alternative path design included a lower crossing of the Fitchburg Line on a prefab truss bridge, then crossed under the GLX next to the Fitchburg at ground level. Of course, by the time the project was re-bid, some of the supports for the higher crossing had already been built.
Of course, the grade is going to exacerbate the other problem with the path, which is that it's really narrow by modern design guidelines for the anticipated traffic loads.
That would be Gilman Square Station and the tracks will go on either side of it. Outbound roughly just inside where the temporary concrete barriers are and inbound between the island and the retaining wall. Here's a quick overview.Ok, this has been bugging me. Admittedly, I'm a neophyte regarding this project but what is that structure and isn't that smack-dab in the middle of where the new tracks are going?
Surprised they didn't finish the retaining wall while the crane can fit easily.Ok, this has been bugging me. Admittedly, I'm a neophyte regarding this project but what is that structure and isn't that smack-dab in the middle of where the new tracks are going?

Tiny little correction: they're doing this with the Medford St and School St bridges, on either side of the Gilman Square station. The Ball Square bridge was torn down and rebuilt from scratch, but it also has a pier between the inbound and outbound GLX tracks. I'm guessing they put it there because a central pier would be in the way of the outbound track as it shifts to the center approaching the station.At both Gilman and Ball Sq the inbound GLX is being routed behind an existing bridge abutment where the dirt has been mined out behind it, and a small span will bridge between the old abutment and the new retaining wall
They have, in fact, replaced (or augmented?) the timber retaining wall with a wall of pre-fab panels similar to those elsewhere on the raised grade of the the GLX/CR tracks between Titan Gas (Boston @ Harvard St) and Tufts' eastern reaches.It looks like there's juuuuust enough width to squeeze the inbound track through [ the "back way out" of the Titan Gas car wash b(https://goo.gl/maps/amDpjepRHMER2uR79)], but they'll probably want to rebuild that timber retaining wall.
It was a"budget add-on" that had to be added in the cheapest way possible, or not at all. At least they are doing itThey are really designing the bike path to give people a good cardio workout. Has the design team explained why it’s such a roller coaster?

TBH, while the Minuteman has lots of bikes moving at high speed, the Somerville community path with all it's winding has always been more tailored to pedestrians. While a "bike-highway" to downtown would be great, this isn't that. I'm picturing lots of walkers, bluebikes, Escooters and light-commuters catching the nearest train, like Somerville's existing demographics do. The ABILITY to give bikers a safer commute should make up for the slower safe-speed expectations.
