A worker is dead and a 300-ton crane is sitting on the bottom of the Wapiti River after a crash that shook the Grande Prairie region on Tuesday morning.
At 9:10 a.m. on June 16, the crane truck went through the railing of the Wapiti River Bridge on Highway 40 near Range Road 704, five kilometres south of Grande Prairie, and plunged approximately 50 feet into the water below. Police, fire, EMS, marine vessels, and search and rescue volunteers from multiple agencies arrived within minutes.
No witnesses saw the driver resurface. The crane has not moved from where it sank.
Alberta Occupational Health and Safety confirmed Wednesday the worker had been killed. The cause of the crash is under separate investigation by RCMP. The worker has not been publicly identified.
Why divers are not in the water
The Wapiti River is running high and fast following weeks of rainfall across the region. Divers assessed the conditions and made the call: the current is too strong to safely enter.
"The current is too strong," said Cpl. Mathew Howell, public information officer with K Division RCMP.
RCMP plan to deploy sonar technology next week to locate the crane and the worker precisely on the river bottom. That will guide decisions about how to recover both. There is no timeline for recovery. The crane remains submerged as of Wednesday.
What kind of vehicle this was
The crane involved has been described in reports as having a 300-ton lifting capacity. That figure refers to the maximum load the crane can lift, not the weight of the vehicle itself. The actual weight of the crane truck at the time of the crash has not been confirmed by RCMP or any primary source. Mobile crane trucks vary significantly in weight depending on the model and whether they are carrying counterweights or other loads at the time.
Why federal investigators are involved and not just provincial OHS
Alberta residents are familiar with provincial Occupational Health and Safety investigators responding to workplace fatalities they are the agency that laid charges in the LX Hausys marble slab case in Calgary and the Marigold Infrastructure case in Edmonton.
This case is different. Federal OHS jurisdiction applies when the work involved falls under federally regulated industries. Crane operation and heavy transport in certain contexts falls under federal jurisdiction rather than provincial. That means Labour Canada's federal OHS investigators are leading the workplace investigation rather than the Alberta government's OHS division.
The practical difference for the public: federal OHS investigations tend to take longer and their disclosure process differs from Alberta's. Charges, if any result, would be laid under the Canada Labour Code rather than Alberta's OHS Act.
What the bridge is and why this road matters to Grande Prairie
The Wapiti River Bridge on Highway 40 is one of the primary industrial corridors serving northwestern Alberta. It connects Grande Prairie to the oilfield, forestry, and agricultural operations to the south. Heavy equipment, crane trucks, tankers, logging trucks, and commercial vehicles cross it daily.
The bridge sits on the boundary between the County of Grande Prairie on the north bank and the Municipal District of Greenview on the south bank. That boundary meant multiple agencies responded Tuesday County fire, MD of Greenview Fire, and RCMP from both jurisdictions all on scene simultaneously.
The Highway 40 approach from the north descends a steep grade before reaching the bridge. That hill has been the site of serious incidents involving heavy vehicles before. The combination of a fully loaded crane, a steep descent, and a bridge is a scenario that experienced drivers in this region know to take seriously particularly when the river is running high and fast in wet conditions.
The bridge was just rebuilt
The Wapiti River Bridge and Highway 40 corridor recently completed a major upgrade. A $168 million project that began in 2021 widened the highway and built a new bridge to handle separate southbound and northbound traffic. That project was completed in December 2025 less than six months before Tuesday's crash.
The bridge is newer and wider than what it replaced. The railing that failed under the impact of a 300-ton crane is a specific engineering question that will be examined as part of the investigation. Alberta Transportation has not commented on the incident.
Highway 40 at the Wapiti Bridge has a history
Tuesday's crash is not the first fatal incident at or near this stretch of Highway 40. A motorcyclist died in a collision with a pickup truck at the Wapiti Bridge in a previous year. Multiple fatal crashes have occurred on Highway 40 south of Grande Prairie over the years the steep terrain, heavy industrial traffic, and weather conditions on this corridor make it one of the more demanding roads in the region.
The question of whether the steep grade approaching the bridge played any role in Tuesday's crash is one investigators will examine. No preliminary findings have been released.
What comes next
Sonar equipment will be deployed next week. Federal OHS investigators are active on the file. The highway has reopened. The RCMP investigation into what caused the crane to breach the railing is ongoing.
The worker who died has not been named. No company has been publicly identified as the employer. Both of those details will likely become public as the investigation progresses.
Anyone with information about what happened on the bridge Tuesday morning is asked to contact Grande Prairie RCMP at 780-830-5700.
