Clipper Connection Information

About the Clipper Connection

The Clipper Connection is COAST's express bus service to the Portsmouth Naval Shipyard and the businesses of Pease Tradeport.  

The project is funded in part with support from the US Navy's facilities division (NAVFAC) as well as a USDOT Congestion-Mitigation/Air Quality (CMAQ) grant.  The routes currently operating are just the beginning of what is expected to be a larger, multi-route service covering much of southeastern New Hampshire and border communities in southern Maine.

The service is open to the public, but serves primarily employees of the Navy Yard or Pease Tradeport.

How It Works

  • All COAST bus routes are open to the public.
  • Buses will fill on a first-come, first-served basis.
  • The buses seat 37-39 people, with room for standees up to a total of nearly 80 passengers. We’ve factored in these limits into our route design to minimize the potential that anyone would need to stand for much more than 10 minutes.
  • Our ADA-compliant buses are able to transport two passengers using wheelchairs or other mobility devices.
  • Each bus can carry 2-3 bikes on the front bicycle rack on a first-come, first-served basis. Please be prepared to lock your bicycle at your pickup-point if the rack is already full.
  • Schedules are approximate. Be at your stop about 5 minutes before the published time to ensure you don’t miss the bus. The morning bus will not depart any time point early. The afternoon return bus will not depart pickup locations early, but all stops after a certain point become drop-off only, and may not run according to schedule. Please refer to the schedule pamphlet for details.

Service Issues

  • COAST is the main contact if you have questions, complaints, or suggestions about our service – please do not contact staff at PNSY with these issues. If you need to contact us, you can reach us by phone at 603-743-5777.
    • Questions about the schedule, if the bus is late, stop locations, etc. go to Dispatch. Press 1.
    • Complaints (and commendations!) about the service go to our Supervisors Desk. Press 4.
    • Suggestions, planning, and service requests go to our Manager, preferably emailed to coast.nh@gmail.com, subj. “Clipper Connection”
  • COAST will operate service in just about any weather. In the 2008 ice storm, COAST buses continued to run without incident, despite no power to our radio tower or dispatch center. In the unlikely event of a major service interruption, notice will be posted through as many of the following means as possible:
    • All local radio stations
    • New Hampshire’s WMUR and Portland’s WCSH
    • Our Twitter feed features regular updating for service conditions. @COASTbus (www.twitter.com/COASTbus)
    • Our website will be updated for planned service outages
    • Our phone system greeting will always be updated during bad weather with up-to-the-minute status of bus departures.
  • COAST observes six holidays on which no service is operated. Those are New Year’s, Memorial, Independence, Labor, Thanksgiving, and Christmas Day.
