Mayport Road is about to go on a road diet. Atlantic Beach and the Florida Department of Transportation plan to shrink the six-lane stretch between Atlantic Boulevard and Dutton Island Road to four lanes, while carving out more room for people on foot and on bikes. The city calls it a $9.6 million multi-modal improvement project, set to kick off June 15, 2026, with milling, resurfacing and lane repurposing on the menu. Drivers, cyclists and businesses along the corridor should brace for months of mostly overnight work as crews restripe lanes, upgrade signals and build a shared-use path.
What The Road Diet Includes
According to the City of Atlantic Beach, the plan will convert the current three-lanes-each-way setup into two lanes in each direction. The space that is freed up will be reallocated for a 12-foot shared-use path, a dedicated southbound bike lane and wider sidewalks on the northbound side, along with signalized intersection upgrades.
The city notes that J.B. Coxwell Contracting has been awarded the construction contract. In addition to new striping and reconfigured lanes, crews will handle curb, drainage and pavement repairs along the corridor.
FDOT Cost Estimate And Design Details
FDOT materials describe the same basic safety and multi-modal features, including milling and resurfacing, lane repurposing, signal upgrades and a southbound bike lane. An earlier estimate from FDOT put the project value near $11.6 million and showed planning-era timing that differed from the more recent schedule the city is using. The handout also lays out the technical cross sections and design details for those who want to dive into the fine print.
Night Work, Lane Shifts And Slower Speeds
The city has posted that construction will begin June 15, 2026 and that most work will take place at night, Sunday through Thursday, to keep daytime disruption in check. No lane closures will be allowed between 6:00 a.m. and 8:00 p.m., according to the City of Atlantic Beach on Facebook.
Even with that restriction, motorists should plan for shifting lanes, temporary reduced speed limits and occasional overnight detours while crews mill and pave the roadway and install the new bike and pedestrian facilities.
What Neighbors And Business Owners Are Hearing
FDOT held public meetings during the design phase so nearby residents and business owners could weigh in on access, parking and the lane changes. As reported by Action News Jax, the sessions took place at Atlantic Beach City Hall and online and included project displays and question-and-answer time with staff.
Officials say the end goal is to calm traffic speeds, cut down on crashes and make Mayport Road safer for the growing mix of commuters, servicemembers and beachgoers who rely on the corridor.
