Since a covered bridge in Long Grove reopened last August, truck drivers have hit the top of the bridge – with a clearance of 8’6″ – 17 times.
“We have made so many attempts to make the signs more visible, and it just keeps happening.” said Trustee Jennifer Michaud. “I live very close to the downtown, and I always know when the bridge is hit, because I see the helicopters come in. And I’m just, ‘Oh, another one.'”…
“People look at their phones and their phone tells them to go this way, and Google doesn’t know that they are driving a truck,” she said…
One option is an overhead detection system that would sense when a truck of a certain height approached the bridge and send a warning signal to the driver. Such a system would have recurring costs, including maintenance.
Another option could be to prohibit truck traffic.
This seems like a clash of transportation eras. The covered bridge is from an older era and this is part of its current appeal. The bridge invokes tradition and likely brings in curious visitors. The bridge is part of the local character. Here is how the Historic Downtown Long Grove puts it:
As one of the last iron trusses in The Chicago area, the single-lane Covered Bridge is so iconic, it’s quite literally become Long Grove’s emblem. For over 100 years, the bridge has stood as the symbol of this crossroads town, one of the first in the country to pass a Historic Landmark Ordinance (in 1962) so that new construction need conform to its unique and charming style. The Covered Bridge has transcended its historical role as a functional necessity and a tourist attraction into something of far greater significance – the Queen and Protector of this special place we call Long Grove just 35 miles NW of Chicago.
As the gateway to the historic downtown, the Covered Bridge is where Long Grove’s quaintness begins and ends. Not only does the single-lane bridge buffer the town from being a major thoroughfare to Route 53, but there’s also something enchanting about waiting at a stop sign while the car opposite of you slowly passes over the bridge before your turn.
To paraphrase one resident: “I love how you need to stop, which suggests for you to relax, and prepare to step back in time to a less hectic world. As you ease across the bridge, the sound and feel of the bricks and timbers under you add another reminder that you’re entering a special place.”
At the same time, today’s vehicles are bigger and technology steers drivers down particular roads to get them from Point A to Point B. No community today would choose to build such a small bridge today. Can everyone get what they want in such a situation?
This reminds me of driving through tunnels on the Pennsylvania Turnpike where they are clear signs prohibiting trucks carrying certain materials. Presumably, there is some sort of enforcement system. An overhead sensor could work. So could posting someone on each side of the bridge who can watch traffic and stop vehicles that are too tall.
This is not just a problem for this covered bridge. This can happen at drive-thrus, gas stations, parking garages, and other places with limited heights. If someone asked me how tall my vehicle is, I could guess but I would not know for sure. And if I was driving a different vehicle than normal, like a moving truck or a tall pickup, I might not even think about it.
