Union march expected to snarl LAX traffic on Wednesday (L.A. Times)

The SEIU says that more than 1,000 workers protesting a cut to benefits will march outside the airport on one of the busiest travel days of the years. Authorities message to travelers: arrive at the airport early.

Anti-gridlock group urges speeding up 405 improvements (KCRW's 'Which Way L.A.?)

A short segment on a group pushing for a quicker completion to the project adding a carpool lane to the northbound 405 between the 10 and 101 freeways.

Metro Deputy CEO Paul Taylor Paul said that the project is progressing but that, as with any construction project, “the enemy of progress is surprises” and the Sepulveda Pass project has had a number of temporary delays that needed to be dealt with. But, he pointed out, Metro is working with the contractor to meet deadlines, the carpool lane will be opened in stages beginning next spring/early summer and fully open on schedule by the end of 2013 and that in the end, commuters traveling through the pass will have a faster ride through one of the busiest corridors in the U.S.

Tolls rankle motorist used to the 'free' in 'freeway (New York Times)

The Times does its best to persuade readers that the new ExpressLanes has upset Southern Californians fearful of the next thing they'll be charged for. The best part of the article is a quote from a South L.A. resident wondering why the Westside doesn't have toll lanes. What do you think Westsiders? You want them too?

Poll: Who should be next U.S. Transpo Secretary (D.C. Streetsblog)

Only 323 votes were cast but it's still interesting to see who came in second behind progressive New York City Transportation Commissioner Janette Sadik-Khan. Hint: He's the mayor of Los Angeles! I have no idea if that would ever happen but surely it couldn't hurt having a transportation secretary with ties to Southern California.

A long article in Politico also looks at Villaraigosa and suggests that he could be a serious candidate for the job when Ray LaHood steps down next year. The Mayor says that he's focusing on his current job, which he wants to finish strong before his second and final term ends July 1.
