"That's the question we keep getting from people, is how am I supposed to use this?" Mayor Dave Rosenbaum told KOMO News in early April, a week after light rail reached the island.
Six months later, the 2 Line's schedule has settled. The tricky part of using Mercer Island Station is the half mile or more between your front door and the platform, not the ride itself. Two different timetables decide that stretch, and after early evening they stop lining up. From then on, getting between home and the station depends on the available connection: a walking or biking route, a drop-off, or a legal place to park.
Two timetables, five hours apart
According to the City of Mercer Island, the station has been open since March 28, 2026. It runs Monday through Saturday from 5 a.m. to 1 a.m., and Sunday from 6 a.m. to midnight. The buses that bring riders from elsewhere on the island keep much shorter hours. Here is the current picture, based on King County Metro timetables in effect from August 29, 2026, through March 26, 2027:
| Service | Days at Mercer Island | Span of island service |
|---|---|---|
| 2 Line light rail | Daily | 5 a.m. to 1 a.m., Mon to Sat; 6 a.m. to midnight Sun |
| DART Route 204 | Weekdays and weekends | Weekday fixed route into early evening; hourly weekend loops from 9 a.m. to around 6 p.m. |
| DART Route 630 | Weekdays only | 6 to 8:15 a.m. and 4:45 to 7:15 p.m. |
| Route 215 | Daily | Half-hourly trips; last listed station trips shortly before 8 p.m. |
| Route 218 | Weekdays only | Morning trips arrive at the station from 5:49 to 9:17 a.m. |
| Route 269 | Daily | Last listed station departure at 7:30 p.m. |
Most of those routes are recent. Metro's August 29 service change added Route 215, which links Mercer Island with Eastgate, Issaquah Highlands, Snoqualmie and North Bend. It also cut Route 218 back to start and end at Mercer Island Station instead of Downtown Seattle, and extended Route 269 to the island from Issaquah Highlands. Route 269 now runs on weekends, and every 15 minutes during weekday peaks.
Most of those additions carry people from Issaquah and points east to the train. The two routes that actually loop through island neighborhoods, the 204 and the 630, are DART services that can leave their fixed route to pick up or drop off riders within a set area. To book one of those detours, you call 1-866-261-3278 at least two hours ahead. On the 204, the detours run weekdays from 9 a.m. to 3 p.m. and Saturdays from 9 a.m. to 7 p.m.
Back in April, KOMO reported that the 204 and 630 stop before 7 p.m. on weekdays even though trains run until midnight, and that Metro had no plans to expand island service. The August timetables did not change that pattern for the island loops. Sunday is the thinnest day of all, with no 630 and no 218.
Where the car goes at night
For most trips after dark, that leaves the car, and the evening rules differ from the daytime ones.
The Park-and-Ride. The two-level garage at 8000 N Mercer Way is owned and run by Sound Transit. It has 447 stalls plus 10 ADA spaces, all free to transit riders on a first-come, first-served basis. Vehicles parked longer than 24 hours can be ticketed or towed. Sound Transit says its parking facilities are open to passengers 24 hours a day. In 2019, Sound Transit announced a reserved permit option for weekday-morning spaces here. That no longer applies. Mercer Island is not on Sound Transit's current permit list, and Metro has suspended its own permit program. The real constraint is commuter demand. Per KOMO's April report, the garage fills "quickly and early in the day." No public occupancy counts have been released for 2026, so it is not known how many spaces open up once weekday commuters drive home.
The Town Center Parking Area. This 33-stall lot at 7810 SE 27th St., just south of the transit center, is the city's own. You register through ParkMobile. The first two hours are free, then it costs $2.50 an hour up to a $12.50 daily maximum, with a 14-hour limit. Those rules apply from 8 a.m. to 10 p.m. every day. An evening trip that starts at 6 p.m. stays inside the free window until 8 p.m. The enforcement window closes at 10 p.m. KOMO described this as 36 paid spaces, but the city's own page lists 33.
The street. The city's 2025 parking plan posts Town Center curbs at two hours from 8 a.m. to 10 p.m., Monday through Saturday. You have to move to another block to park again, and no later change to those rules was found. North of the station, the North Mercer Restricted Parking District issues permits to eligible residents and their guests. KOMO reported that most streets around the station require permits from 8 a.m. to 5 p.m. on weekdays. The city's own guidance is to check posted signs, which beats any summary.
The island has already tested a different approach once. On World Cup match days in June and July, the city offered island residents free parking at the Mercer Island Community and Event Center lot and charged non-residents. As the Mercer Island Reporter reported, fees from that lot and the Town Center Parking Area totaled $17,590, money set aside for police overtime during the games. That was an event-day plan, not standing policy. Still, it shows the city can open a resident-priority lot near the station when demand spikes.
The bike room is the cheapest seat in Town Center
The station has 32 spaces in a secure bike room and 50 rack spaces. There are 24 BikeLink lockers at the Park-and-Ride and 8 more at the Town Center Parking Area. The lockers and the secure room are first-come, first-served, open 24 hours a day, and cost $0.05 an hour with a BikeLink card or app. Four hours in the bike room costs 20 cents, compared with $5 for the same four hours in the Town Center lot once the free window runs out.
Bikes have no service hours, so they fill the evening gap the buses leave. Riders come in through one of two entrances, on 77th Ave SE or 80th Ave SE, which matters when you're deciding which side of the freeway lid to lock up on. The city also publishes a bicycle routes map for planning a route from the south end.
Running the numbers on a night across the lake
The trip home is the leg that needs planning. Here is how a weeknight works on Sound Transit's 2 Line timetable for Monday, October 12, 2026:
- Getting there is quick. The scheduled ride is about 10 minutes from International District/Chinatown to Mercer Island and about 15 minutes from Westlake. Heading east, Bellevue Downtown is about 12 minutes from the island. These are station-to-station times that leave out the walk and the wait.
- Trains run every 8 minutes during the evening rush and roughly every 10 minutes after 8 p.m. Through the last full hour of evening service, island-bound trains reach Mercer Island at 10:26, 10:38, 10:50 and 11:02 p.m.
- After 11 p.m. the gap grows to 16 minutes. Arrivals at Mercer Island come at 11:18, 11:34 and 11:50 p.m., then 12:06, 12:22 and 12:38 a.m.
- The last island-bound train on that schedule leaves Westlake at 12:23 a.m. and reaches Mercer Island at 12:38 a.m.
- The ride from the station to your door is the same at 10:30 p.m. as at 12:38 a.m. By then no island bus is running, so it depends on the bike room, a ride or the car you parked earlier.
Put next to the bus table, those figures show how wide the gap is. On a weeknight, the 2 Line keeps running for roughly five hours after the last listed station departures on Routes 269 and 215, both before 8 p.m. For arena or stadium nights, symphony evenings and late dinners downtown, those five hours are what the station offers. Using them takes some planning before you leave the island.
What the island is still working out
Usage figures so far fit a station that is easier to reach on foot than by bus. Seattle Transit Blog reported that in April 2026, Mercer Island averaged 1,723 weekday boardings, compared with 2,130 at Judkins Park, the other new station on the cross-lake segment. The same analysis put Eastside 2 Line ridership up 505% from April 2025, which was before the cross-lake connection opened.
For Town Center businesses, early signs have been encouraging but hard to read. KOMO reported that Hap's Burgers and Taps did about 50% more business on opening day than on a typical day. The owner noted that good weather may have helped, and other owners were unsure the bump would last. The mayor has said the city wants commuters out of the short-term Town Center spaces. "We need these spots to turn over so we have opportunity for customers to come in," he told KOMO. That goal ties back to the Town Center parking rules the City Council adopted on May 6, 2025, which include the two free hours at the city lot. When the lot opened that July, the City Manager told the Mercer Island Reporter it was meant to support transit access while keeping turnover for businesses. For the restaurants covered in our August evening guide, and for whatever eventually fills the storefronts in the new Town Center building, that turnover matters.
In April, the mayor said the city was looking at shuttles, shared rides and public-private partnerships to add parking. As of this month, the city's Getting Around guide lists the 2 Line and the DART routes, with their bookable daytime detours, but no separate city-run shuttle or evening on-demand program. No council action on station parking since April turned up in our research. Until something changes, the evening options are the garage, the 33-stall lot, the bike room or a ride from someone at home.
Station access has become one of the first things clients ask about when they compare streets on the island, and the answer varies a lot from the north end to the south end.
