Cyclists heading south along the L.A. River bike path hit a dead end at Egret Park, forced onto high-traffic streets through Lincoln Heights, Chinatown, downtown Los Angeles and Boyle Heights before the trail picks up again miles later. That eight-mile missing link between Elysian Park and Maywood has ballooned into one of the most expensive per-foot infrastructure gaps in the region, with current cost estimates now topping $1 billion — nearly $24,000 for every single foot of trail.
The project, which would eventually connect the western San Fernando Valley to Long Beach, is led by the Metropolitan Transportation Authority and remains, as the Los Angeles Times put it, mired in planning and bureaucratic complications. Voters approved a half-cent sales tax for transit projects in 2016, and that Measure M package earmarked $365 million for the L.A. River Path — a sum that looked adequate at the time but has been dwarfed by rising costs tied to rail crossings, historic bridges and elevated construction through dense urban neighborhoods.
Cost Overruns Trace Back Years
The shortfall isn't new. LA Metro board reports from November 2021 show that early 15% preliminary engineering estimates already put the project between $392 million and $486 million in 2021 dollars — a $142 million gap beyond the Measure M allocation, years before estimates would cross the billion-dollar mark. Metro's unforeseen-expense reserve for the project grew from $75 million to $309 million in 2025 alone, according to the Times, underscoring how much financial uncertainty still surrounds the corridor.
Much of that cost comes from the physical reality of building through one of the city's most industrialized corridors. In a January 2026 regulatory review letter, the California Public Utilities Commission Rail Crossings Engineering Branch warned Metro that the path must navigate grade-separated crossings alongside active freight and passenger rail lines operated by Metrolink, Amtrak, Union Pacific, BNSF and Metro's own Division 21 light rail facility. Construction also faces active rail lines and historic bridges along the route, and proposed designs include seven pedestrian bridges plus elevated sections supported by beams to clear the tracks safely.
Olympic Deadline Already Slipped Away
The project was once part of Metro's “Twenty-Eight by ’28” initiative meant to deliver major transportation upgrades ahead of the 2028 Olympic and Paralympic Games. Metro pulled the eight-mile gap from that priority list in March 2024, as the overall Olympic project budget shrank from $43 billion to $20 billion amid unresolved questions over who would operate and maintain the finished trail, according to BikinginLA. The path was originally supposed to open sometime between 2025 and 2027; Metro staff now expect groundbreaking in about two years, with the initial phase estimated for completion in 2031 — well after the Games have come and gone.
Governance, not just money, has been the sticking point. Metro acts as the funding and planning lead, but the City of Los Angeles and LA County have resisted taking on long-term operational and maintenance liability for what would be an elevated path structure running through their jurisdictions, as Streetsblog LA reported. On May 28, the Metro Board — chaired by Mayor Karen Bass — approved a joint motion authored by Bass and Supervisor Hilda Solis directing staff to work with the city, the county, the LA County Flood Control District and the U.S. Army Corps of Engineers on a formal Governance Model Study aimed at resolving the standoff. Metro staff are reviewing public comments on the draft environmental impact statement and plan to recommend a path forward this fall.
Mayor's Office Points to Progress
Bass’s office told the Times that the mayor is marshaling resources to eliminate distractions threatening the project’s pace and cost. Proposed designs have already responded to community input and comments from the Army Corps of Engineers and the LA Department of Water and Power, and Metro dropped a less expensive river-level route option, citing safety concerns.
That cheaper alternative — running near the flowing river itself rather than elevated above it — remains a flashpoint among advocates. The “Festival Trail” campaign presented engineering analyses by GeoSyntec in May showing sensor-based flood warning systems could give cyclists more than four hours of advance notice before channel inundation, which proponents say would let a lower-cost in-channel path operate safely 96% of the year, or unusable for fewer than 20 days annually. Metro rejected that approach, pointing to the risk that the route would be unusable during heavy rains.
What's at Stake for Nearby Neighborhoods
The corridor cuts through Chinatown, Lincoln Heights, Boyle Heights, Maywood and Vernon, and the stakes for residents are significant. About 1 million people live within three miles of the project corridor, and the proposed path would serve 76,000 residents within walking distance, according to Metro planning documents. Working-age people within bikeable distance of the route currently use walking, biking or transit for about 17% of their regular commutes, per the Times' reporting.
Developer Yuval Bar-Zemer, who has spent $350,000 of his own money on engineering studies and advocacy for the project, said the benefits of finally completing the path are obvious. Urban planning advocate Michael Schneider described the unfinished stretch more bluntly, calling it a huge chasm in the middle of what should be a continuous 32-mile active transportation corridor.
Progress elsewhere on the broader river path network has moved faster. The separate 12-mile San Fernando Valley segment, managed by the City of Los Angeles, secured an additional $10 million in Measure M funding from Metro in September 2025 to supplement its original $60 million allocation, as the city re-bids construction contracts between Canoga Park and Studio City to lower costs. Just north of the stalled downtown gap, the city opened the $20-million, 400-foot Taylor Yard Pedestrian and Bicycle Bridge in Elysian Valley back in March 2022, giving cyclists a car-free crossing between Cypress Park and Frogtown — a small but tangible piece of the puzzle already in place while the billion-dollar middle section waits on Metro's fall recommendation.
