Q One CHP officer asked another officer how he was able to determine the drunk drivers on southbound Interstate 680 between I-580 and the Sunol Grade. He said, "Easy, they are the ones driving straight in lane number one. The sober drivers are the ones swerving around all the potholes in the road."

A Today is a day where humor is needed, as it's all about roads in desperate need of paving and pothole filling.

Q Do you know when Caltrans is going to address the multiple mine fields on Interstate 680 between Fremont and Pleasanton, which has to be the worst stretch in the Bay Area? The No. 3 lane between Bernal and 84 is literally turning into dust. Some of the patches (most of which are only a couple of years old) are disintegrating to the point where you have to straddle the breakdown lane to avoid bottoming out.

A I hate when that happens. There are plans to replace the broken concrete next summer southbound. And in 2017, the state will pave the northbound side from 237 to 84.

Q We recently traveled in our motor home west on Interstate 580/Interstate 205 over the Altamont Pass and what a mess all the lanes are. We drove in the right-hand lane and watched people in other lanes dodging potholes as well. Are they ever going to repave these lanes? ... The far right lane is so bad that you cannot use it without causing serious damage to your tires and suspension. ... The condition on both sides is absolutely horrid, with potholes at least 6 feet long and 3 feet wide.

A There is a major rehab project scheduled to start in two years on I-580. It will include the ramps from San Joaquin County to North Flynn Road eastbound and from San Joaquin County to Greenville Road westbound.

The state will also do some small paving jobs this summer near Grantline Road and Stonecut.

Q Interstate 80 from Albany north has huge gaping cracks and holes. A miserable ride. ... Does Caltrans plan to repave I-80 between Cummings Skyway and the Hercules exit? The two inside lanes are in need of repair. ... As someone who has traveled I-80 and suffered tire damage from too many potholes to mention, I was curious about repaving plans. The stretch from Albany to the Maze has been repaved in both directions and is a pleasure to drive. When can we expect the stretch from the Contra Costa County line to the Carquinez Bridge to be repaved?

A Concrete slab repairs aren't scheduled until 2019 on this stretch of I-80, but the state has sealed some cracks and will keep a watch on the area.

Q I noticed that 680 through the Concord/Pleasant Hill area has been getting the much needed road grinding. Will this also be done on Highway 242? It needs it as well.

A No. There is nothing planned in the near future.

Q Are there plans to repair Chabot Road in the Rockridge neighborhood of Oakland? It is filled with potholes that are difficult for cars and especially bicycles. There has been a lot of construction in and around the road over the years (Chabot Elementary, Seneca Center, and most recently work on cross street Golden Gate Avenue). But the road has never been repaved in several years, and attempts at patching are few and far between.

A Good news for drivers and bicyclists. Oakland will repave Chabot this fall. The project includes replacing the sidewalk damaged by trees, curbs and gutters, and upgrades to 30 ramps to comply with requirements for the disabled, plus installation of "sharrows" -- used in lanes shared by bicyclists and motorists when there is not enough room for a bike lane.

Q Trimble Road in San Jose is disintegrating between Montague Expressway and Junction Avenue.

A Yes it is, and Trimble has been on the city's radar for some time. But there are four different sanitary sewer projects that will dig up various sections of Trimble over the next 18 months, so the city has decided to delay any resurfacing of Trimble until sewer work is completed.
