Say "construction on Lomas Santa Fe" to anyone in Solana Beach and most people picture the same stretch: the crossing near Cedros, the light by the train tracks, maybe the run down toward Highway 101 where the Belly Up sits in its original Quonset huts. That's the part of the corridor that shows up in Google reviews and farmers market small talk. It is not the part that closes on October 5.
The mile that's actually getting torn up runs east of Interstate 5, from Santa Helena to Highland Drive at the city's boundary. That's the inland stretch that carries you to the schools, the library, and San Dieguito Regional Park rather than the beach. If your daily route stays west of the freeway, you may not notice a single cone this fall. If it doesn't, this is the project that's about to reshape your commute for the better part of a year.
What's Closing, and What Isn't
The Solana Beach City Council awarded a $7.4 million contract to Tri-Group Construction on May 27, chosen from a pool of six bidders, to build the eastern segment of the long-planned Lomas Santa Fe Corridor Improvement Project. Work is scheduled to begin October 5 and is expected to run about 11 months, wrapping by late summer 2027.
The one-mile scope covers new roadway paving, new sidewalks, a multi-use trail, dedicated bike lanes, landscaped medians, and pedestrian touches like benches and decorative paving, along with new traffic signals. Throughout construction, the city has committed to keeping at least one travel lane open in each direction, so this isn't a full closure. It's a slower, narrower version of the road you already drive.
What isn't happening yet is any work on the segment most people associate with "downtown" Solana Beach: the stretch from I-5 west to Highway 101, past Cedros and into the village. That phase, called Lomas Santa Fe West, is still in design. City leaders have said they plan to finalize that design next year, with a separate $3.5 million SANDAG grant already secured to help fund it. The mile near the coast gets its turn later.
Ten Years to Get Here
This project didn't appear on the council agenda overnight. Planning for the full Lomas Santa Fe Corridor began back in 2015, with a decade of community workshops, data collection, and design revisions behind it. Early concepts included roundabouts at points along the corridor. Those were eventually dropped in favor of a simpler design that keeps two through lanes in each direction, a decision that came only after years of public input.
Deputy Mayor Jill MacDonald has said the first council meeting she ever attended, back in 2018 and before she was elected, was a discussion of this same project. That's the kind of detail that tells you how long this has been on the city's radar. What changed this year wasn't the plan. It was the funding and the contract that finally turned a decade of meetings into a start date.
Why the Calendar Looks the Way It Does
The eleven months of construction weren't scheduled at random. City officials have said they identified specific non-working days built around the opening of the San Diego County Fair and the first week of the school year, timed to fall within the project window, specifically to avoid piling roadwork onto the days when traffic on this side of town is already heaviest. If you've ever tried to get anywhere near I-5 during Fair opening week, you understand the logic.
The $7.4 million construction contract sits alongside a separate two-year construction management agreement with Kleinfelder, worth roughly $979,000, to oversee the work and keep the schedule honest. A large share of the funding, $7 million, comes from a federal earmark Representative Mike Levin secured back in 2023 specifically for this corridor. The rest of the cost, and the western phase still in design, will draw on other sources including the SANDAG grant mentioned above.
Senior Civil Engineer Anda Wright has said the city plans proactive outreach before ground breaks, along with a dedicated hotline and email address for residents to flag problems once crews are on site. Updates on schedule and status are expected to run through the city's website and its regular newsletter rather than getting buried in a single announcement.
If You Bike This Stretch, Pay Attention
Lomas Santa Fe is one of the heavier bike corridors in the city, and that fact came up directly at the council meeting where the contract was awarded. Councilmember Dave Zito pointed to the earlier Coast Highway 101 project as a reminder that construction crews need to be agile and communicative when a corridor carries this much bike traffic, and he specifically asked that crews mark where cyclists are supposed to go once work zones start narrowing the road. If you ride this stretch to the train station or out toward San Dieguito Park, expect your usual line through traffic to shift week to week as different blocks come under construction.
That's a reasonable ask given what this project is actually building. The finished corridor adds a multi-use trail and real bike lanes where there currently aren't dedicated ones, which means the temporary disruption is in service of a permanent upgrade for exactly the people most inconvenienced by it in the short term.
The Part of Town That Waits
If you live closer to the coast, the practical takeaway is patience rather than rerouting. The design work on Lomas Santa Fe West won't be finalized until sometime next year, and construction on that segment hasn't been scheduled. The village, Cedros, and the run down to Highway 101 stay exactly as they are for now. The disruption belongs to the inland mile this fall, and the coastal mile gets its own timeline later, on its own contract, once the design is locked and funding beyond the SANDAG grant is in place.
For residents on either end of the corridor, the useful move is the same: watch the city's project page for the exact week-by-week schedule once work starts, since that's where Wright's team has said updates will actually live. A project a decade in the making rarely stays static once it starts moving, and the difference between a smooth October and a frustrating one usually comes down to knowing which block is under work before you leave the driveway.
None of this changes what makes this stretch of Solana Beach worth living in day to day. It just means the road connecting your house to the rest of town is finally getting the upgrade a decade of meetings promised, one careful mile at a time.
