Pacific Coast Highway Through Malibu Is Getting a $69 Million Rebuild: Your Guide to the Lane Reductions and the Drive

Introduction: The Malibu Coast Road Gets Its Overdue Rebuild

Starting Tuesday, October 27, the most famous commute-and-cruise road in Los Angeles changes for years. Caltrans begins a $69 million pavement rehabilitation of Pacific Coast Highway, State Route 1, through Malibu, and drivers will meet lane reductions, grinding machines, narrowed lanes, and reduced speed limits on weekday daytimes between Cross Creek Road and the Ventura County line.

This is not a closure. Caltrans is clear that at least one lane stays open in each direction, with no full closures planned. It is a long, slow rebuild of a road squeezed between the Santa Monica Mountains and the Pacific. Plan around the work hours and PCH remains a great drive. Ignore them and a 40-minute Malibu run can easily take twice that.

What Happened: $69 Million, 63 Lane Miles, Starting October 27

Caltrans announced the project this month and construction signs have already gone up along the corridor, including covered shoulder-closure signs near Pepperdine University, where local reporting says the first work is expected to begin. The official Caltrans project page for the PCH pavement rehabilitation defines this first segment as Cross Creek Road to the Los Angeles County and Ventura County line in Malibu, rehabilitating about 63 lane miles for $69 million, with construction running from fall 2026 into spring 2030. The contractor is Chumo Construction Inc. of Baldwin Park, and Caltrans describes the work in its news coverage as continuing through winter 2029-30.

The scope is more than a repave. Crews will grind and replace crumbling pavement across the full width of the highway, upgrade guardrails, install ADA-compliant curb ramps, improve lighting and traffic signals, update signage, add fresh striping, build sidewalks at bus stops, and add Class II bike lanes and pedestrian warning signs. In places, local reporting says medians and traffic lanes will be narrowed while bike lanes are added.

Work runs Monday through Friday from 6 a.m. to 3 p.m., weather permitting, with lane reductions, slower work-zone speeds, and noise and grinding for nearby homes and businesses. Local reporting notes the pavement was last fully repaved around 2010 and calls the project years overdue.

This is also only phase one. A second, $85 million segment from the McClure Tunnel in Santa Monica to just south of Cross Creek Road is planned for late 2027 to late 2030, taking the combined program to about $154 million and 120.6 lane miles. Knowing the work window, not avoiding Malibu, is the right strategy.

The Drive: Santa Monica to the Ventura County Line, 27 Miles of Malibu

The classic run heads northwest from Santa Monica, where PCH leaves the McClure Tunnel, then follows Malibu's full coastline to the Ventura County line. The rebuild segment is the northern two-thirds, from Cross Creek Road westward. Drive it outside the weekday work window and the experience is unchanged: ocean on your left, mountains on your right, a beach name every mile.

Stops worth building the drive around, east to west:

• Malibu Lagoon and Surfrider Beach — the start of the work zone, where Malibu Creek meets the surf break that helped invent California surf culture. Check the official Malibu Lagoon State Beach page for current park and parking conditions before you go.
• Malibu Pier and Carbon Beach — the wooden pier, the public walkway past the famous beachfront houses, and an easy lunch stop before the road turns rural.
• Pepperdine University and Malibu Bluffs Park — the landmark campus and, across the highway, one of the best free ocean viewpoints on this coast. The first construction signs appeared here, so expect shoulder work here first.
• Point Dume and Zuma Beach — headland trails at Point Dume and the wide, lifeguarded sand at Zuma.
• El Matador State Beach — sea stacks and small coves down a steep path. Caltrans notes it is also supporting city-led roundabout work near El Matador, so watch for changed traffic patterns on future visits.
• Leo Carrillo State Park — the last big beach before the county line, with tidepools, a campground under the sycamores, and the feeling that the city has finally let go.

If this pattern of a famous stretch of Route 1 getting narrower before it gets better sounds familiar, it is. Further south, a crack in the bluff has already narrowed the highway in our guide to Pacific Coast Highway near Laguna Beach, and further north the same highway spent three years in landslide repair in our guide to Highway 1 through Big Sur. Malibu's version is planned, funded, and announced in advance, which makes it the easiest of the three to drive around if you time it right.

Practical Tips for Driving It During Construction

1. Drive outside the work window when you can. Lane reductions run Monday through Friday, 6 a.m. to 3 p.m. Early mornings before 6, late afternoons, evenings, and weekends avoid the active grinding and paving, though signs and narrowed sections remain.
2. Check conditions the morning you go. Use Caltrans QuickMap for the live lane closures, incidents, and message signs on State Route 1, and check again before the return trip, because a beach day ends right as conditions change.
3. Use the canyon detours for through trips. If you are commuting between the Valley and the coast and do not need the beach, Malibu Canyon Road, Kanan Dume Road to U.S. 101, and Topanga Canyon Boulevard, State Route 27, are the practical alternatives when PCH backs up at Pepperdine or Cross Creek.
4. Slow down and merge early in the work zone. Speed limits are reduced where crews are working, flaggers and traffic control will be in effect, and at least one lane each way stays open, so the delay is measured in patience, not in a closed gate.
5. Give cyclists and pedestrians new room. This project adds bike lanes, sidewalks, and ADA ramps to a highway that previously gave both groups almost nothing. Expect people outside cars in places you are not used to seeing them.
6. Expect noise if you are staying on the corridor. Caltrans warns residents and businesses near the work may hear grinding and feel vibration during work hours. A beach house rental on PCH is still wonderful, just not quiet at 7 a.m. on a Tuesday.

When to Go

For a pleasure drive, go on a weekend, or on a weekday after 3 p.m. for the golden-hour run west when the crews are gone. Fall and winter outside work hours bring the emptiest road and clearest air. Summer remains busiest regardless of construction.

If Malibu is a through route rather than a destination, build the detour decision into your routine now. This project runs into 2030, so checking QuickMap before a PCH trip is a habit worth forming this week.

The Bottom Line

Pacific Coast Highway through Malibu stays open, and from October 27 it starts becoming a better, safer road: new pavement, better guardrails and signals, real bike lanes, and crossings that work for everyone. The price is weekday daytime lane reductions from Cross Creek Road to the Ventura County line for years, not weeks. Time your drive outside 6 a.m. to 3 p.m. on weekdays, use the canyon roads when you are just passing through, and the 27 miles of Malibu remain what they have always been: the front porch of the California coast, now finally getting repaired.
