The Tunnel Under Friars Road Finally Leads Somewhere

If you have ever walked past the pedestrian tunnel that ducks under Friars Road near the Escala community, you have probably wondered where it actually goes. For 17 years, the honest answer was: nowhere in particular. The tunnel opened in 2009 as a bridge to nothing more than the edge of Ruffin Canyon, where the trail dead-ended into rocky, overgrown terrain that even determined hikers usually turned back from.

That changed on Friday, April 17, 2026, when the City of San Diego cut the ribbon on a new stretch of trail through the canyon. The new construction is short, about half a mile, but it finally finishes what that tunnel started: a real, usable connection between Serra Mesa and Mission Valley that does not require a car.

What Actually Got Built

The project added three wooden footbridges, rerouted sections of trail along the canyon walls, and restored a stretch of wetlands that had degraded over the decades. On the Serra Mesa side, the trail begins near Taft Middle School on Gramercy Drive. On the Mission Valley side, it runs into a new trailhead inside the Escala community. Escala itself is gated, but the public tunnel under Friars Road still provides daylight access from the Fenton Marketplace shopping center, the same shopping center where the neighborhood's Costco sits.

The city paid for the work with Development Impact Fees and a grant from the California Natural Resources Agency, according to reporting from FOX 5 San Diego. Councilmember Raul Campillo, who represents Serra Mesa on the San Diego City Council, joined the ribbon cutting alongside city park rangers and the volunteers who had spent years pushing for it.

Why a Half-Mile Trail Took Nineteen Years

The person most associated with the project is Kevin Johnston, a Serra Mesa resident and longtime volunteer with Friends of Ruffin Canyon. Notes he kept on the effort go back as far as 2007. Here is roughly how the next two decades unfolded:

1. 2008 — Friends of Ruffin Canyon and Friends of Normal Heights Canyons began working with the San Diego River Conservancy to study possible trail routes connecting both sides of Mission Valley.
2. 2009 — The pedestrian tunnel under Friars Road opened, built with the assumption that a continuous trail would eventually meet it. It did not, not for a long time.
3. 2010 — The San Diego River Conservancy published its feasibility report.
4. 2013 — A California Environmental Quality Act draft analysis followed, and the project stalled again.
5. 2014 to 2015 — The Serra Mesa Planning Group got involved, approved the use of Development Impact Fees toward permitting costs, and the initiative finally landed with the City of San Diego.
6. April 2026 — Construction wrapped and the trail opened to the public.

Johnston described the wait bluntly at the ribbon cutting: "Sometimes I thought it would never happen, you know? But this is just one of the greatest days I've had in years." Part of the delay, by his own account, came from the Escala homeowners association, which initially resisted the trail before eventually helping build community support for it.

Peter Hulburt, director of the San Diego Mountain Biking Association, one of the groups that helped see the project through, put it in terms of who actually benefits: "This is a win not just for our organization only, but for so many trail users who live and play here."

What the Canyon Has Been Hiding

Ruffin Canyon is older than any of the paperwork that delayed it. Supervising Park Ranger Carey Goldstein led a walkthrough for media and residents on opening day, pointing out that the canyon was once a cobble-filled creek bed and long served as territory for the Kumeyaay Nation. Goldstein highlighted a wild cucumber vine growing along the path, explaining that the Kumeyaay used its toxic seeds to stun fish in shallow pools, a small piece of local history that most people driving past on Friars Road would never guess is sitting a few hundred feet below the road grade.

The restored sections now support native plants including monkey flower, lemonade berry, California sage, broom baccharis, and San Diego County sunflower. San Diego Canyonlands, which has run cleanup workshops in the canyon for years, continues to organize volunteer days to keep invasive species out.

How to Actually Use It

For residents planning a first trip through, the practical details matter more than the ribbon-cutting speeches:

• The trail is open to hikers as the primary use, with cycling permitted.
• The Serra Mesa entrance sits near Taft Middle School at 9191 Gramercy Drive.
• The Mission Valley entrance sits inside Escala, reached through the public tunnel from the Fenton Marketplace shopping center during daylight hours.
• Because Escala is a private, gated community, the tunnel and trailhead are the only public access points into that side of the canyon.
• Yes, this means the walk doubles as a legitimate route to Costco. Multiple outlets reporting on the opening noted this as one of the more popular practical upshots for Serra Mesa residents.

What This Means for Daily Life Here

Before April, the honest way to describe travel between Serra Mesa and Mission Valley on foot was that it did not really exist. The canyon was there, the tunnel was there, but the gap between them made the whole thing pointless for anyone but the most stubborn hikers. Now there is an actual through-route, with infrastructure built for it, native habitat restored around it, and a coalition of neighbors, city staff, and advocacy groups who spent the better part of two decades making sure it would hold up.

That is the kind of change that does not show up on a map update or a press release headline. It shows up the next time you decide to walk to Costco instead of drive, or take the long way to a friend's place in Mission Valley just to see what the canyon looks like in spring bloom.
