A reader writes in with this tidbit:
"I just wanted to let people know that there's currently a delivery truck wedged under the Red Line L tracks at Lawrence. The roof is peeled back sardine-can-style and it looks to be really stuck. It's in the westbound lane and causing quite a backup. Police are directing traffic, but it might make sense to avoid that stretch of Lawrence. The L is not affected."
Update: A reader sends in this pic of the "sardined" truck and adds:
"This happens about once every two months. Definitely the fault of the yahoo drivers who hit the warning bar and barge ahead, but still, the CTA needs to come up with something idiot-proof, as this can't be good for the bridge!"
