Hey, remember how the pedestrian bridge at 35th Street was supposed to open in April 2016, except they couldn't find an elevator for it? Yeah, me too.
Well, after a weirdly complicated series of events and some complaining, the city officially opened the bridge over the railroad tracks. (TLDR: They couldn't find an elevator that was made in America, and then they forgot to order air conditioners for the elevator.)
It should now be much quicker to get from, say, Tracks to The Source. There already is another pedestrian connection a few blocks up, near the 38th and Blake station, but this provides a couple more options.
