Q Recently we took Interstate 80 to Lake Tahoe and noticed Caltrans was not doing any work on it this summer in the Sierra. There are still very rough slabs on east 80 between Alta/Baxter and Colfax, and on west 80 in the Blue Canyon/truck brake-stop area, especially the right lane. It is so bad that most cars drive only in the left lane.

Also, some replaced slabs are already showing pitting from chains. Please tell me that Caltrans isn't finished with I-80 yet.

A Finished with working on I-80 through the mountains? Never.

There's a paving project scheduled from Truckee to the Nevada state line late this summer. Also, there are guard rail and bridge seismic retrofitting projects on I-80 planned. Said Steve-the-Caltans-Man: "We're never really finished with I-80."

Q When they propose putting a traffic light on a state highway, are there any stipulations that delays should have minimal impact?

A For Caltrans to install a traffic signal, it must either improve safety and/or help improve mobility and minimize delays. Caltrans analyzes the intersection using traffic simulation software to determine the signal timing, cycle length and sequences.

Why do you ask?

Q Try driving Highway 120 to Yosemite late at night. It does not matter the traffic loads, the lights stop traffic at each and every light. I just drove this route at 11 p.m. to midnight and had to stop at almost every light east on 120 from Highway 99. Maintained the speed limits required through the various towns and there was not any train traffic in Escalon, yet still had to stop at two sets of the lights there. Oakdale was a mess with the light on 120 at River Road stopping traffic for some phantom cross traffic.

A Caltrans has been reviewing the signals on the state routes in Oakdale and Manteca and found that the signal at Highway 120 and Rodden & River Road had a malfunctioning sensor loop that has since been repaired. Other signals were OK.

Sometimes signals are set on a timer when maintenance is working in the area, and there are times when signals outside the state's right-of-way may need adjusting.

Q Do the light patterns on 120 change at night and is that typical?

Frustrated going to Yosemite

A Yes, they do change as traffic gets lighter.

Q Is Camden Avenue between Bascom and Leigh about to be repaved? There are lots of new spray-paint markings on the road.

A Segments of Camden are scheduled for work over the next two years. The spray-paint markings identify locations where the city will repair areas that have failed. Up first, the segment between Highway 85 and Coleman Road this summer. The stretch from Bascom-Hillsdale and Coleman-Almaden Expressway will be done next year.
