Q When will the agony be over at the Interstate 880 widening between 237 and 101? Most importantly, is there any way to avoid this fiasco in the meantime, other than staying home in bed?

Rick Tata

A No, but the agony will soon end. Caltrans says work could end before July 4 on extending carpool lanes from 101 to 237. Last week the diamond lane markings were installed.

Q As I've watched the widening of 880 from 237 to 101, I was wondering how they would handle the merge at 101 since they are creating yet another lane on 880. Now that it's almost complete, I see the answer: They're not doing anything to ease the merge!

It has become a bigger, more dangerous mess than ever, with cars trying to merge right to get onto 101 south, and other cars trying to get onto 880 south from 101 north. It is a disaster. I'm sure flyovers would be a very expensive solution, but is there any relief planned?

A No. Workers are adding a carpool lane, but they aren't going to tinker with the 101 interchange. Now onto other roads we loathe.

Q Please don't forget the Tri-Valley Interstate 580 freeway area. It's getting worse, if that's possible, and is now so bad with the bumper-to-bumper 18-wheel traffic that it's almost impossible to get in the right lane to exit. Does Caltrans have plans to alleviate this problem?

A Several, including the $49 million project to build a truck climbing lane eastbound from Greenville Road to North Flynn Road. And 580 is being widened westbound with a carpool lane from the Greenville overcrossing to Isabel Avenue in Livermore. And the current carpool lane will be converted to an express or toll lane east of Greenville Road to west of San Ramon Road.

Also, auxiliary lanes are coming eastbound between Isabel Avenue and North Livermore Avenue and North Livermore Avenue and First Street in Livermore.

Total cost: in the $200 million-plus neighborhood. All work should be completed by 2015.

Q The other day I had yet another hairy white-knuckle trip down San Jose-Soquel Road through the Santa Cruz Mountains. I was sure it was the end. Unfortunately, I feel this way frequently while driving this road.

I don't like driving over 40 mph here because in the summer there are bicyclists sharing the road who I completely respect for their bravery. In the winter there are fallen tree branches lying in the road, and sometimes the entire tree joins the party. I have encountered everything from stray dogs, deer and coyotes to boulders. One day, I came around a turn and the entire lane had disappeared -- into the reservoir. Understandably I don't like to speed on this road.

So, when did the 40-mph speed limit become the minimum speed limit? The average speed on the San Jose-Soquel Speedway (oops, Road) just keeps going up over the years. If you are going less than 50 mph, watch out.

Yikes. Is anyone else having trouble with this road lately?

A If they are, I'm certain we'll hear from them.

Q Mr. Roadshow, please tell me something is in the works to make the exit to Page Mill Road off Interstate 280 safer, especially coming southbound. In the mornings, traffic backs up onto the freeway, and while there is an exit-only lane, people queue up in two lines: one in the exit lane and one in the shoulder.

This has become even more of a problem with greater traffic due to large companies (Tesla, SAP and VMware) located off this exit. I think it's great there's booming business, but it's scary to get to work in the morning.

Could Caltrans look into extending the multiple lanes from way down near the stop sign at the intersection up toward the freeway?

A That could be a long-term goal, but there is a project in the works to install a signal at the southbound 280/Page Mill intersection that traffic officials think will ease the backups. Installation could be underway in a year.
