Drivers coming back to Golden Avenue will find the same number of lanes they left in February. The 1934 bridge over the Carbon Canyon Creek Channel had two traffic lanes, and the replacement has two as well. The rest of the 2026 bridge was designed for people who aren't in cars. The old span had no sidewalks and no bike lanes, so motorists, pedestrians and cyclists all shared the same roadway.
The City of Placentia will mark the bridge's return with a reopening celebration on Wednesday, Nov. 4, at 10 a.m., held at the bridge itself. The city describes the event as celebrating "the renewal of an important connection between Placentia and Yorba Linda." For most of this year, that connection ran through the detour on Valencia Avenue, McCormack Lane, Bastanchury Road and Rose Drive. Once the bridge is back in service, Golden Avenue has a crossing that someone on foot, a parent with a stroller or a teenager on a bike can use without stepping into traffic.
Same lanes, a different bridge
The bridge sits right at the Placentia and Yorba Linda line, east of California Street and west of Rose Drive, north of Brooklyn Avenue and south of Imperial Highway. The 1934 structure had been rated functionally obsolete by Caltrans since 2005, according to a March 2025 briefing from Placentia's City Administrator. Comparing the old bridge with the new one shows where the money went.
| 1934 bridge | 2026 replacement | |
|---|---|---|
| Vehicle lanes | Two | Two, each 12 feet wide |
| Sidewalks | None | New sidewalks |
| Bike lanes | None | New bike lanes |
| Center of the road | Not listed | Striped center median |
| Edges | Not listed | Hand railings |
The city's closure notice lists grading, drainage, utility and roadway improvements in addition to the bridge deck. The city says the work results in "safer and more efficient travel for motorists, cyclists, and pedestrians." Placing cyclists and pedestrians next to motorists in that sentence matters on this stretch, because the old bridge gave them no space of their own.
Who paid for the crossing, and how the total moved
The funding plan also shows what the bridge is meant to connect. The City Council's Nov. 18, 2025 agenda lists four funding sources:
- $2,200,000 in Community Project Funding, also called Congressionally Directed Spending
- $2,647,046 from the Highway Bridge Program
- $215,682 from the County of Orange as an OC Loop Segment D contribution
- $974,871.55 from Measure U, which includes the city's required federal match
The county's contribution is tied to OC Loop Segment D, the regional trail planned to run beneath the bridge, which the next section covers.
The total cost changed over the course of the project. The March 2025 briefing estimated about $5.5 million. By November 2025, the council agenda listed a total budget of $6,037,599.55. That figure included a $4,687,010.50 construction contract with CT&T Concrete Paving, a $468,701.05 contingency, $713,091 for construction management and inspection, and $168,797 for construction engineering. On Sept. 8, 2026, the council voted 5-0 to approve an additional $302,848 for T.Y. Lin International to continue construction management and inspection. That brought T.Y. Lin's contract to $1,015,939 and the total project budget to $6,375,873.55.
In the September record, the federal, Highway Bridge Program and county amounts are unchanged. The Measure U line rose to $1,313,145.55. That is $338,274 more than in November 2025, the same amount the total budget grew over that period.
The timing changed too. The January closure notice planned a full closure from Feb. 19 through Sept. 11 and noted that construction schedules could change because of weather or other factors. The Nov. 4 celebration comes about eight weeks after that original end date.
What runs under the new bridge
The Carbon Canyon Channel under Golden Avenue is the route for OC Loop Segment D, a short piece of trail that fills a gap in what OCTA describes as a 66-mile regional bikeway. According to a City of Yorba Linda resident notice from April 2025, Segment D is about 0.67 miles long, passes through Yorba Linda, Placentia and Brea, and mostly follows the channel. It links the El Cajon Trail near Bastanchury Road with the La Floresta Trail near Imperial Highway and La Floresta Drive.
The design firm's project description lists a 12- to 15-foot-wide bikeway with an undercrossing at Golden Avenue. It also lists lighting, fencing, landscaping, ADA access, and bicycle and pedestrian signals and beacons. That puts the trail and the new bridge at the same spot. The bridge carries people across the channel on Golden Avenue, and the bikeway passes underneath along the channel.
The trail's timeline is less certain than the bridge's. In June 2024, the County of Orange's Board of Supervisors received a staff recommendation for an $11,880,205 construction contract with a 330-working-day schedule. In a July 2025 road closure alert, OC Public Works said construction was nearing completion. OCTA's OC Loop page still lists Segment D under "Continued Progress," with completion scheduled "by the Winter of 2025." Segment D does not yet appear in OCTA's list of completed segments. The county has not announced an opening date. Until it does, plan on using the bridge's sidewalks and bike lanes, and treat the channel trail below as coming but not yet open.
The bridge opens a busy stretch of the Placentia calendar
The Nov. 4 ceremony starts a month of city events, several of them part of Placentia's Centennial year. All of these dates come from the city's Oct. 22, 2026 City News newsletter and its online calendar.
| Date | Event | Where |
|---|---|---|
| Wed., Nov. 4, 10 a.m. | Golden Avenue Bridge reopening celebration | Golden Avenue Bridge |
| Wed., Nov. 11, 10 a.m. | Veterans Day Ceremony | Placentia Civic Center Courtyard, 401 E. Chapman Ave. |
| Sat., Nov. 14 | Centennial Pickleball Tournament | Tuffree Park |
| Nov. 25–26 | City facilities closed for Thanksgiving | Citywide |
| Sat., Dec. 5 | Centennial Birthday Bash | Champions Sports Complex, 505 Jefferson St. |
The newsletter lists the Birthday Bash from 1 to 9 p.m., with carnival activities, entertainment, food and a drone show. The city calendar lists the same event from 4:30 to 10 p.m. Check the calendar again closer to Dec. 5 before planning around a start time.
The same newsletter has news from the south end of town. Juan Pollo is opening its 26th location at Cobblestone Village, 2095 E. Orangethorpe Ave., at Orangethorpe and Lakeview avenues. Bonn Coffee is opening its first location next door. Juan Pollo was described as almost finished, with a grand opening expected soon. Bonn Coffee was still in plan check for interior work, with construction expected to start shortly. Bonn Coffee plans pistachio lattes, espresso drinks, pastries and milk cakes. The two will join Esther's Taco House and Madres Brunch, which are already in the center. Neither business has announced an opening date.
To attend the Nov. 4 ceremony, head to Golden Avenue between California Street and Rose Drive, where the bridge crosses the channel at the Placentia and Yorba Linda line.
