Zef shows us the aftermath of a head-on crash on the outbound side of Commonwealth Avenue near Allston Street (Allston's vortex of doom, of course), around 10:45 p.m.
Both outbound lanes blocked by police cruiser. One inbound lane taken up by fire trucks.
UPDATE: Zef reports that one outbound driver, impatient at the delays, tried to get around the scene by driving on the inbound side of Comm. Ave. - where he was promptly chased and stopped by police.
