What is that tiny bridge on the 210 near Marengo?

In 1972, after Pasadena residents complained about highway noise and visual pollution, parts of the 210 were built below grade—city streets were scooped out to create a sunken section of freeway. The once underground telephone and water lines were kept at their original level, however, and encased in a 94-inch-wide span of concrete that stretched over the freeway. The solution may not be pretty, but it was cheaper than digging up and relocating all those lines.
