Q I think I have a better suggestion for the woman from Sacramento who has had problems with the gas nozzle clicking off unless she is holding the handle. I've had the same problem. If flipping the auto lever doesn't work, there is another, smaller lever further down from the original lever. You can push this smaller lever toward the hose and it will engage manually. Then it works the same way, and gas will stop pumping when the tank is full.

A And here is why some gas nozzles are difficult to use. Three years ago the Office of the State Fire Marshal ordered locking latches on gas nozzles from vapor system technologies because of splashing when filling up, said Tim Low of San Francisco, who cited a 2010 report on the issue: "Many operators apparently chose to just remove the locking latches instead of purchasing new nozzles at a cost of about $350 per nozzle," he said. "About one-third (3,000 statewide) don't have the latches now, according to the California Service Station and Automotive Repair Association, an industry advocate."

Q With the new section of the Bay Bridge now in use, I am wondering if the merge length on the eastbound onramp at Treasure Island will be increased. It is very short and requires careful timing of how quickly my truck engine will accelerate vs. how quickly an oncoming car will appear around the curve. For that very reason, I rarely visit the island.

A Mrs. Roadshow and I had to nervously navigate this short ramp during our recent drive across the new span. The good news: a longer, permanent replacement will be built once the old S-curve is demolished and the bike/pedestrian path is extended to Yerba Buena Island. Until then, pay attention and keep your engines well-tuned.

Q Why are they making Interstate 680 between Crow Canyon Road and Sycamore Valley Road look like L.A.? Auxiliary lane for two miles? They moved back the sound walls (removed the old ones and built new ones behind them). The sign says "auxiliary lanes." They basically removed every tree along the freeway on both sides. Looks like Glendale now.

I'd rather have the trees back. Get rid of the lane reduction on south 680 after South Main instead please.

A I like auxiliary lanes, which are exit-entrance lanes that run between interchanges and can ease merging difficulties. There are no immediate plans for a continuous lane here on south 680.

Q They've made several changes on Interstate 80 over the last few days through Richmond and El Cerrito. What are they doing? What is that all about? ... Can you tell me why the lanes of I-80 were changed to mini S-curves between Albany and El Cerrito? Caltrans removed the shoulders so there's nowhere to pull over to get out of traffic in case of an emergency, and these changes have created some pretty scary moments for commuters trying to adjust.

A Work is underway in earnest for what is called the Integrated Corridor Mobility project, which will provide safety improvements and hopefully speed up the commute from the Carquinez Bridge to the Bay Bridge. One of the changes will be a variable speed limit that will rise and fall depending on congestion.

The contractor has re-striped I-80 at several locations between Powell Street in Emeryville and Potrero Avenue in El Cerrito, giving crews room in the median to begin foundation work for electronic informational signs that will be installed next year. In addition, ramp metering work continues here as well. Watch for signs of closings at Ashby Avenue and University Avenue next week.

The $80 million project could be done late next year. Go to www.dot.ca.gov/dist4/projects/80icm for details.
