The San Francisco 49ers are moving to Santa Clara next season. But a popular East Contra Costa shuttle service to the team's home games is not.

Tri Delta Transit's board of directors unanimously punted this week on the idea of continuing its service on game days to Levi's Stadium next September.

"At this point, I think the best thing to do is wait and see how it plays out," said county Supervisor Federal Glover of Pittsburg, the board's chairman.

The service to Candlestick Park, which started in 2002, averages about 175 riders.

Tri Delta board members said there are numerous red flags in the planned setup for bus parking at the $1.3 billion Santa Clara facility. For instance, the parking lot off Democracy Way is about a half-mile from the stadium, Tri Delta Executive Director Jeanne Krieg said.

Candlestick Park's bus lot is just outside the stadium, said Glover, an avid 49ers fan who takes the shuttle to games.

"There's a convenience for riders because it puts you right there. You're close enough you can join people who are tailgating," he said.

Also at issue is the cost to park at the game. Buses pay $40 to park at Candlestick Park, and the drivers are allowed into the stadium, Krieg said. Though there is no official word on how much parking will cost at Levi's Stadium, Krieg said preliminary talks indicate that it could exceed $100. And the driver would not be allowed in.

Though the new stadium's parking arrangements are still in flux, Krieg said the proposed charter bus and RV area could accommodate only about 100 buses and RVs.

Other options, such as connecting to other bus lines, did not make sense, the board said.

"I think that they will figure it out. I just don't want to be part of the figuring-it-out process," Krieg said.

Adds Glover: "Maybe something will come up that will be a good fit for us."

East Contra Costa football fans will still be able to head to Candlestick on the shuttle through the end of this year. Pickups are still at the Brentwood Park-And-Ride off Walnut Boulevard, Antioch Park-And-Ride off Hillcrest Avenue and Pittsburg Park-And-Ride off Bliss Avenue.
