Bow Channel Bridge

Overview

At roughly mile marker 20 between Upper Sugarloaf Key and Park Key, the Bow Channel Fishing Bridge is a retired span reborn for low‑key Keys pleasures: casting a line, strolling above shallow turquoise water, and soaking up big‑sky views. It sits alongside the active US‑1 bridge and forms part of the Florida Keys Overseas Heritage Trail.

What You'll See

Expect sweeping views over calm backcountry flats—prime habitat near Great White Heron National Wildlife Refuge. It’s a classic Keys scene: teal channels, mangrove islets, and long horizons that photograph well from the bridge railings.

Why It Matters

Many old Overseas Highway and railroad spans were repurposed after the 1935 hurricane; this is one of those legacy pieces now serving walkers, cyclists, and shore‑bound anglers. It’s simple, authentic, and very Keys.

Logistics

Access is straightforward: pull off on the gravel shoulder by the bridge, and you’re on it. There’s no fee and it’s open around the clock. Amenities are nil—no restrooms, freshwater, bait, or picnic tables—so come self‑sufficient and pack out everything you bring. If you see “No fishing from bridge” signs, those apply to the active highway span; use the adjacent fishing bridge.

Wildlife

Scan for great white herons and other wading birds working the flats; dolphins and manatees sometimes cruise the channel. Key deer roam the nearby islands—your best odds are dawn and dusk around Big Pine and No Name—so drive slowly and never feed wildlife.

Angling Notes

Bridge pilings hold structure‑loving species like mangrove snapper and jacks. Many locals favor braid with mono or fluoro leaders and carry a bridge net to land fish cleanly. Monofilament recycling tubes are on site—use them. Make sure you have a valid Florida saltwater license and know current size/bag limits.

Best Time to Visit

• For views and a breezy walk: early morning or late afternoon for softer light and cooler temps.
• For fishing: focus on tide changes, and don’t overlook nighttime when action often improves.
• Weekends see more passersby on the trail; weekdays are typically quieter.
