old tunnel in the hills

in the 1860s back when there were still horse drawn carriages the way around the berkeley hills took about 3 hours to get to Orinda. if you went around it all the way up to Martinez may take you half a day. there for in the 1870s the oakland and contra costa tunnel company built the kennedy toll road and dug out 100 feet of dirt was dug out of the contra costa side and 200 feet were dug out of the oakland side until the company ran out of money. for the next 20 years people had to go either up to richmond and around or take the long journey over the berkeley hills. in this time the oakland merchants exchange started to loose money to the port of s.f. or the port of Martinez due to the easy railroad access at both those points. the idea of a tunnel was revived in the 1890s by both counties and private investors. it was opened in 1903 but people called the tunnel different things. some people called it the kennedy toll road and some called it the old broadway tunnel. since its abandonment in 1927 it has been called the old broadway tunnel. at that time when it closed the portals were sealed off for public safety. when i went there you can tell where the tunnel used to be and on the west side there's a plack saying what it was and when it was. on the east side the sealed portal is in side an east bay regional park employee services entrance but there's no room to turn around at the end of the road so you have to drive in a bit but you can see where the tunnel was up to the left. if you know the bay area at all and if your in oakland drive up skyline drive and about half way up there will be a pull off with a tree and a flag poll in the middle and thats right where it is.

I was there with max13 when he went to this location. If you live or spend time in the hills, you've driven directly past the tunnel entrance. Once we found the Oakland-side entrance, we climbed farther up into the hill, before we found piles of HUGE planed beams (similar to what you see in old R/R's, mines, and the era of buildings where they could afford to fall and plane a 100' old growth tree ), and some sort of steam pump. From our location, it was easy to see where the tunnel had caved in, and it's path through the hills.

On the other side (the Orinda/Moraga side), the entrance is located within a rangers house, or a caltrans corporation yard, we're not quite sure, but it's somewhere over there.

I like stuff like this. Is camping allowed in the area? I would love to spend a day with a metal detector, if the law allows.

its called Tilden regional park. There is camping in the area during the summer and it used to be a military base during World War 2 so there's plenty of stuff to explore

It's amazing how stuff like this just kind of gets lost in time. Too bad there aren't more places like this around here. So basically the only way into what is left of this is through a regional park building? BTW, what is that in picture 2? I wanna say it looks like a trolly but I dont wanna sound too dumb .

From what me and bo2krocket man could tell it looks like an old steam pump of some sort. there's pistons in it so we were thinking some sort or ventilation

about 10 miles to the south is the old Antioch & Eastern (Later Sacramento Northern) train tunnel. On the east side of the hills is the eastern entrance on Pinehurst road and Shepard canyon on the west side. They were building houses on the west side in the 90's and opened the comcrete seal allowing us access. We went about 100 yards in and it was flooded, came back with rafts and went another 100 yards or so and it was caved. It seems like such a waste of a resource.
