What You'll Find at Atlantic Beach Causeway

The Atlantic Beach Causeway is a 2.2-mile bridge connecting Morehead City to Atlantic Beach, North Carolina, and it holds fish year-round because it spans Bogue Sound—a shallow estuary where water temperature and structure create predictable feeding patterns. The causeway itself is not open to foot traffic, but the waters around its pilings hold red drum, spotted seatrout, flounder, and Spanish mackerel depending on season. The real value for anglers is the access points at both ends: the Morehead City waterfront on the west side and the Atlantic Beach side on the east, each offering different depths, current, and species.

Most anglers fish the sound from boats or wade the shallows near the causeway's approach roads rather than attempting the bridge itself. The structure—pilings, riprap, and the channel it creates—concentrates baitfish and predators, making it worth the short run from either end. Water clarity varies with tide and recent rain, but the sound is generally fishable even when coastal waters are rough.

Key Takeaways

  • The causeway's pilings and riprap hold red drum and spotted seatrout year-round, with peak activity in spring and fall when water temperatures favor feeding.
  • Boat access is available from Morehead City's public ramps and from Atlantic Beach; wading is possible in shallow flats near the causeway approaches during lower tides.
  • Spanish mackerel and flounder move through the sound seasonally, with mackerel most common May through September and flounder best in fall and early spring.
  • The causeway creates a current break and channel that concentrates baitfish, especially mullet and menhaden, which draw larger predators to the structure.

Boat Access and Launch Points

Morehead City has two public boat ramps: the Morehead City Port Authority ramp on Evans Street (near the commercial docks) and the Grayden Paul Causeway Park ramp, which sits directly on the sound side of the causeway approach. The Evans Street ramp is deeper and better for larger boats; Grayden Paul is shallower and closer to the causeway structure itself. Both charge a small daily launch fee, and parking is available at each site.

From the Atlantic Beach side, you can launch at the Atlantic Beach Causeway Park ramp, which is smaller but puts you immediately in the sound. The run from either ramp to the causeway pilings is less than five minutes, making it practical for a half-day trip. Tides matter here—the sound drains significantly at low tide, and some of the shallower flats near the causeway become impassable in a deep-draft boat.

Seasonal Patterns and Target Species

Spring (March through May) brings spotted seatrout and red drum to the causeway structure as water temperatures climb into the 60s. Trout move shallow to feed on mullet and shrimp; drum follow the same baitfish but often hold deeper near the channel. Live mullet under a popping cork works well for trout; heavier jigs and live baitfish work better for drum. Water clarity is often poor in spring due to runoff, but the causeway's structure concentrates fish regardless.

Summer (June through August) is slower for most species—heat pushes trout deeper into channels and drum move to the ocean side of the barrier islands. Spanish mackerel, however, move into the sound and feed aggressively around the causeway pilings, especially on incoming tides. Small silver spoons and live shrimp work well. Early morning and late afternoon are most productive.

Fall (September through November) is the strongest season. Spotted seatrout return to shallow structure, red drum stage in the sound before moving offshore, and flounder move through on their way to deeper winter grounds. The causeway pilings hold all three species simultaneously. Water temperatures drop into the 60s and 50s, and fish feed heavily. Live mullet, live shrimp, and small jigs all produce.

Winter (December through February) is slow but not dead. Red drum hold in the deepest parts of the sound and near the causeway channel; they are catchable but less aggressive. Spotted seatrout scatter into deeper holes. Most anglers shift effort to other Morehead-area spots during winter, but the causeway can still produce on mild days with live baitfish.

Wading and Shore Access

Wading is possible in the shallows near both causeway approaches, especially on lower tides when flats that are normally 3 to 4 feet deep drop to 1 to 2 feet. The bottom is soft mud and sand—good for wading but slow going. Spotted seatrout and red drum hunt these flats, particularly in spring and fall. Wade early in the morning before boat traffic stirs up the water.

Grayden Paul Causeway Park on the Morehead side has a small pier and shoreline access where you can cast toward the pilings without a boat. The pier is short and often crowded, but it works for spotted seatrout and small red drum, especially on incoming tides. Atlantic Beach Causeway Park has similar shoreline access on the east side. Both parks have parking and restrooms, making them practical for a quick morning session.

Tides, Current, and Timing

The causeway creates a current break—water flows around the pilings and structure, concentrating baitfish and predators on both the incoming and outgoing tides. Incoming tide (flood) is generally more productive because it pushes baitfish toward the structure and triggers feeding. The hour before and the hour after slack tide (the transition between incoming and outgoing) can be slow, but the two hours of strong incoming tide are usually excellent.

Tidal range in Bogue Sound is modest—typically 2 to 3 feet—but it matters for wading access and for where fish hold. At high tide, fish spread into the shallows; at low tide, they concentrate in the channel and deeper water near the causeway. Plan your tide around your target species: trout and drum feed more actively on rising water, while flounder hunt the flats as tide comes in.

Tackle and Bait Recommendations

Live mullet (4 to 6 inches) is the most reliable bait for red drum and larger spotted seatrout. Fish it under a popping cork in 2 to 4 feet of water near the pilings, or on a simple slip sinker rig in the channel. Live shrimp works for trout and flounder but is less effective for drum. You can catch mullet in the sound itself using a cast net, or buy them from bait shops in Morehead City.

For artificial lures, small silver spoons (1/4 to 1/2 ounce) work well for mackerel and trout. Soft plastics rigged on 1/8 to 1/4 ounce jigs produce for trout and flounder in the shallows. Topwater plugs can draw strikes from trout and drum early in the morning, especially in spring and fall. Bring a mix—the causeway holds multiple species, and what works one day may not work the next.

Frequently Asked Questions

Can you fish from the causeway bridge itself?

No, the causeway is closed to pedestrian traffic and fishing. You must fish from a boat or from the shoreline and pier access at Grayden Paul Causeway Park (Morehead side) or Atlantic Beach Causeway Park (Atlantic Beach side).

What's the best time of day to fish the causeway?

Early morning (sunrise to 9 a.m.) and late afternoon (3 p.m. to sunset) are most productive, especially in summer when midday heat slows feeding. In spring and fall, the entire incoming tide can be good. Avoid midday slack tide, when current stops and fish feed less actively.

Do I need a boat to fish the causeway?

No. The shoreline at both causeway parks offers casting access to the structure, and wading is possible in the shallows near the approaches on lower tides. A boat lets you reach deeper water and the channel, but it is not required for success.

What's the water depth around the causeway pilings?

Water depth ranges from 2 to 3 feet in the shallows near the approaches to 8 to 12 feet in the channel under the causeway itself. Depth varies with tide—low tide exposes more shallow water, while high tide covers the flats.

Is there a fee to launch a boat at the causeway ramps?

Yes, both Morehead City and Atlantic Beach ramps charge a daily launch fee. The amount varies but is typically $5 to $10 per day. Grayden Paul Causeway Park and Atlantic Beach Causeway Park also charge for parking if you use the shoreline access.
