When the Golden Gate Bridge turned 75 earlier this year, San Francisco's most famous landmark celebrated with fanfare only fit for San Francisco's most famous landmark.
Not to be outdone by its International Orange neighbor to the north, a certain other local bridge is marking its 75th birthday with its own unforgettable spectacle.

Starting next March, the Bay Bridge will be illuminated by 30,000 LED lights strung together to form a shimmering sculpture on the structure's north side.
Designed by renowned New York-based artist Leo Villareal, the "Bay Lights" will be the largest light sculpture ever created, spanning a whopping 1.8 miles wide and 500 feet high. (For those of you keeping track at home, that's seven times the size of the Eiffel Tower's 100th anniversary lighting.)
The $7 million project will be funded by private sources and is expected to generate more than $97 million for the local economy.
And fret not, nervous drivers: The entire bedazzled wonder will only be visible to those looking at the bridge from the outside.
The lights were tested for the first time this past week, and can be seen in the video below:
