Suicide Junctions
"Suicide junctions," I calls 'em. The ones with which I'm most familiar are on I-278, just north of the Verrazano Narrows Bridge in Brooklyn, New York, and along North Mopac in Austin, Texas, but they must exist all over the US. Traffic about to enter the freeway must first cross the line of faster-traveling offcoming cars, the intersection's on- and off-ramps crossing in a shallow <B>X</B>.
