1. Why Bridge Planning Matters

  • Avoid delays, groundings, and unsafe transits.
  • Save time and stress with verified information.
  • Plan with confidence using current data.

2. Fixed Bridges vs Drawbridges

  • Fixed bridges have set clearances.
  • Drawbridges open on schedules or on request.
  • Verify status and requirements before arrival.

3. Clearance & Air Draft

  • Clearance can change with water levels and conditions.
  • Compare your vessel air draft to current clearances.
  • Closed fields are planning references only.

4. Verify Openings Before Transit

  • Check opening schedules, restrictions, and notices.
  • Confirm with official charts, signage, and local updates.
  • Treat phone/VHF info as starting points, not final.

5. Contact & VHF Planning

  • Note bridge tenders and operator contacts.
  • Use VHF channels for requests and updates.
  • Have backups in case phone service is unavailable.

6. Timing, Water Levels & Restrictions

  • Water levels affect clearance and bridge operation.
  • Consider tides, currents, traffic, and daylight.
  • Watch for maintenance, weather, and local restrictions.

7. Bridge Planning Checklist

  • Compare air draft vs clearance
  • Verify bridge status & type
  • Check water levels & trends
  • Confirm schedules & openings
  • Note contacts & VHF channels
  • Plan timing & backup options

8. Quick Bridge FAQs

  • Can I rely on listed clearances? No, always verify current data.
