Q I commute on Interstate 880 from Fremont to Emeryville. For quite some time there have been areas of construction. What is being built and when will it be ready? I hoped that it might be a carpool lane but there are areas with no construction where there is no room for another lane like the stretch north of 66th Avenue, so that must not be the goal. What is it?

A If it seems like I-880 has been under construction for a couple of decades, it has been and the digging is not done yet. Here's a rundown of current work from Oakland to San Jose.

  • Seismic upgrades at High Street and Fifth Avenue and widening the overpasses. Work will wrap up next year, and this section will then be repaved.
  • Adding concrete center divider from Oak Street to Washington Street in Oakland this summer.
  • Building a BART connection to the Oakland airport. It could be ready late next year.
  • Adding a carpool lane southbound from Hegenberger Road to Marina Boulevard and rebuilding the Davis Street and Marina Boulevard over-crossings. Work will last three years.
  • Opening carpool lanes from Highway 237 to Highway 101 -- hurray! -- in a couple of weeks.
  • Rebuilding the 280-880 interchange adjacent to Valley Fair. Completion is expected in two years.

  • Q I travel Interstate 680, and extensive work has been done on the freeway from Alamo to San Ramon, making it nice to drive and very scenic. But what about 680 from Walnut Creek to Pleasant Hill? At the split with Highway 242 there is the beginning of a sink area in the third lane, and as you proceed further north at the split there are several areas where the asphalt and cement are eroding. Any help on this matter?

    A Help is coming. This summer Caltrans will replace about 30 concrete slabs between Monument and Willow Pass. And the dip at Monument could be repaired before this winter.

    Q Also, the 680 exit to Sun Valley Boulevard looks terrible. No shrubbery; just dead everything, plus lots of debris.

    Diane Walker

    A Landscape crews will remove any dead shrubs and weeds and pick up litter by the end of this month.

    Q I was headed north to Walnut Creek on 680 one morning when Bishop Ranch shuttle bus number 504, displaying out-of-service signs, went by me in the carpool lane. I caught up to him a few miles later and noted only the driver was on the bus. When the signs say carpools and buses are allowed, I assume that meant buses with passengers. What is the real application of the rule?

    A This bus is operated by County Connection; all paratransit vehicles or transit buses are allowed to drive in the carpool lanes, with or without passengers.

    Q About three years ago, Concord widened Concord Boulevard, but was unable to complete paving due to electrical poles that wound up on the inside of the curb for about three blocks from Sixth Street to near Farm Bureau Road. Do you have any information on when the poles will be moved back behind the curb and paving of this section can be completed?

    A PG&E has obtained right-of-way clearance from all but two owners and hopes to complete negotiations with them by the end of the month. If they do, they'll begin relocating the poles in July and could complete the relocation in October.

    Q Do you know when Sierra Road will be opened up all the way through to Berryessa Road to BART and if it will be widened as it passes behind the golf course?

    Natalie

    A Plans for this improvement are currently being reviewed by the city, and if approval comes this summer, construction could begin soon after. Sierra Road will extend through the northern half of the flea market and will connect with Berryessa Road near Chessington Drive. This will be the first phase of development of the flea market. A traffic signal will be installed at Berryessa Road, but Sierra will remain one lane in each direction.

    Q I have a question. If Chevrolet has a problem with the battery packs in their all-electric cars, would there be a re-volt?
