Q: With $142.1 million being spent on repaving Interstate 680, I hope it is being repaved all the way from San Jose to Interstate 80 or the money would be wasted.
Like Mr. Roadshow’s Facebook page for more questions and answers about Bay Area roads, freeways and commuting.
A: This project is located on I-680 from Koopman Road in Sunol to Alcosta Boulevard in Dublin in Alameda County. This should address the various portions of freeway that are in advanced phases of cracking and breaking loose. Work could begin late this year.
The section of I-680 south of Sunol through Fremont is being repaved now and should be done when express lanes are ready.
As for repaving 680 up to I-80, there is no time table for that stretch yet.
Q: I’m laughing at your response about repaving Highway 12 between Suisun and Rio Vista. I moved to Rio Vista six years ago. That section has been a mess for all six years. Occasional patchwork has made a slight improvement but soon again the road is a mess.
Saying the “work will start any day now” is too funny because “any day” could mean just that — any day way in the future. I hope I’m wrong but I’m not holding my breath.
Currently, a turnaround is being installed at the intersection of 12 and 113 and the Department of Transportation is replacing channel pylons. Oh, the joys of living in the country surrounded by two-lane roads and a draw bridge.

A: Be hopeful. Caltrans will begin overnight paving work to repair Highway12 between Shiloh Road in Solano County and Walters Road in Suisun and between Church Road and Currie Road in Rio Vista this month and running through October. The work will be done between 10 p.m. and 5 a.m. with overnight lane closures and one-way traffic controls.
Q: For a period of time my wife and I have commented on how dark Caldecott tunnels #1 and #2 were, and how it would be nice if Caltrans could power wash and paint the walls to brighten it up. It appears as though there has been some such work. The walls are brighter, the tunnels less dreary. Will there be any further improvements?
Tracy Woodard, Martinez
A: The six tunnels and tubes are cleaned in six separate days over a two-week period each quarter. One bore per night will be closed, leaving the second bore in the same direction open. Caltrans uses a scrub truck to soften the sticky dust on the tunnel wall followed by truck tanker to pressure wash the walls.
Workers on foot concentrate on breaking down and removing calcium deposits on the drainage areas.
