No one was seriously hurt on Monday morning in a head-on crash involving two commercial dump trucks hauling sand and a Ford pickup on Vermont Route 100 in Waterbury Center, according to state investigators.
The incident, however, closed the two-lane highway for more than five hours, forcing traffic to detour on back roads in Waterbury and Stowe.
The crash occurred shortly after 9 a.m. in a stretch of Rt. 100 near the Waterbury-Stowe town line south of the northern intersection with Gregg Hill Road.
Because the incident involved commercial vehicles, inspectors from the Vermont Department of Motor Vehicles are handling the crash investigation. Vermont State Police responded to the incident and assisted, along with the Waterbury Fire Department, Stowe Police and Waterbury Ambulance Service.
According to a report from DMV Inspector Clay Knight, the investigation so far has determined that the incident began as two dump trucks loaded with sand were traveling southbound on Rt. 100. Both were headed from a sandpit in Johnson to a job site in Berlin, Knight said.
For a reason yet to be determined, a 2018 Ford F-150 pickup headed north on Rt. 100 crossed the center line into the opposite lane and into the path of the two larger trucks.
The pickup collided with the first dump truck, a 1996 Western Star 4900, which went off the east side of the road and tipped over, Knight said. The pickup also struck the second dump truck, a 1999 International F-9370 model.
The driver of the pickup was Arevalo Rodriguez, 37, of Chelsea, Massachusetts, according to the crash report. Sidney Sumner, 62, from Bristol, was driving the first dump truck that tipped. Both Rodriguez and Sumner suffered non-life-threatening injuries, according to the report. They were transported to Copley Hospital and Central Vermont Medical Center, officials said. Both of their vehicles – the pickup and the first dump truck to be hit – sustained heavy damage and were totaled, according to the report.
The driver of the second dump truck, 59-year-old William Jackson of Leicester, was unhurt. Officials said his dump truck had disabling damage.
Knight noted that all three drivers were wearing seatbelts at the time of the crash.
Rodriguez’ pickup was registered to Leom Remodeling from Massachusetts, Knight said. The two dump trucks are owned by Sid Sumner Inc., located in Bristol.
As a result of the crash, Rt. 100 was closed into the afternoon as responders and investigators assessed and cleared the scene. Knight said assistance came from a number of entities, including Agency of Transportation personnel who brought temporary signs for the road closure and inspected the roadway for damage. Staff from the nearby Walker Construction firm brought heavy equipment to the effort, including a bucket loader and excavator. Anytime Towing and Charlebois Towing companies assisted with removing the disabled vehicles, the report noted.
Knight said some spilled sand from the tipped truck still needed to be cleaned up. There also was some oil leakage, which was evaluated by a state hazardous materials crew, Knight said. Officials at the Agency of Natural Resources were alerted and were arranging for cleanup of the spilled oil, he said.
Rt. 100 was reopened for normal traffic shortly after 2:30 p.m.
DMV officials say that the cause of the crash is still under investigation. Anyone with information that might assist investigators in this case may contact Inspector Clay Knight at Clay.Knight@vermont.gov.
