Q Who won the $100 Clipper card for picking the opening date for the BART Warm Springs station on Saturday, March 25? I know it wasn’t me but I was close (March 28).

Philip Castillo

A No one picked this Saturday as the day when trains would begin carrying passengers. So by the powers invested in me by me, I selected two winners whose guesses were just a day off. More than 3,000 people entered the Roadshow contest, and they were the only ones so close to the correct date.

— Joanna Chang, a retiree from San Ramon, who picked March 24.

— Jon Baur, a smog technician from Hayward, who picked March 26.

Baur rides BART to San Francisco for the free museum days: “This card will come in quite handy,” he said.

Roadshow: I-580’s potholed Altamont Pass is repaved Members of the public wishing to attend Friday’s pre-opening celebration can drive to the Warm Springs station, 45193 Warm Springs Blvd., and park for free. The event runs from 10 a.m. to noon, rain or shine, and will include speeches, ribbon cutting, station tours, entertainment and a new three-car train for public viewing. (There will also be a free shuttle for attendees from the Fremont BART Station’s west side, near the clock tower, from 8:45 a.m. to 1 p.m.)

Q Folks who live near the east hills of San Jose don’t want a freeway cut through the Hamilton Range to Interstate 5 and Patterson. The noise, air pollution and increased traffic would render entire neighborhoods unlivable. Those who insist on driving everywhere are just going to have to accept heavy traffic and long drives. Such is life in our overcrowded state.

A Yes, it certainly is.

Q My husband and I took a trip to Fairfield recently and I couldn’t believe the litter on Interstate 80. Next to the commuter lane there was a barbecue grill, an ice chest and so many Caltrans orange cones I lost count, plus all kinds of small garbage and paper.

I couldn’t believe Caltrans hadn’t picked up any of the garbage; you could tell it had been there for a while. If someone was to hit even an orange cone it would tear up their car! And if they hit a barbecue … well, I can’t even imagine!

A Help is coming soon. Caltrans has not been idle: Last week crews cleaned I-580 from the Lakeshore exit to the San Pablo exit, I-880 from Hegenberger Road to High Street, the Caledcott Tunnel bores, the Posey and Webster tubes, Devil’s Slide and toll plazas at the Bay Bridge, the Richmond Bridge, the San Mateo Bridge, plus the Rio Vista Delta Bridge.

Q There is always a lot of water on the road at the entrance to the Caldecott Tunnel Bore 1 and for about 50 or more feet. What causes this even when there is no rain?

A This is a year-round, natural water flow that comes down from the hills above the tunnel.
