The concrete bridge that carries Coast Highway 101 over the San Elijo Lagoon inlet sits just south of the San Elijo State Beach campground. It has two vehicle lanes in each direction, a protected bike lane on each side, and a pedestrian walkway along each edge. The west walkway has the ocean view, and the Union-Tribune reports it draws more walkers than the east side even though it is the narrower of the two.
In September, an engineering assessment of all 46 bridges in Encinitas gave this one a "poor" rating. The headline sounds alarming, but the grade is mostly paperwork. The rating is what qualifies the bridge for federal repair money. The open question is whether that repair leaves the ocean-side walkway as narrow as it is today. That depends on whether Encinitas decides to pay for the widening itself.
What the inspectors found, and what "poor" means here
In January, the City Council awarded Kleinfelder, Inc. a $270,000 contract to evaluate every bridge in the city and write a 10-year repair plan. The firm looked at nine conventional bridges, 11 culvert structures and 26 pedestrian-only structures. Inspections ran from February through April 2026. The final report was finished in August and went to the Council on September 9.
Inspectors sounded concrete with hammers and measured cracks and delaminations. The report says the lagoon bridge is "showing signs of deterioration," including chipped concrete and rusting rebar. Kleinfelder engineer Kelly Burnell told the Council that "poor doesn't mean unsafe." It means the bridge needs repair work. The city's own meeting recap says the same about both poor-rated structures: neither was considered unsafe or at risk of collapse.
The other poor-rated structure is a pedestrian bridge over a drainage swale at Leucadia Oaks Park. The report also flagged a Town Center Drive bridge over a tributary of Encinitas Creek. It is rated "fair" for now, but it could drop to "poor" if its corrosion speeds up. Most of the city's bridges came back satisfactory or better, which is how The Coast News ran the story.
The rating matters because a "poor" condition status makes the lagoon bridge eligible for a Federal Highway Administration funding program.
A rating the city has been working with since 2019
The September assessment didn't start anything new. It confirmed a process that has been running quietly for years. The bridge has a long record of patch repairs:
- 1934: Original reinforced concrete pile bridge built.
- 1953: Widened on the western side.
- After 1993: Repairs to the pile extensions of the original bridge.
- Fall 2019: City staff met with Caltrans engineers, who said the bridge was a good candidate for the Highway Bridge Program.
- June 2020: Protected bike lanes with wheel stops and bollards newly installed through Cardiff.
- June 24, 2020: Council authorized the city to apply for, accept and administer federal Highway Bridge Program funds.
- 2022: Repair to the northeast abutment.
- June 14, 2023: Council appropriated the first grant money for environmental review and project approval.
The Highway Bridge Program is funded by the Federal Highway Administration and run by Caltrans's Local Assistance Division. It covers locally owned bridges that the state and federal government find to be in poor condition and important for traffic. The September report says rehabilitation of the lagoon bridge "has already begun the design phase."
The local share keeps changing
Cost is where the record gets less clear. In 2023, staff described the job as a $17 million rehabilitation. Encinitas would cover 11.47 percent and federal funds would cover the rest. The September 2026 report uses a larger number for the city's share. Three public sources give three different figures:
| Source and date | City match for the lagoon bridge | What it covers |
|---|---|---|
| City staff report, June 2023 | About $1.96 million | Total match over an eight-to-ten-year project life |
| Union-Tribune, Sept. 13, 2026 | About $3.5 million | Matching money alongside grant funds for repairs |
| City bridge assessment report, Sept. 2026 | $3.8 million | Local match for design and construction, part of a $5.9 million 10-year program |
None of these sources explains the gap between the figures. They may describe different phases or estimates made at different times. The 2026 numbers assume 5 percent cost escalation for each fiscal year after Year 1, and the report calls them "preliminary in nature." Either way, this bridge is the biggest single item in the city's bridge budget for the next decade. The 10-year program puts $400,000 toward it in Year 1 and $3.4 million in Year 5. Nothing else on the chart comes close in any one year.
The Year 5 entry is a budgeting slot, not a scheduled groundbreaking. The best public timing estimate comes from Engineering Department Director Dan Nutter. He told the Council it could be about five years before construction starts. "This is an arduous process," Nutter said. "It is going to take us some time."
Repair versus betterment, and the west walkway
Part of what makes the process slow is that Encinitas and Caltrans have to agree on the project's scope. According to Nutter and others, the main issue is which work counts as "repair" and which counts as "betterment," meaning improvements to the structure.
The difference decides who pays. Repairs are covered by the grant plus the city's match. Major improvements fall outside that. Widening the narrow pedestrian walkway is one example, and Nutter said Encinitas would have to pay the full cost of it.
That puts the most-used part of the crossing in the most expensive budget category. The ocean-view west walkway is the narrower side, and making it wider counts as a betterment. Under the grant, the city gets federal help to fix the concrete and rebar. A wider path for the people walking to Cardiff Reef would come from the city alone.
Councilmember Joy Lyndes represents the Cardiff area that includes the bridge. She told the Council that, given how many pedestrians and cyclists cross every day, there's no doubt residents will want betterments. She also argued for doing them at the same time as the repair work:
"We're probably never going to have a better opportunity."
Her point is about timing. The bridge was widened once, in 1953, and has only had patch repairs since. A federally funded rehab is the one time the city is already working on the structure and already paying a share of the cost. Adding the walkway now means sharing crews, permits and a construction window with work that is happening anyway. The September report gives no cost for widening the walkway, and none of the sources says whether the Council has committed to paying for it.
Crossing it this fall
For now, the bridge looks the same as it did in August. The city's March 2026 project page says Caltrans last inspected it in 2024. That page describes the east side as the ADA sidewalk, alongside four travel lanes and a protected bike lane in each direction. On the north side, San Elijo State Beach's campground is at 2050 South Coast Highway 101, and the state park extends north from the lagoon entrance channel. Pacific Coast Grill is nearby at 2526 Coast Highway 101, next to Cardiff State Beach and Cardiff Reef. Chart House is at 2588 South Coast Highway 101 and Las Olas is at 2655 South Coast Highway. The Cardiff Kook, officially titled "Magic Carpet Ride," stands at South Coast Highway and Chesterfield Drive.
The city's own recommended Cardiff beach walk is a 2.36-mile round trip from Cardiff Reef to Seaside Reef. It passes the campground and the San Elijo bridge, with surfers and stand-up paddleboarders out at Cardiff Reef. Kleinfelder's full assessment is public on the city's meeting portal. The city tracks the project on its San Elijo Bridge Rehabilitation page, which is where updates on scope and the walkway decision are likely to show up first.
A five-year public works schedule on the main road through Cardiff is the kind of thing that changes how people plan around a house near the bridge.
