Q There is growing talk about running light rail down the median of Highway 85 if the Measure B sales tax is approved. Can you shed some light on what route this would take? As far as I know, there is only space to build light rail between Highway 87 and Interstate 280, which would create a connection between South San Jose and Cupertino. Is this a useful route? I don’t think so unless it can continue farther north and connect with the Mountain View Caltrain station.

Roadshow: San Jose testing app to improve traffic flow A This idea of extending light rail along Highway 85 may gain steam instead of adding a second carpool lane between 87 and 280. The tax would earmark $350 million for the 85 corridor and a trolley line on 85 could go as far north as 101 in Mountain View. I doubt that would cover the cost of the extension. Decisions on what projects will be done first could be made next year.

Q Why did the traffic engineers change the lanes eastbound on Capital Expressway after you cross under Highway 87? And why did they change the traffic flow both northbound and southbound on Narvaez at Capital? These changes have caused greater congestion all day.

Are they thinking about re-timing the signals here?

Dave Kurze

A Yes. This is part of the traffic mitigation from development on Communications Hill. There is now an additional eastbound lane on the expressway from the 87 southbound off-ramp through the intersection, which county engineers say has reduced the backup.

Plus, there are now two crosswalks crossing the expressway at Narvaez and new signals with left-turn arrows. A new signal timing plan will be done soon.

But cautions Masoud-the-County-Man: “This intersection is mainly congested due to the ramp metering during morning peak hours and that part of it may not be resolved with this current improvement effort.”

Q Are there any plans to widen Highway 156 between San Juan Bautista and Hollister, as well as the connection from 101 to Hollister to Highway 25? There are currently almost 4,000 new homes to be built in our community, and no one seems to care about roads.

Sandy Cabral

A Good news on 156. There are plans to turn it into a four-lane expressway in and near San Juan Bautista to Hollister. Construction on the $44.6 million job should start in 2019 and take two years.

As for the 101 to 25 ramp, it’s in the long-range plans, very long-range. Try a decade. Or two.

Q Are there plans to convert St. James Street between Market and 4th Street and Julian Street between Market and 3rd Street from one-way to two-way streets in San Jose? It’s very confusing how these two streets go from two-way to one-way and then back to two-way within a span of three or four blocks.

Rick Upton

San Jose

A As part of the city development of this area, West St. James will go from a one-way eastbound street to a two-way street from Highway 87 to Market Street. Julian will be two lanes going west.
