Q There seems to be a lot of work remaining on Highway 101 in Mountain View. Is the timetable still to open the new lanes by the end of this year? I'm getting worried the answer is no.

Harold Wang

A Your fears are justified. Caltrans now says work will extend into next spring on the widening north of Highway 85 into Palo Alto. That will include repaving.

Q I spotted some signs on Bird Avenue in San Jose which seemed to imply that some road changes are looming. What are they?

Maggie F.

San Jose

A There will be some new lane closures beginning Monday with the Bird Avenue storm sewer project between Coe Avenue and Willow Street. Portions of Bird will be closed to through traffic from 8:30 a.m. to 4:30 p.m. through February.

Q I had to travel downtown and decided to use Coleman, then turn left onto eastbound Hedding Street. Why does Hedding open up to two lanes at Highway 87 and then narrow to one lane past the main jail?

Traffic rushes into the right lane, then has to merge about 100 yards down the road. Wouldn't it be easier to have that as a right-turn lane only?

Michael McWalters

A The city says no. Hedding requires two lanes east of 87 to handle the two lanes going eastbound out of the parking garage on the north side of Hedding just west of San Pedro.

Q About a month ago a reader wrote in complaining about the very large dip on Mary Avenue right at Evelyn and Caltrain in Sunnyvale. At that time you thought it would be fixed before Thanksgiving. A "Dip" sign has been added, but somehow that doesn't feel like it qualifies as a fix.

Assuming some other delay happened, what looks like a new fix date here?

Eric Coblin

Sunnyvale

A Originally this work was planned to be completed in mid-November. But as the city was coordinating schedules with the contractor and Caltrain, it had to move the work to January.

Q Are there plans to add a second lane to the southbound Highway 87 exit from southbound Highway 101? There is plenty of room for the lane and they would practically just have to paint some new lines. It looks like that was the plan. The traffic and all the accidents that that exit causes is crazy, and I just don't understand why it hasn't been done already. ... Any chance of this being improved before 2020?

Scott Dreblow, George Leavell and more

A Maybe, maybe not. The plan is to add a second exit lane and replace the 101 overcrossing by widening De La Cruz Boulevard/Trimble Road to six lanes through the interchange, then to rebuild the southbound exit loop to a partial cloverleaf design and incorporate a new intersection on De La Cruz.

When will this be completed? 2020 is not a bad guess.
