This weekend, the Long Island Railroad and their contractor, 3TC achieved an important and amazing milestone. They pushed the 8 million pound New Hyde Park Road undergrade crossing and railroad bridge into place and reopened the mainline for railroad traffic. This was an amazing engineering feat; only the third time the technique has been used in the Americas (Covert Avenue was the first). The process involves pushing the tremendous structure across the ground, stopping every 20 inches to make sure it is going straight and not too high or not too low. If it’s too low, they simply add some dirt in front of it. If it’s too low, they dig dirt out of the way. The challenge is that they can only move it one direction. Luckily, they got it right.
