Sebastian Inlet Bridge

The Sebastian Inlet Bridge, named for state legislator James Pruitt, is the 1,548-foot span that carries State Road A1A across Sebastian Inlet on the Indian River and Brevard county line, east of Sebastian (FDOT).

FDOT lists it as bridge No. 880005 in the National Bridge Inventory, built in 1964 and sitting beside Sebastian Inlet State Park inside the Sebastian Inlet District right of way (FDOT PD&E study). The road it carries is signed as the Jimmy Buffett Memorial Highway (Florida State Parks), and the bridge is part of the 233-mile Indian River Lagoon National Scenic Byway, designated June 13, 2000.

The crossing serves Sebastian Inlet State Park on both banks. Campgrounds and a boat ramp sit at the southern entrance, fishing happens at the north entrance, and a swimming cove lies northwest of the bridge. FDOT recommended the 1964 bridge as eligible for the National Register of Historic Places under Criterion C, engineering, as a high-integrity example of prestressed concrete (FDOT).

The Sebastian Inlet Bridge was built by Cleary Brothers Construction Company of West Palm Beach, completed in 1964 and dedicated before an estimated 8,000 people on February 27, 1965 (Sebastian Inlet District).

State Representative James H. Pruitt pushed the project through. He introduced a bill moving the Brevard and Indian River county line north to the center of Sebastian Inlet, which put the south half of the bridge in Indian River County and brought that county's road money into play (District history of the span). At noon on dedication day Pruitt cut a red, white and blue ribbon held by high school students from both counties, while Air Force jets made three low passes.

The land deal shows on today's maps. The District's inlet history records that, in return for help completing the bridge and paving A1A on the south side, Brevard County ceded almost 3 miles of land south of the inlet to Indian River County (Sebastian Inlet District).

The name came later. The Legislature first dedicated the bridge to Robert W. Graves in 1965, and in 2004 it was rededicated to Pruitt, who had served as a council member and mayor of Eau Gallie in the 1950s and in the Florida Legislature from 1959 to 1967 and who died in 2002 (Sebastian Inlet District). The rededication ceremony took place at Sebastian Inlet State Park on November 18, 2004.

The 1964 Sebastian Inlet Bridge is 1,548 feet long with a 180-foot main span, a 120-foot horizontal clearance and a deck 34 feet 3 inches wide (FDOT).

Catwalks run beneath the Sebastian Inlet Bridge deck and the jetties extend along the inlet to the Atlantic, according to the District's fact list, which also gives the 37-foot vertical clearance (District fast facts). The District's own navigation page lists 39 feet (Navigation), so the two official figures for the existing bridge differ by 2 feet; FDOT's study uses 37.

FDOT is replacing the Sebastian Inlet Bridge because a November 14, 2018 inspection rated it structurally deficient, with a sufficiency rating of 51.6 and a health index of 79.8 (FDOT).

FDOT District Four ran the Sebastian Inlet evaluation after Hurricane Florence. Its bridge policy says structurally deficient bridges should be replaced within six years, and bridges with a health index under 85 need repair or replacement. The study describes the span as in poor condition, structurally deficient, functionally obsolete and scour critical (FDOT PD&E study).

The project also fills gaps the 1964 design left on A1A at Sebastian Inlet, where FDOT identifies a gap in the bicycle and pedestrian network. FDOT states its purpose as fixing the structural and functional deficiencies, closing the gap for bicyclists and pedestrians, improving drainage and raising the vertical clearance for resiliency. FDOT granted Location and Design Concept Acceptance on May 23, 2023, and the project was let for construction on December 3, 2025 (FDOT project page).

The two FDOT project pages give slightly different prices for the Sebastian Inlet bridge. The department's project page lists an estimated construction cost of $102 million (FDOT), while the FDOT District 4 construction page, which names Webber, LLC as contractor, lists $101.9 million (FDOT District 4).

The new Sebastian Inlet Bridge will sit just east of the old one, carrying two 12-foot travel lanes, two 8-foot shoulders and two 12-foot shared use paths, with fishing walks below on both shores (FDOT).

FDOT District 4 lists the new fixed bridge at 51 feet of vertical clearance, 14 feet more than the 37 feet FDOT gives for the 1964 span, and describes two observation decks, one under the bridge from the south shore and one from the north shore (FDOT District 4). The project runs 1.1 miles along A1A from south of Sebastian Inlet in Indian River County to north of the inlet in Brevard County, and Webber, LLC holds the construction contract.

At the Sebastian Inlet State Park entrances, FDOT plans crosswalks across A1A at the north and south entrances, right-turn lanes out of the park, a southbound acceleration lane from the south entrance and longer southbound right-turn lanes into the park (FDOT project page). The shared use path continues on the west side of the bridge and roadway, and a new one is added on the east side, ending at the park's north entrance. District 4 adds that the park's North and South Parking Lots will be milled and resurfaced (FDOT District 4).

Construction began on June 1, 2026, and A1A stays open across Sebastian Inlet with two-way traffic, while parts of Sebastian Inlet State Park parking are closed through spring 2032 (Town of Melbourne Beach).

FDOT is building in phases to avoid a detour or bridge closure, with two-way traffic maintained at all times and temporary lane closures in non-peak hours (FDOT). The Town of Melbourne Beach's August 17, 2026 update reported single-lane closures, one lane at a time with a flagging operation, for roadway construction and utility relocation (Town of Melbourne Beach).

The road itself is moving in October 2026. The Town of Melbourne Beach's October 6 update set the shift for about 7 a.m. on Tuesday, October 13, 2026, with northbound and southbound A1A traffic moving onto temporary pavement west of the existing road, starting about 1,400 feet south of the Sebastian Inlet State Park entrance in Indian River County, and the shift runs through late 2028 (Melbourne Beach update, October 6, 2026). The date has already moved once, from September 24 in the town's September 15 update, and FDOT District 4's project page now files its traffic shift notice under October 19, 2026, so drivers should check the district page before a trip (FDOT District 4). Sections of the park's North and South Parking Lots are partially closed around the clock through spring 2032 (Town of Melbourne Beach).

Beach and parking access is reduced. The Sebastian Inlet District's posting of FDOT releases records the South Parking Lot as partially closed from June 4, 2026, through spring 2032 (Sebastian Inlet District), and Florida State Parks warns that beach access from the south side is unavailable during construction (Florida State Parks). The District reposts those notices as a courtesy and notes the bridge is not a District project.

The finish date is not settled in the official record. FDOT's project page lists an anticipated construction end of fall 2031 and still describes construction as scheduled to start in spring 2026, months after work began, while the FDOT District 4 construction page gives a June 2026 start and a spring 2032 completion (FDOT; FDOT District 4).
