UPDATE (10:55 AM): State police are reopening the Mass Pike in both directions as I type. Should be completely opened by about 11:15. Heavy delays remain in place, so give yourself lots of extra time. Storrow Drive is going to be gridlocked, too, on the westbound side because of that lane closure at the Hatch Shell for the Children's Hospital Walk.
... at least downtown. Just passing it along that, if you were planning on taking the Pike through the Prudential Tunnel this morning, it's not going to happen.
State police have shut down the tunnel in both directions for a variety of reasons. Their Twitter account cites safety reasons - it's been pitch black in there since early this morning and the ventilation systems are down too. Plus, NStar crews likely have to access the area to get to the Scotia Street substation where this snafu started.
The Department of Transportation has reported that traffic eastbound is being detoured at Exit 18 (Allston Brighton tolls). Westbound traffic will be detoured coming out of the Ted Williams onto the Expressway southbound. Storrow Drive is going to be your best bet for an alternate but keep in mind that the right lane westbound will be closed through most of the morning into the afternoon by the Hatch Shell due to an event there.
So far there is no estimated time of reopening, but NStar has reported that the lights will hopefully be back on between 12-1 this afternoon. I'll let you know when it does.
