Hardly a week goes by that an over-height truck and a low-slung bridge on the Merritt Parkway have a close encounter of the worst kind: a collision. The King Street bridge in Greenwich has been hit 150 times in the last decade, 24 times last year alone. Despite $1.8 million in warning devices installed to prevent these strikes, they keep happening. All of the bridges on the Merritt Parkway, originally built to a minimum standard of eleven feet at the abutments, are too low for trucks. In some places the bridges are even lower due to roadbed re-grading. The road just wasn’t designed for anything but passenger cars. Trucks aren’t the only vehicles banned from the parkways. So too are RV’s, cars towing trailers, buses, hearses (in funeral processions) and all commercial vehicles.
