Q I saw a freeway notification sign on south Interstate 280 near Meridian Avenue warning of delays on L.A. freeways Sept. 29-30. What are they referring to exactly? I intend to drive down there next weekend.

A Call this Carmageddon II. Caltrans will close Interstate 405 for 55 hours beginning Friday. It has activated signs around the state to alert drivers of the closure, which is needed to complete a carpool lane through the Sepulveda Pass.

Said Lauren-the-L.A.-Caltrans-Spokeswoman: "This is a very busy and popular route, probably the most highly congested in the state, and we're warning motorists to plan ahead, take alternate routes or modes of transportation if they're coming to or through the Los Angeles region next weekend.

"This was done last year with great success, but we're concerned that motorists won't heed warnings this year because people didn't get out on the road and traffic was relatively light. They may venture out this year, so we want to encourage cooperation again this year."

Added Kelly: "Yikes! I need to take 405 to get from the San Fernando Valley to Venice Beach for a triathlon!"

Yikes, indeed.

Q Gary, we returned from a weekend in Orange County and found that the construction that had clogged up Interstate 5 around Buttonwillow is done, and the road is all clear. Yay!

So there is no more need to cut over to Highway 99, where there is an awful bridge construction bottleneck north of Bakersfield.

But it's not such good news on the Grapevine itself. There are still places where four lanes constrict to three, and the I-5/Highway 14 work created a southbound backup that stretched to Magic Mountain. Thought you'd appreciate the update.

A I do, and I am certain many others will also.

Q Am I the only one who finds the signs on Highway 87 north confusing? It's signed "280 to 680," which leads me to believe that the exit is only for 280 south, which is not the case. What gives?

Matt Birns

A Roadshow gets the credit (or blame). A few years ago readers complained that the north 87 signs only listed the way to 280 -- which turns into north 680 a few miles away. So Caltrans changed the sign to include 680. Your complaint is the first to roll in.

Q It seems more new sport/luxury cars do not have front license plates. My wife's new Lexus hybrid does not even have holes or any noticeable method to mount a front plate. Her new plates just arrived and other than keeping the extra one in the car as proof, what can she do?

Steve Benedict

A Go back to the dealer and ask if front plates can be placed on her car.

Q That is what she did and it all worked out. There were indentations for holes to be formed for a plate holder. Thanks.

Steve Benedict

A Excellent. Two plates are required.

Q I taught my wife how to drive so I can't complain about her driving, but she drives a sports car and I drive a small truck with a camper shell. So I can't really drive too fast and she can. When she first got her sports car we were driving down to L.A. on Highway 99, she was doing better than 90 mph, weaving around trucks and SUVs, when the CHP put a light on her.

As she prepared for the officer to come up to the window, putting on lipstick and touching up her hair, she commented on how she was able to talk her way out of tickets. She is charming. I had to laugh when the lady officer asked her how fast she thought she was going. She got a nice ticket and slowed down for a while, but I sure wish I hadn't bought her a sports car.

A Thanks for today's chuckle.
