Los Gatos Weighs $178M Highway 17 Fix, Demands Proof It Works

The Los Gatos Town Council spent its Sept. 15, 2026, special meeting examining a roughly $178 million plan to rebuild the State Route 17/State Route 9 interchange, a project pitched as relief from weekend beach traffic that spills onto town streets. No vote was taken at the study session. Instead, council members and residents pressed regional transportation staff on two questions that will decide the project's future: Will it actually work, and who pays?

• No guarantees on beach traffic: VTA staff project improvement but set no success target
• $18M local share questioned: Town's 10% match collides with tight budgets and pension worries
• Safety emerges as the strongest case: Separated bikeways, wider sidewalks replace dangerous cloverleaf ramps
• Blossom Hill Road overcrossing excluded, leaving a known substandard bridge unaddressed
• Draft environmental document nears release, opening the next public comment window

Council Wants Proof Beach Traffic Will Drop

The basics: The Santa Clara Valley Transportation Authority (VTA) proposes replacing the existing full cloverleaf at Highway 17 and Los Gatos-Saratoga Road with a "spread diamond" interchange. A spread diamond swaps looping ramps for straight ramps that meet the local road at traffic signals. The plan adds ramp metering on both on-ramps, auxiliary lanes between Los Gatos-Saratoga Road and Lark Avenue in both directions, and a northbound HOV preference lane.

Why it matters: Beach cut-through traffic is residents' top complaint. Support for town funding hinges on evidence that neighborhood streets will see fewer of those trips.

Where things stand: VTA Project Manager Chris Lilly said today's short weaving segments on the cloverleaf create a bottleneck. Removing the bottleneck, staff argued, would keep more beach traffic on the freeway and off local streets. The trade-off is two new signals at the ramp ends, which would add modest travel time on State Route 9.

Councilmember Mary Badame asked whether Los Gatos Boulevard, Main Street, Winchester Boulevard, North Santa Cruz Avenue and University Avenue were studied, and what reductions residents should expect.

"I need to know how this measurably benefits Los Gatos," said Badame.

Staff said those streets fell within a study area of about 19 intersections, and some intersections would see small increases in delay. Staff also said throughput through the interchange on beach weekends drops to about 3,300 vehicles per hour, compared with about 3,900 in a weekday evening peak. That gap is the capacity the project aims to recover.

"But I think we are promising an improvement for sure," said Lilly, who also said there are no promises or guarantees. Asked about success metrics, staff said no specific traffic redistribution target was set.

Council members raised gridlock in Almond Grove, Glenridge and other neighborhoods. They also noted that the study area ends near Winchester Boulevard and Route 85.

The other side: Planning Commissioner Rob Stumpf, speaking as a resident, framed his comments as encouragement rather than criticism. He called for baseline weekend cut-through counts and agreed-upon post-construction metrics, an approach he summed up as "trust but verify." Public commenter Tony Alarcon and public commenter Lee Fagot also asked for before-and-after measurements. Fagot questioned the basis for the claimed reductions and predicted the new signals would back up traffic. Public commenter Yamamoto said the project would not solve beach traffic.

Public commenter Jordan Moldo, a San Jose resident, supported the interchange but argued the long third lane is not worth the cost and may induce demand. Lilly said modeling showed "the aux lane actually had a bigger effect than the interchange reconstruction" on local-street traffic.

Decisions and stakeholder impacts: Council members praised the decision to skip a southbound HOV lane. That choice required a Caltrans design exception and is supported by the California Highway Patrol.

"I think the consideration not to have the HOV lane southbound makes so much sense," said Vice Mayor Maria Ristow.

Neighborhoods along beach routes stand to gain most if the modeling holds. Drivers on State Route 9 would absorb the added signal delay.

What's next: The project is in the Project Approval and Environmental Documentation phase. Technical studies are complete, and the draft environmental document is close to release, followed by a public comment period.

The $18M Question

Why it matters: The project is funded 90% by VTA's 2016 Measure B sales tax and 10% by the town. A 10% share of a $178 million project is roughly $18 million.

Where things stand: Commitments so far total about $13.2M from Measure B and roughly $1.4M from the town. Together, those dollars come close to funding final design. Right-of-way purchases and utility relocation remain unfunded, and the schedule runs through 2031.

"The 10% match does not have to be necessarily Town of Los Gatos funds," said Lilly. He explained that the match only needs to be non-Measure B money. Staff said local dollars are meant to leverage state and federal grants, though those programs tend to favor transit over highway projects.

Councilmember Matthew Hudes asked whether the town's match is 10% or 20%. He said meeting it would likely require a tax or revenue measure.

"We don't have $18 million or $36 million lying around," said Hudes.

Councilmember Rob Rennie suggested layering federal grants and getting the project shovel-ready before committing more. A shovel-ready project has completed design and environmental clearance and can begin construction quickly.

"We're not going to rush out and find $18 million to move this project ahead faster," said Rennie.

Mayor Rob Moore noted that VTA could help the town pursue grants.

The other side: Public commenter Richard Cannon opposed committing $20M or more. He urged the town to pay down unfunded pension liabilities first. Alarcon warned of runaway costs, noting estimates had climbed from $102M to $111M to the current $178M, and urged the town to limit its exposure. Yamamoto proposed a flat fee instead of a percentage share. Fagot objected to the town paying for state highways.

Decisions and stakeholder impacts: The town has not committed new money. Taxpayers face an open-ended percentage of a cost that has already risen sharply. A cap or flat contribution, as several speakers urged, would shift that risk back to regional and state partners.

Safety Makes the Strongest Case

Why it matters: Safety near the high school and on downtown connections gives the project a rationale that does not depend on the beach-traffic modeling.

Where things stand: Rennie said the presentation had underplayed safety, citing short sight lines, unpredictable lane changes and unsafe merges.

"In Los Gatos, we put a lot of value on safety, and we spent a lot of time talking about safety," said Rennie.

Staff agreed. They described removing free right turns, weaving segments and loop ramps, and cited a highway safety assessment showing improvement on local streets. The bike and pedestrian package includes:

• Class 4 separated bikeways
• Class 2 bike lanes that double as Caltrans shoulders
• 8-foot sidewalks
• A Class 1 path connecting to the Los Gatos Creek Trail

Staff said the bicycle "level of stress" rating would improve from 4, the most stressful, to 1.

"Those are all stellar safety improvements for sure," said Lilly.

Moore and Ristow both described their personal experiences with the interchange. Moore called himself an "enthusiastic supporter of trying to get this done."

The other side: Hudes asked whether the bike facilities could be trimmed to save money. Staff said the Class 4 bikeway is the vital element. Cannon argued that bike lanes are lightly used. Moldo backed the safety design but said banning right turns on red would be necessary. Staff said they were unsure whether turn restrictions would apply.

Decisions and stakeholder impacts: Students, cyclists and pedestrians stand to gain the most. Hudes signaled that the bike package could become a bargaining chip if costs force cuts. "Ultimately we may have to make some tradeoffs," said Hudes.

Blossom Hill Road Left Out

Where things stand: Hudes noted that the Blossom Hill Road overcrossing is not built to current standards, has been struck by a truck, and sits on student routes. He asked whether it could accommodate an added lane and whether it should be addressed as part of the project.

Staff said replacing the overcrossing would not reduce cut-through traffic and does not fit the project's stated purpose and need. Caltrans agreed to keep the bridge's existing, nonstandard vertical clearance.

"We are perpetuating that condition as far as the nonstandard vertical clearance at Blossom Hill Road," said Lilly.

Staff said approved shoulder widths will accommodate the town's separately planned pedestrian overcrossing at the site.

The other side: Alarcon and Fagot both raised the unresolved Blossom Hill issue during public comment. Fagot also flagged safety concerns during construction.

Minor Items

• Public commenter Gus Hu proposed a phased approach: add a stoplight and remove the two beach-side cloverleaf loops first. He said this would save about $20M.
• Public commenter Randy Chen, who lives behind the interchange, supported the project and asked whether sound walls are planned. His question went unanswered.
• Moore adjourned the session early because of a 7 p.m. meeting.

Looking Ahead

Moore asked that "VTA consider coming back in a year or sooner as this project continues to move along to update us again." Before then, residents' clearest chance to weigh in will be the public comment period on the draft environmental document, which staff said is close to release.
