Bus line explosion at Burnaby-Vancouver border causes traffic snarl

Parts of the intersection of Kingsway and Boundary Road, on the border of Vancouver and Burnaby, have been closed againafter trolleybus lines caught fire and fell onto the road early Friday morning.

It's not clear what started the fire on the lines, but they were arcing around 1 a.m. PT underneath a bridge connecting the north side of Kingsway to Burnaby's Central Park.

The lines then exploded, before fallingacross westbound Boundary Road.

No one was injured or trapped, but first responders had to shut down the normally busy intersection. The road briefly reopened early Friday but has since been shut down again. Boundary is closed from Imperial Street to Vanness Avenue.

Sections of Kingsway are closed between Patterson Avenue and Boundary Road as crews deal with thewires.
