Laughlin Road Bridge

Have watched this bridge continue to crumble for two decades. It is in a terrible state today. Wondered why this has been ignored so long and is not scheduled for repairs. After some research, I see now that Sonoma County TWS has diligently tried to fix the existing or build a new bridge. Has been held up without progress for over 10 years! Hope to see progress on this bridge project soon. Losing this route and preventing repairs to the existing bridge hurts the greater community.

The Laughlin Road Bridge has had its share of abuse due to the increase of traffc into the airport business area and people's disregard for wildlife in the creek. Over the last 2 years there has been an increase of traffic during the peak hours as well as a significent amount of oversized trucks attempting to drive over the bridge. The CHP has been called out at various times of the day to assist the truck drivers off the bridge and re-route them back to River Road. I've witnessed an oversize truck tie-up the bridge for over 4 hours. The Mark West Creek that flows below the bridge has been the home to various fish, turtles and once an otter that came through. The Mark West Creek along with the Laughlin Bridge continues to offer a unique beauty that we consider our backyard.
