Emergency responders in the Northland were busy Friday morning.

Two construction workers were apparently struck by lightning working on a bridge near the interchange of 169 and 152 highways.    They were taken to the hospital shortly after 7am.

The pop-up thunderstorm generated a lot of cloud-to-ground lightning, which also reportedly hit a house in the 7200 block N Strathbury.

In traffic, there was a four-car pileup on four-car pileup near US-169 on Missouri Route 9.  Police shut down highway 9 while they investigated the accident.
