Recently my dad and I went over to Bridgeport to see the covered bridge. It is the longest single span covered bridge in all of the USA. It was built in 1862 by David Isaac Johnwood and was built for the Virginia Turnpike Company toll road which served the northern mines and the busy Nevada Comstock Lode. You can read more about its history in the picture.
This is an amazing piece of Northern California history and if you have the time this year, you should drive up and see it. The drive up from Sacramento only takes 90 minutes and it is so worth it. This is how you get there:
From Sacramento head up HWY 80 to Auburn and take the HWY 49 exit (exit 119c Elm Ave.)toward Nevada City.
Head north and follow 49 to the CA-20 west/Empire St. toward Marysville, 22 miles, turn left onto CA-20.
Then go 7 and a half miles and turn right onto Pleasant Valley road. The bridge is about 8 miles in.
You will have a great time.
