Most People Have No Idea This Unique Tunnel In San Francisco Exists

It's impossible to get bored in San Francisco, even if you feel like you've done and seen everything. In fact, narrowing this idea down to even Golden Gate Park is difficult with its myriad nooks, crannies, winding trails, wide open green spaces, and even this small but unique and historical bridge and tunnel located on the east side.

As you enter Golden Gate Park from the end of Haight Street, you will find a small man-made lake. This is Alvord Lake, which dates back to the 1880s, and is named after park commission president William Alvord.

This is how it looked back in 1904. Following the lakeside path leads you to the Alvord Bridge.

Constructed in 1889 by Ernest Leslie Ransome, Alvord Bridge is the first structure of its kind built with iron-reinforced concrete.

The bridge is one of the few structures in San Francisco that survived the 1906 earthquake unscathed. It's only 64-feet wide and 20 feet in span, and is considered a National Historic Civil Engineering Landmark.

Today, cars pass over the bridge on Kezar Drive, while pedestrians can walk underneath it, from the east edge of the park into Sharon Meadow.

And pedestrians get quite an experience in the tunnel, which feels like a wild cavern with its artificial stalactites.

But the bridge and tunnel itself may be more picturesque from afar...
