After completing a close proximity bridge inspection 187 kilometres out on the Finlay FSR, the employee was returning to Mackenzie for the evening. As the worker approached the bridge crossing, Tsedaka Creek at 32 km the driver side front tire blew. The driver tried to retain control of the vehicle however, due to the blown tire and the curve in the road, the vehicle collided with the guardrail, and the passenger side of the vehicle jumped the rail.

Once on the guardrail, the vehicle slid the entire length of the bridge and came to a stop at the concrete barrier on the opposite side of the bridge.

The driver did not sustain any injuries, and the vehicle had an estimated damage of $2,000.
