According to Google, live traffic is now free-flowing.

Photos posted to social media showed debris from the small house strewn across the lane under the Walter Strevens Drive overbridge.

“Prepare for EXTRA long queues,” one Facebook user wrote.

“Someone hit the under part of the Conifer Grove bridge and there is debris over 2 lanes,” they said.

Passer-by Emilie Mous described the extent of the crash site, saying there was “a huge amount of insulation, wood, small bits of glass, even some big panels that looked like a whole wall came off.

“It was easy to see from a distance and everyone was turning out of the slow lane, traffic turned very slow,” she said.
