Downtown Boca's Federal Highway Rebuild Takes Lanes From One Short Stretch, and That Stretch Is Under Construction Now

Northbound drivers on Federal Highway between Camino Real and SE 5th Street have been down to a single lane this month. According to the Florida Department of Transportation's weekly Palm Beach County traffic report for October 2 to 9, 2026, that one-lane reduction runs through October 16 to make room for drainage work and roadway repurposing. At the Camino Real intersection, one northbound and one southbound lane are closing on and off from 8:30 a.m. to 4 p.m. through Friday, October 9, for signal work.

These are the first visible changes from FDOT's S.R. 5/U.S. 1 Lane Repurposing and Resurfacing Project. The project covers 1.3 miles of Federal Highway from Camino Real to NE 8th Street/NE Mizner Boulevard. It started August 20, 2026, and the state's latest estimate puts completion in late 2027. Most people describe it as "the lane cut." But the permanent loss of travel lanes is limited to the southern end of the corridor. Across most of the 1.3 miles, drivers keep the lanes they have today, and the new bike lanes are carved out of the median.

Two Segments, Two Different Projects

FDOT's scope splits the corridor at SE 5th Street/SE Mizner Boulevard, and the work on each side is different.

The Palm Beach TPA's US-1 Multimodal Corridor Study made the lane-reduction recommendation for that southern piece only. It recommended converting the six-lane section between Camino Real and SE Mizner to four lanes with separated bike lanes, and it measured the section at about three-tenths of a mile. So the driving lanes go away on roughly a quarter of the project length. North of SE 5th Street, through Sanborn Square and past Mizner Park, the road keeps its lanes and gets narrower in the middle.

Where the Lost Lane Goes, Foot by Foot

The southern segment is the part that will look most different in 2027. The Coastal Star reported in September 2026 that this stretch now has 6-foot sidewalks and 4-foot bike lanes with no buffer. Here is how the paper described the new layout, from the travel lanes out to the property line:

• Raised concrete strip, 2 feet wide, separating cyclists from moving cars
• Sod strip, 2 feet wide, next to the concrete
• Separated bike lane
• Sod strip, 4 feet wide, between the bike lane and the walkway
• Sidewalk, 11 feet wide, almost double today's 6 feet

The sources give different widths for the bike lane. FDOT's project page says the separated bike lanes are 7 feet wide. The Coastal Star says 5 feet. A 5-foot riding surface plus the 2-foot raised concrete strip adds up to 7 feet, which would explain the gap, but FDOT's 7-foot figure is the official specification.

The speed limit inside the project limits will stay at 35 mph, according to FDOT.

The One Place Drivers Gain Capacity

Camino Real is the exception. This is the intersection where many drivers from the south end of downtown leave Federal Highway, and FDOT is adding a second northbound left-turn lane there "to improve intersection operations and capacity." The existing signals are also being replaced with mast arms. That signal work is what is behind the intermittent closures at Camino Real this week.

The 2018 corridor study shows why planners were comfortable with four lanes on the southern stretch. Its highest forecast for that 0.3-mile section was 1,400 vehicles per hour per direction at peak hour in 2040. That number is a forecast for 2040, not a current traffic count. The sources we reviewed include no recent measured count for this segment.

A Construction Clock Built Around Rush Hour and Event Days

The work began at the south end. The Coastal Star reported that the inside lanes in both directions between SE 8th Street and SE 5th Street closed from August 24 through September 11.

From here on, FDOT's posted rules control when lanes can close. On the southern segment, one lane can close at any time in either direction. Two-lane closures are limited to non-peak hours on non-event days, nights, and weekends:

• Northbound, two lanes: 10:30 a.m. to 4:30 p.m., and 6:30 p.m. to 7:30 a.m.
• Southbound, two lanes: 7:30 p.m. to 12:30 p.m.

On the northern segment, the rules are stricter. Only one lane can close, and only in these windows:

• Northbound, one lane: 7:30 p.m. to 8 a.m.
• Southbound, one lane: 7:30 p.m. to 11:30 a.m.

FDOT also states that access to businesses and residences will be kept open throughout construction.

The phrase "non-event days" matters this fall, because three November events sit on or right next to the northern segment:

1. City Night Market, Thursday, November 5, 6 to 9 p.m., at Sanborn Square, 72 N. Federal Highway. The City is providing free BocaConnect rides.
2. Boca Raton Fine Art Show, presented by Hot Works, November 7 and 8 at Sanborn Square. Hours are 10 a.m. to 5 p.m. Saturday and 10 a.m. to 4 p.m. Sunday, and admission is free.
3. Red, White & Boca, the City's Veterans Day event, Wednesday, November 11, 4 to 7 p.m., at Mizner Park Amphitheater, 590 Plaza Real. It includes a veterans marketplace, a classic-car show, and live music.

FDOT has not published a detour or construction parking plan for these dates. Its weekly report names no alternate route. The City's usual parking options still apply. For Sanborn Square, the City lists street parking and a public lot at NE 2nd Street and NE 1st Avenue. The Brightline Boca Raton station at 101 NW 4th Street is within walking distance of downtown, and parking can be added when booking a ticket.

The Mizner Park event also connects to the project directly. The new signalized mid-block crosswalk, with added lighting, is planned just south of Plaza Real. When it is finished, it will give people on foot a signal-controlled crossing at Mizner Park's front door instead of a walk to the nearest intersection.

How a 2018 Study Became a 2026 Work Zone

This change has been planned for almost a decade:

1. May 17, 2018. The Palm Beach TPA Governing Board adopted the US-1 Multimodal Corridor Study. The study also recorded the City's preference for a one-way-pair alternative through downtown.
2. September 2024. FDOT presented the plan at a City Council work session, Boca Daily News reported.
3. June 4, 2025. At FDOT's public meeting, a handful of residents came in person and ten watched remotely. The Boca Raton Tribune reported that attendees offered support and suggestions and raised no objections. WPTV reported that FDOT based its proposal on the corridor study and on 2040 traffic-demand and safety analysis.
4. August 20, 2026. Construction began under contract T4740. General Asphalt Company, LLC is the contractor, and the estimated construction cost is $6.3 million. FDOT's project flyer says the project was developed in coordination with the City and at its request.
5. Late 2027. This is the completion estimate in FDOT's October 2, 2026 traffic report. The project page still lists July 2027, but the weekly report is the more recent document.

Lane closures change week to week as work moves along the corridor. The northbound one-lane reduction is scheduled only through October 16. FDOT posts closures and pedestrian impacts in its weekly Palm Beach County construction reports, and those reports are the best way to check before a downtown trip.

A street rebuild like this one changes how a block works day to day, from where people cross to how they ride and park. Those changes matter when you buy or sell a home nearby.
