I-93 shut at Southampton Street for 15 minutes as firefighters rushed to put out the fire in the ammo-filled camper on the northbound side.

Meanwhile, further north, part of the Leverett Connector is cracked. No cause for alarm, turnpike authority says, banning trucks weighing more than 40 tons just to be safe.

Cindy and Jeff give today's blazingly obvious traffic tip: Don't speed on the Leverett Connector/Tobin loop ramps, and you probably won't plunge 70 feet into either sand or gravel.

Car plunges to gravel site from ramp, killing man (although the absolute worst roadway in America for us acrophobes has to be the High Bridges into Charleston, SC - shudder!).

Disclosure: Back when I worked at a daily newspaper, I programmed our wire-service story-alert system to notify me whenever Associated Press moved a story about bus plunges - with which I would then compile the weekly newsroom bus-plunge tally-o-matic. I recently read some story bemoaning the end of bus-plunge stories, but I see that there are still plenty of bus plunges.

On the one hand, Tim admires the graffiti tagger who has gotten his giant "Syms" on locations that are obviously difficult to reach - such as the side of the I-93 upper deck.

On the other hand, Tim wishes the guy would knock it off already:

... There's a lot of graffiti out there that actually makes things look better. This doesn't. This is just about ego, and Syms should be ashamed rather than proud.
