Tall trucks, GPS endanger historic covered bridges
LYNDON, Vt. — One of Vermont’s historic covered bridges has fallen under threat from modern technology.
Box truck drivers relying on GPS continually crash through Lyndon’s 140-year-old Miller’s Run bridge despite signs, including a flashing one, to deter vehicles that are too tall or too heavy from crossing. Drivers can face a fine of $5,000 from the town, plus state penalties.
Still, the bridge keeps getting whacked.
“GPS is the most general excuse that is given by drivers that do hit the bridge,” said Justin Smith, Lyndon’s municipal administrator. He said the real problem is lack of common sense.
The bridge, built in 1878 and renovated in 1995, lies on a shortcut motorists use to avoid downtown Lyndonville. The community, which has five historic covered bridges, including two in use, calls itself the “Covered Bridge Capital of the NEK,” short for Northeast Kingdom area.
Police Chief Jack Harris estimated the Miller’s Run bridge has been struck two dozen times, and at least once, two times in one day. The drivers are using GPS programs for cars rather than commercial vehicles, he said. Typically the damage is cosmetic, though on two occasions the bridge had to be closed for several months for repairs, he said.
In 2019, a delivery truck hit the supports and the engineering and repair costs were nearly $100,000, said Smith. About half the time, the town recoups insurance money from the drivers — if it catches them. Many just drive away.
“They will claim that they didn’t know they hit it and yet you’ll see the truck stop in the middle of the bridge and they’ll look up to see that they’re hitting the bridge,” Harris said. “I can count the number that have stopped and waited on one hand,” Harris said.
Many are inexperienced in driving box trucks, such as people who may have just rented one to move, he said.
“Every now and then we’ll get a large camper being pulled through and those generally get damaged because the bridge will take air conditioning units right off the top,” he said.
A neighbor’s security camera trained on the bridge has helped track down some errant drivers.
Lyndon is far from alone, according to Bill Caswell, president of the National Society for the Preservation of Covered Bridges.
“You can visit many covered bridges throughout Vermont and other states and see broken boards on the portals and broken or missing roof braces,” he said by email.
Last November, a tractor trailer truck seriously damaged a covered bridge in Princeton, Illinois, and a bridge in Ohio was damaged in a similar way a year earlier, he said. A historic covered bridge in Cobb County, Georgia, was struck numerous times until metal barriers were installed at each end, he said. It also has a warning signs and flashing lights.
“Even with all the warnings, the barriers are still struck,” Caswell wrote. “But the bridge is now protected.”
A box truck rental company in Lyndonville now warns drivers about covered bridges in the area, and the town is considering installing a steel beam in front of the bridge to force trucks that are too tall to a full stop.
A Google spokesperson said “Google Maps is designed for drivers of standard-sized vehicles. To get the best routes, we encourage drivers of trucks and larger vehicles to use navigation tools designed specifically for those vehicle types.”
