Super Bowl 50 is set to cause all kinds of transit blockages, but at least it's bringing a planned end to one Muni annoyance: the nighttime shutdown of underground light-rail trains, which has been ongoing since July 31st.
Muni says that work on the trains' new radio and phone systems is progressing on schedule, and the post-9:30pm shutdowns should conclude on January 22nd—the day before Super Bowl City begins construction.
