The Shands Bridge replacement is a massive infrastructure project involving the construction of a new four-lane, high-level bridge over the St. Johns River, connecting Clay and St. Johns Counties. As part of the First Coast Expressway (State Road 23) expansion, this project replaces the aging 1963 structure to improve regional mobility and accommodate growing traffic demands.
The Shands Bridge, officially a segment of State Road 16, has long served as a vital link between Green Cove Springs and the rural areas of St. Johns County. However, the surge in Northeast Florida’s population and the strategic need for a limited-access outer beltway around Jacksonville necessitated a complete overhaul of this crossing. In 2026, the project is in a critical phase of construction, representing one of the most significant engineering feats currently underway in the Florida Department of Transportation (FDOT) District 2.
The Evolution of the Shands Bridge: From 1963 to 2026
The original Shands Bridge was completed in 1963. For over six decades, it functioned as a two-lane facility with a relatively low vertical clearance of approximately 45 feet. While sufficient for the mid-20th century, the structure became a bottleneck for both maritime and vehicular traffic. The narrow lanes lacked modern safety shoulders, and the aging concrete required increasingly frequent maintenance.
The decision to replace the bridge was not merely a response to the physical condition of the old structure but was driven by the larger vision for the First Coast Expressway (FCE). The FCE is a multi-billion dollar toll road project designed to connect I-10 in Duval County to I-95 in St. Johns County. The Shands Bridge serves as the "Segment 3" anchor for this expressway, transforming a local rural crossing into a high-capacity regional artery.
By 2026, the transformation is visible to anyone traveling State Road 16. The new structure, rising significantly higher than the original, signifies a shift in Florida's approach to infrastructure—moving away from local, surface-level connections toward integrated, high-speed regional networks.
Engineering Specifications and Design of the New Structure
The new bridge is not just a replacement but a total upgrade in scale and technology. Engineering the crossing of the St. Johns River at this location poses unique challenges due to the river's width, the soft silty composition of the riverbed, and the need to maintain environmental protections for local wildlife.
Vertical and Horizontal Clearance
One of the primary drivers for the new design was maritime accessibility. The new bridge features a vertical clearance of 65 feet. This height is the standard for major crossings along the St. Johns River, aligning with the clearance of the Buckman Bridge and the Dames Point Bridge. This allows larger recreational vessels and commercial barges to navigate the river without the restrictions imposed by the old 45-foot height.
The horizontal clearance has also been widened to provide a safer navigation channel for river traffic. By reducing the number of piers in the main channel, the design minimizes the risk of vessel strikes and improves water flow.
Lane Configuration and Multi-modal Access
Unlike the two-lane original, the new bridge carries four travel lanes (two in each direction). Crucially, the design includes:
- Full-width shoulders: Breakdown lanes on both the interior and exterior of the travel lanes to improve safety and prevent traffic jams during accidents.
- Shared-Use Path: A protected 12-foot-wide path for pedestrians and cyclists, offering a scenic crossing that was previously impossible on the narrow 1963 bridge.
- Toll Technology: The bridge is integrated with All-Electronic Tolling (AET), utilizing SunPass and "TOLL-BY-PLATE" systems to maintain traffic flow without physical toll booths.
First Coast Expressway Segment 3 Integration
The Shands Bridge replacement is officially designated as FCE Segment 3, a 15.4-mile stretch that extends from east of County Road 209 in Clay County to I-95 in St. Johns County. The bridge itself is the most complex and expensive component of this segment, with a contract value exceeding $595 million.
The integration into the FCE means the bridge is part of a limited-access highway system. In 2026, work on the interchanges on both sides of the river—specifically the massive interchange at State Road 16 and the future connection to I-95—is progressing in tandem with the bridge deck construction. This project is vital for the evacuation route infrastructure of Northeast Florida, providing a high-capacity path away from the coast during hurricane events.

Construction Timeline and 2026 Milestones
The construction of the new Shands Bridge began in earnest in early 2023, following the contract award to Superior Construction Company Southeast. As of 2026, the project has moved from the heavy foundation phase into the superstructure phase.
Substructure Completion
The foundation work involved driving hundreds of concrete piles deep into the riverbed to reach competent bearing strata. By 2026, the majority of the "bents" (the support structures) and the large main-channel piers are complete. These piers are designed to withstand significant hydraulic forces and potential ship impacts.
Superstructure Progress
Current activity in 2026 focuses on the placement of Florida I-Beams (FIBs)—precast concrete girders that span the distance between the piers. Motorists can now see the "skeleton" of the bridge stretching across the river. The deck pouring process, which uses specialized finishing machines to create a smooth driving surface, is underway on the spans closer to the shorelines.
Projected Completion
While individual sections of the expressway are opening in phases, the full Shands Bridge crossing is expected to be fully operational by 2029 or 2030. The 2026 timeframe represents the peak of construction intensity, with the most significant visual progress occurring as the two sides of the bridge move toward a mid-river closure.
Environmental Stewardship and Wildlife Protection
Constructing a three-mile-long bridge over the St. Johns River requires stringent environmental adherence. The river is a sensitive ecosystem, home to manatees, bald eagles, and various species of fish and shellfish.
Manatee Protection
The St. Johns River is a critical habitat for the Florida Manatee. During construction, FDOT and its contractors employ "Manatee Observers." If a manatee is spotted within a specific radius of pile-driving or dredging activity, all work must cease immediately until the animal moves safely out of the area. In 2026, these protocols remain a daily part of the construction workflow.
Turbidity and Water Quality
To prevent silt and construction debris from damaging the river’s health, turbidity curtains are deployed around all in-water work zones. These barriers ensure that suspended sediments do not spread, protecting the underwater vegetation and fish breeding grounds. Furthermore, the new bridge design includes modern stormwater treatment systems that capture and filter runoff from the road surface before it reaches the river—a significant improvement over the 1963 bridge, which allowed direct runoff.
Economic and Commuter Impact on Clay and St. Johns Counties
The replacement of the Shands Bridge is a catalyst for economic shifts in the surrounding regions. For decades, Green Cove Springs remained a relatively quiet community. With the bridge becoming part of the First Coast Expressway, the area is becoming a prime location for logistics, warehousing, and residential development.
Impact on Real Estate
In 2026, the "FCE Effect" is evident in property values in southern Clay County and western St. Johns County. The improved commute to Jacksonville and the direct link to I-95 make these previously rural areas attractive for large-scale residential communities. Developers are specifically targeting the corridors near the new interchanges created by the Shands Bridge project.
Commuter Logistics
Currently, the old Shands Bridge remains open to traffic during the construction of the new span. However, lane shifts and temporary closures for equipment movement are common. Once the new bridge opens, the travel time between Green Cove Springs and St. Johns County is expected to decrease significantly due to the higher speed limits and the removal of the bottlenecks that occurred on the old two-lane structure.
The Future of the Old Structure: Demolition vs. Repurposing
A common question regarding the "Bridge Shands" project is what will happen to the 1963 structure once the new bridge is completed. Current FDOT plans involve the partial demolition of the old bridge.
However, in a move to support local recreation, parts of the old bridge—specifically the sections closest to the Clay County and St. Johns County shorelines—may be converted into fishing piers. This repurposing has been successful in other parts of Florida (such as the Sunshine Skyway in Tampa). By removing the center spans to allow for the new navigation channel but leaving the ends intact, the state can provide a public amenity while reducing the total cost of demolition and debris removal.
Frequently Asked Questions
Will there be a toll on the new Shands Bridge?
Yes, the new bridge is a component of the First Coast Expressway, which is a tolled facility. Tolling is handled electronically via SunPass or "TOLL-BY-PLATE." There are no physical toll booths; cameras and sensors overhead record transactions at highway speeds.
How much higher is the new bridge compared to the old one?
The new bridge has a vertical clearance of 65 feet above the mean high water line. The old bridge has a clearance of approximately 45 feet. This 20-foot increase is designed to accommodate larger maritime vessels and match the standards of other St. Johns River crossings.
Is the old Shands Bridge currently open during construction?
In 2026, the original Shands Bridge remains open to provide a continuous link for State Road 16 traffic. FDOT has designed the project to ensure that the new bridge is constructed parallel to the old one, minimizing disruptions until the final traffic switchover occurs.
How long is the new Shands Bridge?
The bridge itself spans approximately 3 miles over the St. Johns River and its associated wetlands. When including the approach roads and interchanges that are part of FCE Segment 3, the total project length is over 15 miles.
What are the benefits for cyclists and pedestrians?
Unlike the original bridge, which was notoriously dangerous for anything other than motorized vehicles, the new bridge features a dedicated 12-foot shared-use path. This path is physically separated from vehicular traffic, providing a safe way for pedestrians and cyclists to cross the river.
Final Recommendations for Residents and Travelers
For those living in or traveling through Green Cove Springs and Orangedale in 2026, staying informed is key to navigating the ongoing construction.
- Monitor Traffic Alerts: Use tools like FL511 or the official First Coast Expressway website to check for nightly lane closures or equipment moves that might impact the Shands Bridge crossing.
- Plan for Tolls: If you are a frequent commuter, ensure your SunPass account is active and funded to take advantage of the lowest toll rates once the transition to the new structure begins.
- Boater Awareness: If navigating the St. Johns River, pay close attention to the shifting navigation channels and construction lighting. The work zone is large, and barge movements are frequent.
- Observe Speed Limits: Construction zones on both sides of the river are heavily enforced. Reduced speed limits are in place to protect workers who are often operating just feet away from moving traffic.
The Shands Bridge replacement is more than a construction project; it is the cornerstone of Northeast Florida's future transportation network. By the end of this decade, the legacy 1963 bridge will be a memory, replaced by a modern, high-capacity link that supports the region's economic and social growth.
