The riverfront below the Jupiter Inlet Lighthouse has been a construction zone for most of two years. That ends soon. The Bureau of Land Management has set December 3 for the grand opening of the $16 million shoreline project around the red tower, and what residents will walk onto that day is a different place: a boardwalk on the Loxahatchee River, a rebuilt beach, a terraced waterfront with nine sets of stairs to the water, and a reef you can snorkel.

Why the lighthouse needed a new edge

The lighthouse sits on a 120-acre federal preserve, the Jupiter Inlet Lighthouse Outstanding Natural Area, set aside by Congress in 2008. It is the only piece of the National Conservation Lands system east of the Mississippi, which surprises most people who have driven past it for years.

The problem was the water. According to the BLM, the site was losing roughly seven feet of shoreline every year. Bluffs were collapsing, trees were tumbling into the Intracoastal, and the sand washing off the property was adding to the dredging bill for the waterway. Left alone, that erosion was on course to threaten the 1860 tower itself.

Crews broke ground in March 2025. The money came from two places: $8.3 million from the federal Great American Outdoors Act and $7 million from the Florida Inland Navigation District, with about $0.7 million more from other sources, per the project page.

What got built while the fences were up

The engineering is mostly invisible now, which is the point. More than 200 helical anchors hold a steel sheet pile wall in place, and above it sits a second wall of stacked gravity blocks. Together they form a two-tier, curved terrace along about 800 feet of shoreline. Out in the water, a chain of limestone breakwaters (22 in all, according to a BLM update this spring) knocks down boat wakes and waves before they reach the bank.

Then came the part people will actually use. The project log shows barges delivering sand in early June to rebuild the beach in front of the wall, and crews finishing traditional chickee huts the same month. Over the summer an accessible pathway leading to the boardwalk and a new native plant trail neared completion, and the north end of the boardwalk moved into its final stretch in late August.

The BLM describes the finished boardwalk as roughly 700 to 800 feet long, running along the Loxahatchee River side of the property. A new dock is planned for ferries and water taxis, which raises the prospect of arriving at the lighthouse by boat rather than by car.

A reef, a turtle study and thousands of mangroves

The most unexpected piece went in last month. On September 9, the first experimental reef arch structure was set on the river side of the property, the start of an artificial reef system meant both for research and for visitors in masks and fins. The day after, researchers placed acoustic monitors in the water to follow green sea turtles and other species moving through the inlet.

The planting has been just as hands-on. The overall plan calls for 10,000 new mangroves and a two-acre salt marsh. In a single Memorial Day workday this year, BLM staff, interns and local volunteers put in 147 native plants and 135 mangroves, well past their target, according to the agency's own account. Volunteer plantings with the MANG Foundation followed in July and August. Even the old vegetation was saved: about 200 plants were dug up before construction and cared for at The Nature Conservancy's Blowing Rocks Preserve to be returned once the work wrapped.

What is left before December

The BLM's look-ahead for September through November lists the last breakwater and boardwalk work, more volunteer planting days, a conservation crew mulching the new trail system, and installation of a floating dock. After the December 3 celebration, the agency says the public will be invited onto new beaches, additional miles of trail and snorkeling routes around the reef structures.

One practical note if you are planning a visit sooner: the lighthouse and museum are closed for maintenance through Tuesday, October 13. Climbs resume after that, Tuesday through Sunday from 10 a.m. to 4 p.m., at 500 Captain Armour's Way. Adult admission is $15, and children 5 and under get in free.

What it means if you live here

For most of Jupiter and Tequesta, the lighthouse has been something you look at: from the Jupiter Inlet, from the bridge, from a boat on a Sunday. The shoreline project quietly turns the ground beneath it into a waterfront park. A boardwalk on the river, a beach, stairs down to the water, a reef worth snorkeling and a dock that could bring water taxis to the door add up to a reason to spend an afternoon there instead of a quick climb and a photo.

It also means the landmark that defines northern Palm Beach County is no longer slowly sliding into the Intracoastal. A tower that has stood since 1860 now has a waterfront built to hold, and come December, everyone gets to walk it.
