Wagon Wheel Crossing Bridge Fundraiser

The Issue

The swing bridge at the Wagon Wheel Crossing at the western end of the Los Penasquitos Canyon Preserve is in need of rebuilding.  This is a major north/south crossing in the canyon and experiences over 4,000 crossings by mountain bikers, hikers, and trail runners per month. 

What do we need?

$20,000 is needed to completely rebuild the bridge. The bridge would be similar in design as a swing bridge, but to higher, more sustainable standards with better materials. 

What's in it for you?

All donations make a difference and are greatly appreciated. A donation of $2,500 will get your name or your business name routered onto a bridge plank and the long-lasting feeling of philanthropic bliss.

With your help and our partners at the City Of San Diego, we will rebuild the swing bridge at the Wagon Wheel Crossing beginning this fall. This will offer trail users better accessibility and create a better outdoor experience for all.

Help us reach our goal of $20,000 and improve our community!

Fund Raising Progress

Current State Of The Swing Bridge at the Wagon Wheel Crossing

The San Diego Mountain Biking Association is a 501(c)3 Nonprofit

Our work is supported by generous donors like YOU!  

We are gearing up for a very busy 2021-22 Trail Work season on projects throughout the county from Mount Laguna to Daley Ranch to Chula Vista and more!  When you donate to this general fund, we promise to use your gift where it's needed most.  Whether that's covering operating costs, clearing a fallen tree, or buying a shovel for a volunteer to use, we'll make sure your money has the most impact on our trails and our community.  

Past contributions and grants have allowed us to purchase and maintain a mini-excavator, a motorized wheelbarrow, a plate compactor, a water buffalo and water distribution equipment,  and loads of hand tools and materials to help us maintain and build trails.  In addition, your support provides resources for our staff and our volunteer trail experts to partner with user groups, land managers, and policymakers to improve access and your trail experience.  Learn more about current projects here past projects here.
