Why are we proposing these changes?

  • Truncating Route 522 at Roosevelt Station provides consistent service levels from North King County by leveraging the new Northgate Link extension and conserving resources.
  • During peak periods, additional capacity will be provided in the SR-522 corridor by the proposed King County Metro Route 309 and 322.
  • Route 309 and 322 will also connect with Link at Northgate and Roosevelt stations while also providing access to destinations near downtown Seattle less well-served by light rail.
  • Timing of trips on among the three routes will be coordinated to provide consistent spacing of buses.

What does this mean for riders?

Benefits

  • Truncating Route 522 at Northgate would allow riders to access new destinations served by Link and avoid congestion on part of I-5.
  • In September 2021, midday, evening and weekend service would increase to every 15 minutes.

Trade-offs

2021 SIP Route 522 Roosevelt map Inset
  • Riders would need to transfer in order to reach downtown Seattle, which could increase travel times by an estimated 2-10 minutes in off-peak times. The transfer requires walking 1-2 blocks as shown in the map.
  • Rush hour frequency would be reduced in order to provide higher midday, evening, and weekend frequency. King County Metro will continue to provide parallel service on the corridor, supplementing Route 522 during rush hour.
