They finally finished their epic construction work on the 405, in between where I live and where I work. It had been going on since 2004.
I think it finished on Friday or over the weekend. This is the only news item I could find that mentions it, which surprises me because it seems like it would be kind of a big deal. Maybe Caltrans just hasn't put out a press release yet.
My commute is so, so much better now. Here's hoping it stays like this.
