Q Earlier in the year I recall reading that there were delays due to construction on Interstate 5 from the Bay Area to Los Angeles. I always drive via I-5 through the Grapevine down into the L.A. Basin. Will I incur construction delays or has the work been completed? It's been about six years since I've made the drive.
A You may. While work north of the Grapevine has virtually ended, Caltrans has 12 projects underway on Interstate 5 in Los Angeles County, eight of which are between the Kern County line and Highway 134, which may impact your trip through L.A. Most work is being done at night, typically between 10 p.m. and 6 a.m. If you travel during the day, you should not run into too many construction closures. If you hit the road at night, you almost definitely will.

Q About 45 miles south of the I-5 and Highway 152 interchange there are two sections of road repair that haven't been finished in at least six months.
Sections in the northbound right lane are ground down and appear ready for asphalting. The sections start before Kamm Avenue and end just past Manning Avenue, and in total there is about five miles of ground-down pavement. Traffic tends to slow in these areas as most folks move into the left lane to avoid the rough road. Do you know when it might be fixed, Mr. Roadshow?
A Interim repairs are coming soon. In addition, Caltrans will begin a concrete panel replacement project in both directions from the Grapevine undercrossing to Highway 99 this spring.
Q Just a comment regarding I-5 and the missing Botts' dots. I'm more bothered by drivers who see I-5 as their personal racetrack! Speeds of 80, 85 and probably some 90s seem the norm for many. We spend a lot of time on I-5, both to SoCal and the Oregon border, and speed is a real issue.
A But ...
Q It seems to me that some of the freeways in the Bay Area and the state, especially I-5, have archaic speed limits. When was the last time speed limits on our freeways were determined? With the way cars are designed today, is it conceivable cars could go 80 on I-5? Most people already go that fast if not faster if the CHP isn't watching. Is it possible the 70-mph speed limit will be raised in the coming years?
A No. The speed limit was last raised in 1995 and there has been no move to increase it.
Q How are exit numbers on major highways determined? North to south or east to west?
A South to north, and west to east. Each exit number is determined by the number of miles it is from the beginning of the route. For example, on Interstate 5, exit No. 1 is just north of the Mexican border. Numbering continues all the way to the last offramp (Exit 796) before the freeway enters Oregon, 796 miles north of the Mexican border.
