General Douglas MacArthur Tunnel

This is the tunnel that people reach before going to the Marina or Golden Gate Bridge. I once drove this pass this tunnel daily to see my girlfriend. And almost every time I would see the police catching someone right before California St. or an accident right before Crossover.

I drive through this tunnel every morning and, because I love Unilocal,I actually looked to see if it was listed.
Lo and behold it wasn’t! Time to give it it’s due.
The General Douglas MacArthur Tunnel (a.k.a. The MacArthur Tunnel or the Presidio Tunnel) is a highway 1 tunnel located on the grounds of The Presidio
It carries California State Route 1 under a large hill at the Presidio Golf Course, and connects Park Presidio Boulevard to US 101 on the Golden Gate Bridge Freeway (better known as Doyle Drive).
Please do not honk while driving in the tunnel as it can be VERY loud.
