Q VTA barely mentioned on its website the most contentious issue of its plan to widen Highway 85 -- the proposed addition of a second carpool lane between Highway 87 and Interstate 280. ... A second carpool lane is not necessary. ... If they are going to add a lane on 85, open it up to solo drivers.

A There's a change in plans. Adding a second carpool lane will likely not happen. That should ease the criticism expressed by many West Valley residents. The VTA is now leaning toward turning the existing single carpool lane into a toll lane and scratching the second express lane. A final decision will be made later this year.

Q I am seeing messages on freeway signs about Interstate 280 being closed as you leave San Francisco over Memorial Day weekend. Why?

Frank Rios

A For bridge work. Southbound Interstate 280 from downtown San Francisco to the Pennsylvania Avenue onramp will be fully closed from Thursday at 9 p.m. through May 27 at 5 a.m. This includes closing the Mariposa Street/18th Street onramp, the Sixth Street/Brannan onramp and the King Street onramp.

More closures are planned for the July 4 and Labor Day weekends.

Q Here are two puzzles about the infamous Almaden Expressway exit from southbound Highway 85. When facing east and waiting at the light at Almaden, there are two right-turn lanes. Each lane has its own light. Of these two lanes, only the left has a "No right on red" sign posted on its signal pole; the right does not.

Does that mean a right turn on red is allowed in the far right lane but not the one to the left of it?

A No. The "No Right Turn on Red" applies to both turn lanes. There are three signals with right-turn arrows on the far side of the intersection to ensure visibility from all angles, in addition to the near right-turn signal.

Q Second puzzle: northbound Almaden Expressway at the first light north of 85. At that point the entrance to Best Buy is to the left and the exit ramp from the freeway enters the intersection from the right. Why should northbound traffic be stopped in this situation? Southbound traffic can certainly not make a left turn, since that would send them head-on into the cars exiting north 85.

Jim Bangsund

A This situation happens when there is a pedestrian waiting to cross the expressway on the north side of the intersection. Otherwise, the northbound expressway light will be green along with the northbound left signal.

Q I just returned to California from Oregon, where drivers are not permitted to fuel their vehicles, when it suddenly occurred to me that there is a whole state full of people who don't know how to safely gas up. What happens when an Oregonian ventures into another state and is suddenly faced with pumping his own fuel?

Kenneth Underwood

A Oh, they'll figure it out.
